Tscheligi, Manfred, Meschtscherjakov, Alexander, Weiss, Astrid, Wulf, Volker, Evers, Vanessa and Mutlu, Bilge (2012): Exploring collaboration in challenging environments: from the car to the factory and beyond. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 15-16.

We propose a daylong workshop at CSCW2012 on the topic collaboration in challenging and difficult environments, which are to our understanding all contexts, which go beyond traditional working/office settings topic. Examples for these environments can be the automotive context or the context of a semiconductor factory, which show very specific contextual conditions and therefore offer special research challenges: How to address all passengers in the car, not only the driver? How to explore operator tasks in a cleanroom? How could the long-term (social) collaboration of robots and humans be investigated in privacy critical environments?

Gridling, Nicole, Meschtscherjakov, Alexander and Tscheligi, Manfred (2012): I need help!: exploring collaboration in the car. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 87-90.

Today a huge number of different driving assistance and navigation systems are available on the market. Often these systems fail to take into account the social nature and collaborative mechanism of driving. This paper presents a two-month ethnographic study of drivers and passengers, with the goal of understanding social and collaborative in-car activities while driving to inform in-car navigation design. We found that human assistance and collaborative behavior varied among different contextual situations. Above that User Experience (UX) factors such as trust and perceived safety have a main influence on the type of front-seat passenger assistance and level of collaboration. Based on these observations we present a design approach for collaborative navigation devices that can be used to inform future research and practical applications in automobile collaboration.

Kluckner, Patricia M., Buchner, Roland, Weiss, Astrid and Tscheligi, Manfred (2012): Repair now: collaboration between maintainers, operators and equipment in a cleanroom. In: Companion Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 143-146.

It is greatly acknowledged in the CSCW community that supportive technology needs to adapt to its contextual usage to increase the collaboration between different user groups. Based on a Contextual Inquiry (CI) in the cleanroom in a semiconductor factory, we identified the maintainers working routines and their usage patterns with various maintenance devices. In the cleanroom maintainance tools could bridge the physical gap between operators and maintainers. In particular reporting tools should link the information gap. In this paper we will present design implications derived from the CI towards a novel-reporting tool for maintainers to support this cooperation between maintainers and operators in the cleanroom.

Buchner, Roland, Wurhofer, Daniela, Weiss, Astrid and Tscheligi, Manfred (2012): User experience of industrial robots over time. In: Proceedings of the 7th International Conference on Human-Robot Interaction 2012. pp. 115-116.

This paper reports about a User Experience (UX) study on industrial robotic arms in the context of a semiconductor factory cleanroom. The goal was to find out (1) if there is a difference in the UX between robots used over years with a strict security perimeter (robot A) and a newly installed robot without security perimeter (robot B), and (2) if the UX ratings of the new robot change over time. Therefore, a UX questionnaire was developed and handed out to the operators working with these robots. The first survey was conducted one week after the deployment of robot B (n=23), the second survey (n=21) six months later. Thereby, we found that time is crucial for experiencing human-robot interaction. Our results showed an improvement between the first and second measurement of UX regarding robot B. Although robot A was significantly better rated than robot B in terms of usability, general UX, cooperation, and stress, we assume that the differences in UX will decrease gradually with prolonged interaction.

Strasser, Ewald, Weiss, Astrid and Tscheligi, Manfred (2012): Affect misattribution procedure: an implicit technique to measure user experience in hri. In: Proceedings of the 7th International Conference on Human-Robot Interaction 2012. pp. 243-244.

This paper suggests new methodology for measuring User Experience in HRI. We suggest using implicit attitude to predict User Experience (Affect). Therefore we show a first validation study. The study uses short videos of a robot (IURO -- Interactive Urban Robot) approaching a person and asking for the. IURO either approached a walking or a standing person. We measured people's implicit attitude towards the robot with the Affect Misattribution Procedure (AMP). The results show that a walking person being approached by the robot evolves an implicitly more negative attitude in the observing participant whereas corresponding questionnaire items showed no difference in attitude for the approach behaviour. We conclude from these results that measuring implicit attitude in HRI is valuable for the evaluation of the User Experience of a robot.

The results from an empirical study on the impact of a robot's approach trajectories on its social acceptance are presented. An online survey presenting short videos of a robot (IURO -- Interactive Urban RObot) approaching a person in a public space and asking for help was shown to the users. IURO either approached a walking or standing person. The results show that walking participants preferred to be approached from the front left or front right direction rather than frontally. However, when they are standing all three approach directions were acceptable.

Hussain, Zahid, Lechner, Martin, Milchrahm, Harald, Shahzad, Sara, Slany, Wolfgang, Umgeher, Martin, Vlk, Thomas, Koeffel, Christina, Tscheligi, Manfred and Wolkerstorfer, Peter (2012): Practical Usability in XP Software Development Processes. In: Proceedings of the 2012 International Conference on Advances in Computer-Human Interactions 2012. pp. 208-217.

This paper describes the experiences made and lessons learned in an Extreme Programming (XP) software development project. We investigate the potential of XP to produce user experience-optimized products by including HCI experts in the team. We relate the software development method to user-centered design instruments and propose solutions to different user experience integration problems. Additionally, the practicability of different HCI instruments regarding solving those problems is examined. The analyzed instruments and methods are: user studies, personas, usability tests, user experience expert evaluations, and extended unit tests. The conclusion provides tips and tricks for practitioners.

Wckl, Bernhard, Yildizoglu, Ulcay, Buber, Isabella, Diaz, Belinda Aparicio, Kruijff, Ernst and Tscheligi, Manfred (2012): Basic senior personas: a representative design tool covering the spectrum of European older adults. In: Fourteenth Annual ACM SIGACCESS Conference on Assistive Technologies 2012. pp. 25-32.

The persona method is a powerful approach to focus on needs and characteristics of target users, keeping complex user data, numbers and diagrams alive during the whole design cycle. However, the development of prosperous personas requires a considerable amount of time, effort and specific skills. This paper introduces the development of a set of 30 basic senior personas, covering a broad range of characteristics of European older adults, following a quantitative development approach. The aim of this tool is to support researchers and developers in extending empathy for their target users when developing ICT solutions for the benefit of older adults. The main innovation lies in the representativeness of the basic senior personas. The personas build on multifaceted quantitative data from a single source including micro-level information from roughly 12,500 older individuals living in different European countries. The resulting personas may be applied in their basic form but are extendable to specific contexts. Also, the suggested tool addresses the drawbacks of current existing personas describing older adults: being representative and cost-efficient. The basic senior personas, a filter tool, a manual and templates for "persona marketing" articles are available for free online under http://elderlypersonas.cure.at.

Moser, Christiane, Fuchsberger, Verena and Tscheligi, Manfred (2012): Rapid assessment of game experiences in public settings. In: Proceedings of the 4th International Conference Fun and Games 2012. pp. 73-82.

Enjoyment and curiosity are an essential motivation for children to play games in order to engage them in the game play. When two users play against each other they also share experiences, i.e. co-experience. The evaluation of these experiences exceeds usability (or playability) by not only investigating the relation between the player and the game, but also between several players. We assessed users' game experiences in a public setting (shopping mall), which is challenging. This specific context is very diverse, as in the morning it is very quiet until the shops open, then it fills up with people and during the rush hours it is sometimes very crowded. In order to best suit this context for evaluating the different experiences children have while playing games we adapted and extended our previous feedback questionnaire, which originally investigated only the fun/enjoyment of games, by rapidly assessing also curiosity and co-experience.

Buchner, Roland, Weiss, Astrid and Tscheligi, Manfred (2011): Development of a context model based on video analysis. In: Proceedings of the 6th International Conference on Human Robot Interaction 2011. pp. 117-118.

This paper reports on the analysis of video footage of a human-robot study in public place regarding context factors that significantly influence the interaction. Therefore, a coding scheme was developed which was later used to analyze the video footage of the human-robot study. To ensure the validity of the coding, the video footage was coded independently by two students and afterwards the Cohen's Kappa was calculated to ensure the intercoder reliability. This calculation served as a basis for the creation of the first context model which shows factors that influence the interaction. This approach could show that it is possible to extract valid context factors and to create a context model based on video annotation. These factors should then be further tested in lab-based studies to get a better understanding of how they affect the human-robot interaction.

Frster, Florian, Weiss, Astrid and Tscheligi, Manfred (2011): Anthropomorphic design for an interactive urban robot: the right design approach. In: Proceedings of the 6th International Conference on Human Robot Interaction 2011. pp. 137-138.

The paper presents the first step of a user-centered design process for a robot designated to operate in urban public space. A participatory design workshop was conducted to challenge the anthropomorphic design approach assumed by the designers and elicit user requirements for the design. In contrast to the expectations, the results show a tendency towards a preference of a non-anthropomorphic design.

Mirnig, Nicole, Weiss, Astrid and Tscheligi, Manfred (2011): A communication structure for human-robot itinerary requests. In: Proceedings of the 6th International Conference on Human Robot Interaction 2011. pp. 205-206.

To analyze the formula for success of human communication, we examined dialogs between human interactors who were asking for directions in public place and extracted those elements that are responsible for making a dialog succeed or fail. Then, we tried to rate the elements according to the grade of their influence. Based on this rating and on the Shannon&Weaver model of communication, we created a communication structure for successful human-robot communication on which further research may be based to make human-robot communication as effective as possible.

Deutsch, Stephanie, Begolli, Genc, Lugmayr, Martin and Tscheligi, Manfred (2011): Assisted collection and organization for laddering interview data. In: Proceedings of ACM CHI 2011 Conference on Human Factors in Computing Systems 2011. pp. 647-650.

Today several narrative techniques for acquiring subjective information from users are widely applied in HCI Research. As an emerging technique in this field, the laddering approach is widely used in marketing research contexts to learn more about personal values and customer behaviors. However, the method is in search of serious improvement in terms of ensuring objectivity and reliability of the resulting data. In this paper we propose a tool that supports the collection and organization of qualitative data from narrative laddering interviews. We describe how LadderAssist supports the interviewer by preventing errors in data acquisition and saving time in data organization and processing.

The school context provides a fruitful and at the same challenging environment to get children engaged in creative development activities. Within this paper we highlight the opportunities and challenges when involving children in the design and development process of interactive technologies with a special focus on this educational context. A summary of the contributions to this IDC 2011 workshop is provided pointing out the main highlights from the position papers. We conclude by discussing future research challenges and opportunities when working with children in the school context.

Obrist, Marianna, Beck, Elke, Wurhofer, Daniela and Tscheligi, Manfred (2011): Experience characters: a design tool for communicating mobile phone experiences to designers. In: Proceedings of 13th Conference on Human-computer interaction with mobile devices and services 2011. pp. 385-394.

Different methods, techniques and tools exist for supporting design activities in a user-centered design process. Due to the increasing relevance of experience-centered design, the need to advance existing design methods and tools becomes evident. Within this paper we present "experience characters" as a design tool for communicating a richer understanding of mobile phone experiences towards designers. We conducted a qualitative text analysis study of written experience reports from an online forum in the tradition of grounded theory. Major experience types were grouped into categories and further transformed into five fictive characters that are easy to remember and likely to invoke empathy in design. Thus, designers' communication on and understanding of mobile phone experiences are supported. We describe in detail the steps taken for analysing experience reports and developing the experience characters, including relevant properties for informing and supporting an experience-centered design process.

Obrist, Marianna, Wurhofer, Daniela, Beck, Elke, Karahasanovic, Amela and Tscheligi, Manfred (2010): User experience (UX) patterns for audio-visual networked applications: inspirations for design. In: Proceedings of the Sixth Nordic Conference on Human-Computer Interaction 2010. pp. 343-352.

This paper summarizes best practices for improving user experience (UX) of audio-visual networked applications such as YouTube, Flickr, or Facebook. Designing for a good UX is becoming increasingly important within the HCI community. However, there is still a lack of empirically based knowledge on how to design audio-visual networked applications for an optimal UX. Based on studies with more than 8000 users of ten different audio-visual networked applications, we have developed 30 user experience patterns (short UX patterns). Our UX patterns are build on the end users' experiences investigated in lab and field studies in three different European countries. Most other pattern collections are based on the experience of designers or developers. In this paper we will present how we have developed the UX patterns and will describe the major UX problem areas found in detail. Our pattern collection can be useful to the designers of audio-visual networked applications and for the researchers working in the area of UX by providing empirical evidence on identified UX problems and suggestions for solutions referring to one or more of our UX patterns.

Wimmer, Benjamin, Wckl, Bernhard, Leitner, Michael and Tscheligi, Manfred (2010): Measuring the dynamics of user experience in short interaction sequences. In: Proceedings of the Sixth Nordic Conference on Human-Computer Interaction 2010. pp. 825-828.

In this paper we discuss the dynamics of user experience in short interaction sequences (SIS). By splitting up complex tasks into several smaller sub steps -- and therefore transforming it into a SIS -- it allows identifying and measuring dynamic changes of specific UX factors throughout the task. This enables generating a more detailed view than by common approaches like pre and post task evaluation. Through a study we examined the factors pleasantness and arousal on the basis of a generic online shopping process. For validation, two different methods (Emocards, Sensual Evaluation Instrument) were used for measurement. Results show different dynamics of UX for each of the evaluated sub steps and we therefore conclude that singular UX measurement (at one point of time) or pre and post task evaluation is not sufficient for getting a full picture of UX.

User experience is highly influenced and even changed by the context in which it occurs. In this SIG session we want to discuss how specific contexts influence various aspects of user experience. So far, both concepts "user experience" and "context" have been discussed a lot to various extent and in different dimensions. With this SIG, we aim to bring both concepts together, highlighting the differences arising from the consideration of different specific contexts and their relevant user experience factors. Thus, we reach a more comprehensive understanding of "contextual user experience", which opens up different roads for research and challenges the HCI community in all design and development phases. We will discuss user experience as focal point of user interface and interaction design bound to specific situational cases.

Weiss, Astrid, Igelsbck, Judith, Tscheligi, Manfred, Bauer, Andrea, Khnlenz, Kolja, Wollherr, Dirk and Buss, Martin (2010): Robots asking for directions: the willingness of passers-by to support robots. In: Proceedings of the 5th ACM/IEEE International Conference on Human Robot Interaction 2010. pp. 23-30.

This paper reports about a human-robot interaction field trial conducted with the autonomous mobile robot ACE (Autonomous City Explorer) in a public place, where the ACE robot needs the support of human passers-by to find its way to a target location. Since the robot does not possess any prior map knowledge or GPS support, it has to acquire missing information through interaction with humans. The robot thus has to initiate communication by asking for the way, and retrieves information from passers-by showing the way by gestures (pointing) and marking goal positions on a still image on the touch screen of the robot. The aims of the field trial where threefold: (1) Investigating the aptitude of the navigation architecture, (2) Evaluating the intuitiveness of the interaction concept for the passers-by, (3) Assessing people's willingness to support the ACE robot in its task, i.e. assessing the social acceptability. The field trial demonstrates that the architecture enables successful autonomous path finding without any prior map knowledge just by route directions given by passers-by. An additional street survey and observational data moreover attests the intuitiveness of the interaction paradigm and the high acceptability of the ACE robot in the public place.

Schrammel, Johann, Leitner, Michael and Tscheligi, Manfred (2009): Semantically structured tag clouds: an empirical evaluation of clustered presentation approaches. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2037-2040.

Tag clouds have become a frequently used interaction technique in the web. Recently several approaches to present tag clouds with the tags semantically clustered have been proposed. However, it remains unclear whether the expected gains in performance and advantages in interaction actually can be realized as no empirical evaluations of such approaches are available yet. In this paper we describe a series of experiments designed to evaluate the effects of semantic versus alphabetical and random arrangements of tags in tag clouds. The results of our work indicate that semantically clustered tag clouds can provide improvements over random layouts in specific search tasks and that they tend to increase the attention towards tags in small fonts compared to other layouts. Also, semantically structured tag clouds were preferred by about half of the users for general search tasks. Tag cloud layout does not seem to influence the ability to remember tags.

Leitner, Michael, Subasi, zge, Hller, Norman, Geven, Arjan and Tscheligi, Manfred (2009): User requirement analysis for a railway ticketing portal with emphasis on semantic accessibility for older users. In: Proceedings of the 2009 International Cross-Disciplinary Conference on Web Accessibility W4A 2009. pp. 114-122.

In this paper, we present the results from a survey on user requirements for older users of online ticketing services of a nationwide railway ticket and travel information portal. Our survey shows that older users differentiate in their attitude towards internet according to their experience with internet services and the service provided, not only according to their age. Further, our study indicates that in contrary to common belief advertisement or interactive elements are not perceived as negative all the time. The results of a questionnaire with 1200 responses, focus groups, interviews and qualitative analysis of user feedback also indicate that in order to improve and optimize the usage of the online system for older adults, it is needed to supply the system not only with technical accessibility requirements but also with an understanding of universal accessibility requirements. Universal requirements are defined by real user and usage cases and they consider standardization on not only coding but also predictability of usage and same patterns of interaction for similar websites.

Effective collaboration between robots and humans is not only a question of interface design and usability, but also of user experience and social acceptance. To investigate these aspects for Human-Robot Collaboration with the HRP-2 robot, two video-based focus groups enhanced with creative stimuli were conducted. The following research question was addressed: Is the HRP-2 robot perceived differently in an autonomous collaboration condition compared to a tele-operated collaboration condition, in terms of social acceptance and user experience?"The results show that participants in general are open to a humanoid robot as working partner as long as there is a clear distinction between a human and a robot, in terms of tasks and working procedures. Furthermore, participants stated a positive attitude toward the remotely-controlled HRP-2 robot.

This article reports on a user study conducted to asses the credibility of a humanoid robot. The study set-up was based on the "Monty Hall Problem. Overall 13 people between the ages of 19 and 84 took part in the study (7 male and 6 female). The experiment was set up as a card-game where the participant had to guess which of the three cards shows a price. At one point of the experiment the robot advised the participant to change his/her mind and choose another card. During the user study the participants had to fill in a questionnaire on their level of certainty about their choice and the credibility of the robot. The results showed a significant correlation between the believability of the robot and the certainty in the decision made. Furthermore, the outcomes showed differences between participants who followed the robot's advise and participants who did not, regarding credibility, certainty of the decision made and the estimation whether the robot was helpful or not.

This paper reports on the evaluation of the ICRA 2008 Human-Robot Interaction (HRI) Challenge. Five research groups demonstrated state-of-the-art work on HRI with a special focus on social and learning abilities. The demonstrations were rated by expert evaluators, in charge of awarding the prize, and 269 participants, i.e. 20 percent of the conference attendees through a standardized questionnaire (semantic differential). The data was analyzed with respect to six independent variables: expert evaluators vs. attendees, nationality of participants, origin region of the demo, age, gender and knowledge level of the attendees. Conference attendees tended to give higher scores for Social Skills, General Impression, and Overall Score than the expert evaluators. Irrespectively of the level of knowledge, age, and gender, conference attendees rated all demos relatively homogeneously. However, a comparative analysis of the conference attendees's ratings nationality-wise showed that demonstrations were rated differently depending on the region of origin. Conference attendees for the USA and Asian countries tended to rate demos from the same country of origin more frequently and more positively.

Wilfinger, David, Weiss, Astrid and Tscheligi, Manfred (2009): Exploring shopping information and navigation strategies with a mobile device. In: Proceedings of 11th Conference on Human-computer interaction with mobile devices and services 2009. p. 19.

In this article a field trial is presented that explores shopping information and navigation strategies and evaluates if the spectacles camera is beneficial as mobile device for this research context. The spectacles camera, a small camera installed in a pair of glasses, was used as exploration instrument in a shopping mall where passers-by could take part in a field trial on a voluntary basis. The goal of the field trial was twofold: 1.) Gaining insights on shoppers' behavior. 2.) Investigating the feasibility of the spectacles camera as exploration instrument. The field trial gave insights on navigation patterns and constituting elements of interest points of participants' shopping behavior, while the spectacles camera proved its value for investigating shopping strategies in the field.

In: Proceedings of 11th Conference on Human-computer interaction with mobile devices and services 2009. p. 67.

We present a study investigating two novel mobile services supporting querying for information in the urban environment using camera equipped smart phones as well as two different ways to visualize results -- icon-based visualization and text-based visualization. Both applications enable the user to access information about an object by snapping a photo of it. We investigate how users would use a photo-based tourist guide in a free exploration setting in general as well as the acceptance/preference of two different ways to visualize results.

In this poster we present findings of a study focusing on touch based interaction using a three display interface design on a mobile phone. We aimed to reveal users' individual preferences and methods for mobile device personalization; to find out to which extent users have already adopted the method of touch based interaction; and finally to investigate users' acceptance of location-based idle screens. Using our new interaction concept for a mobile device, we found out that participants perceive the possibility to personalize their mobile phones as important due to emotional bonding reasons with their mobile device and still the method of touch based interaction has not been fully adopted.

Schrammel, Johann, Kffel, Christina and Tscheligi, Manfred (2009): Personality traits, usage patterns and information disclosure in online communities. In: Proceedings of the HCI09 Conference on People and Computers XXIII 2009. pp. 169-174.

Online communities of different types have become an important part of the daily internet life of many people within the last couple of years. Both research and business have shown interest in studying the possibilities and risks related to these relatively new phenomena. Frequently discussed aspects that are tightly bound to online communities are their implications and effects on privacy issues. Available literature has shown that users generally disclose very much (private) information on such communities, and different factors influencing this behaviour were identified and studied. However, the influence and predictive power of personality traits on information disclosure in online communities has not yet been the subject of analysis. In this paper we report the results of an online survey investigating the relations between personality traits (based on the Fife-Factor Model), usage patterns and information disclosure of participants in different types of online communities.

In this paper we describe adaptations to the classical Extreme Programming (XP) process. The approach described integrates HCI (human computer interaction) instruments. The implemented HCI instruments are: user studies, extreme personas (a variation of the personas approach), usability expert evaluations, usability tests, and automated usability evaluations. By combining XP and UCD (user centered development) processes we take advantages of both approaches.

The power of users playing the roles of authors and editors is undeniable these days [1]. New media, not only the Internet, are enabling people to become active users related to content production and sharing, and in co-creation of User Generated Content (UGC). In particular younger users and heavy users of Internet use networked applications to create and share content [1]. There is a need for UGC applications targeting a broader market, including older users and average Internet users. Today, the knowledge in designing and building for co-creation in networked media is still rather weak. The lack of information about UGC characteristics makes it difficult to expect what kind and amount of content will be produced, and to understand and interpret the reasons why users and user communities arise or fail. A significant effort is currently made by the HCI community in order to support active user involvement into the design and evaluation of networked applications [6]. Non-professional users are encouraged to become active producers and designers themselves [1]. However, there is still the need to explore how to apply and further extend these approaches and methods to better understand, design for and evaluate UGC applications. This SIG will contribute to this discussion by actively involving the audience in UGC creation.

This workshop will discuss the implications of the use of Ambient Intelligence (AmI) for Persuasion. AmI allows surrounding the user with persuasive technology in their everyday life, giving the possibility for persuasive interventions just at the right time and in the right place. The workshop will focus on the potential of Ambient Persuasion for applications in the area of sustainability, health and well-being and related areas. It will also address the need for theoretical foundations and frameworks on which to ground such applications. The use of AmI for persuasion also raises a number of ethical and privacy questions. These issues play an important part in the overall user experience of persuasive AmI applications, where a special focus of this workshop lies.

Proceedings of the Third International Conference on Persuasive Technology - PERSUASIVE 2008 June 4-6, 2008, Oulu, Finland. pp. 128-139.

Poor sitting habits and bad sitting posture are often the cause for musculoskeletal disorders like back pain. Also office employees are affected, because they carry out the majority of their work sitting in front of computers. Therefore we aim at sensitizing and motivating office employees regarding preventive healthcare. We have developed a persuasive interface in form of an interactive picture frame which integrates unobtrusively into the working environment - the perFrame. This frame contains a moving portrait of a person the employee loves or likes. It provides affective feedback in order to persuade employees for better sitting habits while working with a computer. We conducted a preliminary in-situ study, deploying these picture frames on the desktops of eight office employees. The results highlight the employees' acceptance of our application as well as its potential to foster awareness and achieve persuasion regarding healthy behavior in the office.

With our work we refer to value-sensitive and value-centered design approaches to answer the question "why" people join online communities. We conducted qualitative semi-structured Laddering interviews with 21 participants to identify relevant behavior motives for the use of online communities. We identified friendship, self-reflection and information purposes as the most relevant motives. Further, we demonstrate that in the users' experience online communities serve as information pools of social networks used for self-identification and self-reflection.

Interactive TV (iTV) will only succeed if user-centered solutions are provided. Despite an increasing focus on the home environment within the human-computer interaction field, there is still a lack of studies of the context home and empirical data on users' domestic activities (Blythe, Overbeeke, Monk,&Wright, 2004; Mateas, Salvador, Scholtz,&Sorensen,, O'Brien, Rodden, Rouncefield,&Hughes, 1999). In this article, the results of an ethnographic study conducted during the summer 2005 as part of a field trial on iTV in the country of Salzburg, Austria, are presented. The research aim was to gain a deeper understanding of selected household types and household members, their daily habits and social background, their TV viewing behavior and experiences, and expectations on iTV. Within the research, patterns of what people do, how existing technologies facilitate their daily activities, what meanings people connect with the TV, and how iTV services can support people at home could be identified. The findings of this study and the lessons learned from the usability study during the first field trial (Bernhaupt, Ploderer,&Tscheligi, 2005) guided the design and development of the iTV services for the second field trial in spring 2006.

This paper describes the results of three studies investigating an embodied agent that supports its interaction with the user by gazing at corresponding objects within its close environment. Three experiments were conducted in order to research whether users can detect an agent's line of sight, whether the agent's gaze direction can help to guide the users' attention towards designated locations and whether such a setup can be used to improve realistic interaction situations. The results show that a) users can detect the agent's gaze direction quickly (within 200 ms) but not very exactly, b) the use of the agent's gaze direction can speed up but also slow down the detection of objects in dependence on their location and c) that the agent's gaze towards corresponding objects during the interaction can have counterproductive effects in realistic settings.

Proceedings of Ambient Intelligence European Conference, AmI 2007 November 7-10, 2007, Darmstadt, Germany. pp. 314-331.

This paper discusses the prototypical implementation of an ambient display and the results of an empirical study in a retail store. It presents the context of shopping as an application area for Ambient Intelligence (AmI) technologies. The prototype consists of an ambient store map that enhances the awareness of customer activity. The results of our study indicate potentials and challenges for an improvement of the shopping experience with AmI technologies. Based on our findings we discuss challenges and future developments for applying AmI technologies to shopping environments.

In this paper, we describe user experiences with a system equipped with cognitive vision that interacts with the user in the context of personal assistance in the office. A cognitive vision computer can see the user and user responses and react to situations that happen in the environment, crossing the boundary between the virtual and the physical world. How should such a seeing computer interact with its users? Three different interface styles -- a traditional GUI, a cartoon-like embodied agent and a realistic embodied agent -- are tested in two tasks where users are actively observed by a (simulated) cognitive vision system. The system assists them in problem solving. Both the non-embodied and the embodied interaction styles offer the user certain advantages and the pros and cons based on the experiment results are discussed in terms of performance, intelligence, trust, comfort, and social presence.

The optimal way to structure information in hierarchies has occupied researchers for at least two decades. In the last few years, mobile devices added new challenges to this research: the limited screen size, navigation methods and data transfer rates make the search for the optimal information structure even more complex. In this paper an experiment is presented that investigates the usability of 4 different information hierarchies (4{sup:6}, 8{sup:4}, 16{sup:3} and 64{sup:2}) on three mobile devices. It turns out that the narrow hierarchies (4{sup:6} and 8{sup:4}) perform better than the broader hierarchies on the three devices. The experiment was repeated on two more occasions with the same participants to test expertise effects; the preference for narrow hierarchies did not change over the three occasions.

This course addresses strategic and organisational aspects of user experience work in companies, based on experiences in the mobile service industry. It focuses on the question of how to successfully set-up a Corporate User Experience Team in the areas of conflict between top management, marketing, sales, IT, customer service, and product development. Besides the presentation of general motivations and drivers for corporate user experience work and several concepts for doing so, the course in particular represents the authors' experiences in setting-up such a team, discusses key success factors, and the role of selected strategic concepts (ROI, BSC). The organisers will provide an insight into the institutionalization within Austria's largest telecom&mobile service providing company - mobilkom austria. The tutorial provides attendees with the information required in order to be successful in establishing user experience work, and with insights and ideas for strategic positioning.

Many different kinds of context aware systems have been proposed in the domain of mobile systems. So there are many application concepts available which are based some form of context parameters. However, there is additional potential available. In our belief, the truly novel systems that are using context as a major enabler are just appearing. There are now improved platforms for mobile context applications - how to use them to their full potential? The outcome of the workshop on Innovative Mobile Applications of Context (IMAC) will be a set of promising application concepts and scenarios with a solid understanding of the technical feasibility as well as requirements towards enabling context parameters.

The aim of this paper is to propose design principles for ambient intelligence (AmI) environments. The question we are investigating is how these environments can be designed to support a group to be able to carry out common goal-oriented activities. The approach we are taking in answering this question is informed by the concept of collective intelligence (CI). We are applying the concept of CI to AmI as we have found it works well in biological and social systems. Examples from nature demonstrate the power of CI stimulated by implicit cues in the environment. We use these examples to derive design principles for AmI environments. By applying these design principles to a concrete scenario, we are able to propose ways to help decrease environmental pollution within urban areas.

This paper describes the development of a new model of agent emotion elicitation called Nemesys. It enhances interfaces with emotional and social information. Nemesys is based on an artificial neural network and is able to learn six basic emotional states. The elicitation of emotions is based on models drawn from the state of the art in modeling emotions in the field of psychology. Further the described framework includes the Five-Factor Model of Personality to represent different agent personalities. Nemesys (called after Nemesis, the Greek goddess of righteous anger) is designed to perform in various types of interfaces. The usage of Nemesys is presented with an application scenario employing a commercial 3D game-engine. Additionally a critical review of the current elicitation behavior of Nemesys is presented and discussed.

In: Proceedings of 7th conference on Human-computer interaction with mobile devices and services 2005. pp. 287-290.

Navigation aids based on landmarks have been successfully investigated over the last years. There seems to be little doubt that navigation systems using landmarks clearly outperform those systems, relying only on distance specifications. Little, however, is known about the optimal selection of landmarks that are used to lead the user through an environment. This paper presents five methods to select landmarks that are visually and semantically distinguishable and which are suited to lead the user to his/her goal. The paper also discusses the lessons learned from the application of these methods. It shows the results that can be expected and it highlights also their possible traps and drawbacks.

Tscheligi, Manfred (2005): Context in mobile HCI. In: Proceedings of 7th conference on Human-computer interaction with mobile devices and services 2005. pp. 355-356.

This workshop aims to explore recent research and findings on context in the face of mobile HCI. The goal of the workshop is to raise discussions on the topics, and leverage a share of experiences among people addressing the aspects from different perspectives, e.g. human-computer interaction, ubiquitous computing, ambient environments, psychology, cognitive science, communication science, design, etc.

Proceedings of the ACM CHI 2000 Human Factors in Computing Systems Conference April 1-6, 2000, The Hague, The Netherlands. pp. 548-555.

Increasing use of mobile phones in leisure and communication with digital images are important and current issues in the field of telecommunications. However, little is known about how images would be used in leisure related communication. According to our experience field trials are the best way of studying it. In this paper, we describe a field-trial case study of leisure related communication with digital images. Moreover, we discuss the advantages of conducting field trials as part of product concept design process.

INTERACT 90 - 3rd IFIP International Conference on Human-Computer Interaction August 27-31, 1990, Cambridge, UK. pp. 469-472.

Design alternatives for modern object based user interfaces are presented trying to reach a second generation of enjoyable graphical user interfaces. The objects are designed following the real life paradigm, yielding to intuitive human computer associations. Objects are parameterized to give the user some possibilities to adjust his operating environment, according to his special needs. Menus, highly used in traditional user interfaces, are superfluous in our introduced system.
