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. Available online
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, Özge, Höller, 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. Available online
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.

Weiss, Astrid, Wurhofer, Daniela, Lankes, Michael and Tscheligi, Manfred (2009): Autonomous vs. tele-operated: how people perceive human-robot collaboration with hrp-2. In: Proceedings of the 4th ACM/IEEE International Conference on Human Robot Interaction 2009. pp. 257-258. Available online
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.

In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2151-2158. Available online
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.

Obrist, Marianna, Geerts, David, Brandtzæg, Petter Bae and Tscheligi, Manfred (2008): Design for creating, uploading and sharing user generated content. In: Proceedings of ACM CHI 2008 Conference on Human Factors in Computing Systems April 5-10, 2008. pp. 2391-2394. Available online
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.

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.

Obrist, Marianna, Bernhaupt, Regina and Tscheligi, Manfred (2008): Interactive TV for the Home: An Ethnographic Study on Users' Requirements and Experiences. In International Journal of Human-Computer Interaction, 24 (2) pp. 174-196
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.

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.

In: Proceedings of 8th conference on Human-computer interaction with mobile devices and services 2006. pp. 285-286. Available online
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. Available online
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.

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.

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.
