Kientz, Julie A., Arriaga, Rosa I. and Abowd, Gregory D. (2009): Baby steps: evaluation of a system to support record-keeping for parents of young children. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 1713-1722. Available online
“Parents of young children often want to keep a variety of records on their children's early years, for the purposes of preservation of memories or at the request of their pediatrician. However, time constraints, motivation, and forgetfulness may hinder their ability to keep consistent records. We developed a system, Baby Steps, which is designed to improve the record-keeping process. In this paper, we present the results of a 3-month deployment study of this technology with 8 families and their pediatricians. The study showed that when compared to a control condition, experimental design features of Baby Steps encouraged parents to more frequently collect and review records, provided higher confidence in reporting, and improved parent-pediatrician communication.”

“Researchers in human-computer interaction and allied fields are increasingly interested in using new sensing capabilities to create context-aware interfaces and devices for the home. Data from sensors worn on the body or installed in an environment can be used by algorithms to infer what activities the home occupant may be engaged in and enable applications to respond accordingly. This one-day CHI'09 workshop would convene a multidisciplinary group of researchers to discuss strategies for creating community resources that might accelerate research on development of home technologies. In particular, the participants will discuss how to collaboratively gather high quality synchronized data streams from real homes, as well as qualitative material about home occupants and their behaviors. The resultant datasets could facilitate work on context modeling and enable researchers in other areas of HCI to explore contextual factors influencing the use of technology in naturalistic settings. The outcome of the workshop will be a community index of existing shared datasets of home behavior and guidelines for those interested in creating and disseminating new datasets.”

“While supporting family communication has traditionally been a domain of interest for interaction designers, few research initiatives have explicitly investigated remote synchronous communication between children and parents. We discuss the design of the ShareTable, a media space that supports synchronous interaction with children by augmenting videoconferencing with a camera-projector system to allow for shared viewing of physical artifacts. We present an exploratory evaluation of this system, highlighting how such a media space may be used by families for learning and play activities. The ShareTable was positively received by our participants and preferred over standard videoconferencing. Informed by the results of our exploratory evaluation, we discuss the next design iteration of the ShareTable and directions for future investigations in this area.”

“Identifying the function of problem behavior can lead to the development of more effective interventions. One way to identify the function is through functional behavior assessment (FBA). Teachers conduct FBA in schools. However, the task load of recording the data manually is high, and the challenge of accurately identifying antecedents and consequences is significant while interacting with students. These issues often result in imperfect information capture. CareLog allows teachers more easily to conduct FBAs and enhances the capture of relevant information. In this paper, we describe the design process that led to five design principles that governed the development of CareLog. We present results from a five-month, quasi-controlled study aimed at validating those design principles. We reflect on how various constraints imposed by special education settings impact the design and evaluation process for HCI practitioners and researchers.”

“In this paper, we present the design process for developing a technology to support therapists for children with autism. To learn about the domain for which we were designing, one researcher became trained as a therapist and worked as one part time for over 10 months. This case study outlines the process by which the researcher was trained, the ways in which it was helpful in the design and evaluation of a technology system, and the aspects of the experience that we feel led to a better and more successful design.”

“Within a group of peers, it is often useful or interesting to know whether someone in the group has gone to bed or whether they have awakened in the morning. This information, naturally integrated as a peripheral augmentation of an alarm clock, allows people to know whether it is appropriate to make a call or feel more connected with someone living remotely. In this paper, we present the design and evaluation of such an alarm clock, the BuddyClock, and describe how it enables users in a small social network to automatically share information about their sleeping behaviors with one another. Through 3-6 week deployment studies of this technology with five different social networks, we found that the alarm clock affected participant behaviors and allowed them to feel more connected to those with whom they shared their sleeping behaviors.”

“In this paper, we describe the design considerations and implementation of the Child'sPlay system, a technology for supporting the automatic recording, recognition, and quantification of a child's object play behaviors for retrospective analysis. Our prototype system consists of six varieties of toys augmented with wireless sensing capabilities and a mobile computing platform which uses statistical pattern recognition techniques to automatically classify sensed play behaviors. This paper discusses our choices in toy design both in form factor as well as sensing capabilities. In addition, we also describe the play activities the system supports and provide an overview of our initial recognition algorithms.”

Iachello, Giovanni and Abowd, Gregory D. (2008): From privacy methods to a privacy toolbox: Evaluation shows that heuristics are complementary. In ACM Transactions on Computer-Human Interaction, 15 (2) p. 8
“We describe the two-year-long development and evaluation of the Proportionality Method, a design method intended to aid HCI practitioners in designing advanced IT applications with complex privacy implications. The method is inspired by Data Protection Authorities' (DPA) and Courts' practice and proposes to balance the impact on privacy of IT applications with their usefulness. We discuss the results of an evaluation of the design method to verify its usability, usefulness and effectiveness vis-a-vis other design methods proposed in the HCI literature to address similar issues. Results suggest that different design methods for privacy highlight different sets of issues and a combination of methods should be employed in a comprehensive design process. We propose to judge design methods based on their overall quantitative and qualitative merits, including the type of application and technology for which they are most fit and their methodological approach. We finally propose to develop a privacy toolbox, that is, a set of heuristic methods that designers can choose from with knowledge and understanding of their relative advantages and limitations.”

“A number of prototype meeting capture applications have been created in the past decade, yet relatively little research has focused on the review and long-term use of real captured meeting information. To that end, we have implemented a system called TeamSpace for capturing and reviewing general meetings. In this article, we describe the long-term deployment of TeamSpace to a university research group, along with a pseudo-controlled study involving the same group of users and their meetings. We gained a detailed understanding of the behavioral patterns involved in reviewing meeting content and how to improve on the experience. Our evaluations also demonstrate several of the barriers and challenges in realizing the potential benefits of meeting capture.”

In: Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007. pp. 1351-1360. Available online
“From birth through age five, children undergo rapid development and learn skills that will influence them their entire lives. Regular visits to the pediatrician and detailed record-keeping can ensure that children are progressing and can identify early warning signs of developmental delay or disability. However, new parents are often overwhelmed with new responsibilities, and we believe there is an opportunity for computing technology to assist in this process. In this paper, we present a qualitative study aimed at uncovering some specific needs for record-keeping and analysis for new parents and their network of caregivers. Through interviews and focus groups, we have confirmed assumptions about the rationales parents have and the functions required for using technology for record-keeping. We also identify new themes, potential prototypes, and design guidelines for this domain.”

“We describe a unique form of hands-free interaction that can be implemented on most commodity computing platforms. Our approach supports blowing at a laptop or computer screen to directly control certain interactive applications. Localization estimates are produced in real-time to determine where on the screen the person is blowing. Our approach relies solely on a single microphone, such as those already embedded in a standard laptop or one placed near a computer monitor, which makes our approach very cost-effective and easy-to-deploy. We show example interaction techniques that leverage this approach.”

“Evidence-based care is an increasingly popular process for long term diagnosis and monitoring of education and healthcare disabilities. Because this evidence must also be collected in everyday life, it is a technique that can greatly benefit from automated capture technologies. These solutions, however, can raise significant concerns about privacy, control, and surveillance. In this paper, we present an analysis of these concerns with regard to evidence-based care. This analysis underscores the need to consider community-based risk and reward analyses in addition to the traditionally used analyses for individual users when designing socially appropriate technologies.”

In: Proceedings of ACM CHI 2006 Conference on Human Factors in Computing Systems 2006. pp. 1009-1018. Available online
“We developed an inquiry technique, which we called "paratype," based on experience prototyping and event-contingent experience sampling, to survey people in real-life situations about ubiquitous computing (ubicomp) technology. We used this tool to probe the opinions of the conversation partners of users of the Personal Audio Loop, a memory aid that can have a strong impact on their privacy. We present the findings of this study and their implications, specifically the need to broaden public awareness of ubicomp applications and the unfitness of traditional data protection guidelines for tackling the privacy issues of many ubicomp applications. We also point out benefits and methodological issues of paratypes and discuss why they are particularly fit for studying certain classes of mobile and ubicomp applications.”

Available online
“Finding lost items is a common problem for the visually impaired and is something that computing technology can help alleviate. In this paper, we present the design and evaluation of a mobile solution, called FETCH, for allowing the visually impaired to track and locate objects they lose frequently but for which they do not have a specific strategy for tracking. FETCH uses devices the user already owns, such as their cell phone or laptop, to locate objects around their house. Results from a focus group with visually impaired users informed the design of the system. We then studied the usability of a laptop solution in a laboratory study and studied the usability and usefulness of the system through a one-month deployment and diary study. These studies demonstrate that FETCH is usable and useful, but there is still room for improvement.”

“Teams of therapists often provide targeted interventions for children with developmental disabilities. A common practice in these cases is one-on-one interaction between a therapist and the child together with occasional group meetings of the therapists to discuss progress and make informed decisions to modify the intervention plan. We designed a system called Abaris to support this form of collaborative decision-making for a particular intervention popular in the treatment of children with autism. Our system allows for the simultaneous use of trending data across therapy sessions and detailed session data that is automatically integrated with highly indexed video. We discuss the impact this system had on the team dynamics, the amount of collaboration, and the effect it had on the team using evidence and videos to make decisions about the care of the child.”

“Storyboarding is a common technique in HCI and design for demonstrating system interfaces and contexts of use. Despite its recognized benefits, novice designers still encounter challenges in the creation of storyboards. Furthermore, as computing becomes increasingly integrated into the environment, blurring the distinction between the system and its surrounding context, it is imperative to depict context explicitly in storyboards. In this paper, we present two formative studies designed to uncover the important elements of storyboards. These elements include the use of text, inclusion of people, level of detail, number of panels, and representation of the passage of time. We further present an empirical study to assess the effects of these elements on the understanding and enjoyment of storyboard consumers. Finally, we demonstrate how these guidelines were successfully used in an undergraduate HCI class.”

“Recent research suggests design pre-patterns, structured collections of evidence-based research and design knowledge, provide a useful resource for design activities in emerging application domains. This paper extends previous research by exploring the impact of pre-patterns and tools to support pre-pattern exploration for the domain of ubiquitous computing in the home. We conducted an empirical study of 44 designers engaged in a two hour concentrated brainstorming and design task for the home of the future. Our results show pre-patterns are an easily adopted resource for designers that can impact even the earliest of design activities. We also provide insights for future development of pre-patterns based on designer feedback.”

“Researchers have been exploring the ubiquitous capture and access of meetings for the past decade. Yet, few evaluations of these systems have demonstrated the benefits from using recorded meeting information. We are exploring the capture and access of Knowledge Acquisition sessions, discussions to understand the problems and requirements that feed systems development. In this paper, we evaluate the use of these recordings in creating a requirements document. We show that recordings of discussions will not be utilized without appropriate structure and indexing. Our study demonstrates how captured information can be used in such a task and the potential benefits that use may afford.”

“We argue that an analytic proportionality assessment balancing usefulness and burden on individual or group privacy must be conducted throughout the design process to create acceptable ubiquitous computing (ubicomp) applications and services. We introduce the principle of proportionality, which originates within the legal and data protection communities. Inspired by this principle, we develop a design method for ubicomp applications, based on our own experience, and aimed at HCI practitioners and designers. We discuss the method in relation to real-world examples, user inquiry techniques and requirements engineering models. Finally, we report a sample application of the method, involving a ubiquitous, personal memory aid tool.”

“Diagnosis, treatment, and monitoring of interventions for children with autism can profit most when caregivers have substantial amounts of data they can easily record and review as evidence of specific observed behaviors over time. Through our work with one prototype system and interviews with caregivers, we have recognized the importance of socially appropriate ways to add rich data to the information recorded by caregivers. Analysts must be able to view incidents as they occurred without unnecessarily burdening caregivers and other children with always-on recording of data about them. In this paper, we introduce experience buffers, a collection of capture services embedded in an environment that, though always on and available, require explicit user action to store an experience.. This creates a way to balance the social, technical, and practical concerns of capture applications.”

“A variety of ubiquitous computing systems have been built to automatically capture everyday activities in a number of domains. Many capture systems record streams of information that structure and form indices into the recording, providing users easy access to portions of interest. But this is challenging in very unstructured situations or unpredictable environments. In this paper, we explore introducing structure into the activity through the use of an artificial, unrelated, peripheral stream of information. We investigate the feasibility of this idea by integrating a stream of images into an existing meeting capture system. Our study suggests that this technique may be used effectively in some situations, and reveals similar methods of capturing and using indices that could be explored.”

“Rear projection of large-scale upright displays is often preferred over front projection because of the lack of shadows that occlude the projected image. However, rear projection is not always a feasible option for space and cost reasons. Recent research suggests that many of the desirable features of rear projection, in particular shadow elimination, can be reproduced using new front projection techniques. We report on the results of an empirical study comparing two new projection techniques with traditional rear projection and front projection.”

“In this article, we describe the design process of Reno, a location-enhanced, mobile coordination tool and person finder. The design process included three field experiments: a formative Experience Sampling Method (ESM) study, a pilot deployment and an extended user study. These studies were targeted at the significant personal security, privacy and data protection concerns caused by this application. We distill this experience into a small set of guidelines for designers of social mobile applications and show how these guidelines can be applied to a different application, called Boise. These guidelines cover issues pertaining to personal boundary definition, control, deception and denial, and group vs. individual communication. We also report on lessons learned from our evaluation experience, which might help practitioners in designing novel mobile applications, including the choice and characterization of users for testing security and privacy features of designs, the length of learning curves and their effect on evaluation and the impact of peculiar deployment circumstances on the results of these finely tuned user studies.”

“Powerful mobile devices with minimal I/O capabilities increase the likelihood that we will want to annex these devices to I/O resources we encounter in the local environment. This opportunistic annexing will require authentication. We present a sensor-based authentication mechanism for mobile devices that relies on physical possession instead of knowledge to setup the initial connection to a public terminal. Our solution provides a simple mechanism for shaking a device to authenticate with the public infrastructure, making few assumptions about the surrounding infrastructure while also maintaining a reasonable level of security.”

“A number of studies have explored issues of interruption and availability in workplace environments, but few have examined how attitudes toward availability play out in home life. In this paper, we begin to explore factors in the home that might be useful for signaling availability to close friends and family. In particular, we use the Experience Sampling Method (ESM) to measure subjects' current activities and self-reported availability to interruption. Based on follow-up interviews, we develop a number of hypotheses that we test through a hierarchical linear regression analysis. Results indicate that individual differences, certain home locations, and leisure activities play an important role in determining patterns of availability. This study has implications for the development of CSCW systems with automatic sensing of activity to deal with interruption and activity recognition both inside and out of the home.”

“Many context-aware services make the assumption that the context they use is
completely accurate. However, in reality, both sensed and interpreted context
is often ambiguous. A challenge facing the development of realistic and
deployable context-aware services, therefore, is the ability to handle
ambiguous context. In this paper, we describe an architecture that supports the
building of context-aware services that assume context is ambiguous and allows
for mediation of ambiguity by mobile users in aware environments. We illustrate
the use of our architecture and evaluate it through three example context-aware
services, a word predictor system, an In/Out Board, and a reminder tool.”

“Computing devices and applications are now used beyond the desktop, in diverse environments, and this trend toward ubiquitous computing is accelerating. One challenge that remains in this emerging research field is the ability to enhance the behavior of any application by informing it of the context of its use. By context, we refer to any information that characterizes a situation related to the interaction between humans, applications, and the surrounding environment. Context-aware applications promise richer and easier interaction, but the current state of research in this field is still far removed from that vision. This is due to 3 main problems: (a) the notion of context is still ill defined, (b) there is a lack of conceptual models and methods to help drive the design of context-aware applications, and (c) no tools are available to jump-start the development of context-aware applications. In this anchor article, we address these 3 problems in turn. We first define context, identify categories of contextual information, and characterize context-aware application behavior. Though the full impact of context-aware computing requires understanding very subtle and high-level notions of context, we are focusing our efforts on the pieces of context that can be inferred automatically from sensors in a physical environment. We then present a conceptual framework that separates the acquisition and representation of context from the delivery and reaction to context by a context-aware application. We have built a toolkit, the Context Toolkit, that instantiates this conceptual framework and supports the rapid development of a rich space of context-aware applications. We illustrate the usefulness of the conceptual framework by describing a number of context-aware applications that have been prototyped using the Context Toolkit. We also demonstrate how such a framework can support the investigation of important research challenges in the area of context-aware computing.”

“The Web is used for many purposes in education, such as the publication of course management information, centralized distribution of course materials, and supporting on-line discussions between instructors and students or among the students themselves. Leveraging off the Web for educational activities both inside and outside the classroom produces a dynamic educational repository. In this paper, we present work that explicitly attempts to connect in-class activity, in the form of multimedia, Web-accessible captured lectures, with collaborative discussion spaces. Flexible and dynamic interfaces for the captured lectures and the discussion spaces are presented, as well as specialized interfaces that connect the two. We discuss our experience in a recent course taught using this integrated and dynamic educational repository and explain how our experience has lead to some solutions for visualizing the changes that occur over this rich space.”

“Interfaces based on recognition technologies are used extensively in both the commercial and research worlds. But recognizers are still error-prone, and this results in human performance problems, brittle dialogues, and other barriers to acceptance and utility of recognition systems. Interface techniques specialized to recognition systems can help reduce the burden of recognition errors, but building these interfaces depends on knowledge about the ambiguity inherent in recognition. We have extended a user interface toolkit in order to model and to provide structured support for ambiguity at the input event level. This makes it possible to build re-usable interface components for resolving ambiguity and dealing with recognition errors. These interfaces can help to reduce the negative effects of recognition errors. By providing these components at a toolkit level, we make it easier for application writers to provide good support for error handling. Further, with this robust support, we are able to explore new types of interfaces for resolving a more varied range of ambiguity.”

“The proliferation of computing into the physical world promises more than the ubiquitous availability of computing infrastructure; it suggest new paradigms of interaction inspired by constant access to information and computational capabilities. For the past decade, application-driven research on ubiquitous computing (ubicomp) has pushed three interaction themes: natural interfaces, context-aware applications, and automated capture and access. To chart a course for future research in ubiquitous computing, we review the accomplishments of these efforts and point to remaining research challenges. Research in ubiquitous computing implicitly requires addressing some notion of scale, whether in the number and type of devices, the physical space of distributed computing, or the number of people using a system. We posit a new area of applications research, everyday computing, focussed on scaling interaction with respect to time. Just as pushing the availability of computing away from the traditional desktop fundamentally changes the relationship between humans and computers, providing continuous interaction moves computing from a localized tool to a constant companion. Designing for continuous interaction requires addressing interruption and resumption of interaction, representing passages of time and providing associative storage models. Inherent in all of these interaction themes are difficult issues in the social implications of ubiquitous computing and the challenges of evaluating ubiquitous computing research. Although cumulative experience points to lessons in privacy, security, visibility, and control, there are no simple guidelines for steering research efforts. Akin to any efforts involving new technologies, evaluation strategies form a spectrum from technology feasibility efforts to long-term use studies -- but a user-centric perspective is always possible and necessary.”

“Context-enabled applications are just emerging and promise richer interaction by taking environmental context into account. However, they are difficult to build due to their distributed nature and the use of unconventional sensors. The concepts of toolkits and widget libraries in graphical user interfaces has been tremendously successful, allowing programmers to leverage off existing building blocks to build interactive systems more easily. We introduce the concept of context widgets that mediate between the environment and the application in the same way graphical widgets mediate between the user and the application. We illustrate the concept of context widgets with the beginnings of a widget library we have developed for sensing presence, identity and activity of people and things. We assess the success of our approach with two example context-enabled applications we have built and an existing application to which we have added context-sensing capabilities.”

“The paper describes how the identification of 'status-status mappings' early in the specification and design of an interactive system can highlight potential temporal problems in the interface. These problems arise because without infinitely fast computation and communication, any constraints between status in the interface are bound to be violated some of the time. This violation will at best be a slight lag between the source of a change and its display and at worst may lead to inconsistency between parts of the interface. We identify the ways in which status-status mappings are violated and the way in which they are mediated by events in the implementation of a system. This enables the designer to control the eventual behaviour of the system and avoid the worst pitfalls.”

“A number of notations exist by which a designer can specify the behavior of a human-computer interface in relatively formal terms. In this paper we show how many of the dialogue specifications described using these notations are amenable to automated analysis to detect potential problems such as user actions that are never enabled or have effects that are hard to reverse. In many situations, a dialogue specification can be thought of as a finite state machine in which the transition between states is signalled as an event from the user or system. The trouble with this state transition model is that states quickly multiply presenting two problems to the analyst: (i) how to easily describe all of the possible dialogue states and state transitions; and (ii) how to analyze a very large STN. This paper reviews possible solutions to both of these problems. A tabular interface to Olsen's Propositional Production System is described and goes some way towards solving the descriptive problem. This representation is also useful for simulating requirements scenarios in a validation exercise. For the analytic problem, we make use of finite state model checking technology that allows for automated analysis of very large state machines. We demonstrate how eight categories of dialogue verification properties can be analyzed with this approach. Together, dialogue simulation and automated verification leads to a more complete analytic framework for dialogue development.”

“Successful interface design respects constraints stemming from a number of diverse domains analysed by different disciplines. Modelling techniques exist within the individual disciplines, but there is a need for ways to weave together different techniques to provide an integrated analysis of interface design issues from multiple perspectives. We illustrate the relations and interplay between six different modelling techniques -- two for system modelling, two for user modelling, one for interaction modelling, and one for design modelling -- applied to a shared design scenario concerning the provision of an Undo facility for a collaborative editor. The resulting multi-perspective analysis provides a depth of understanding and a breadth of scope beyond what can be achieved by any one technique alone.”

“The problems associated with the provision of an undo support facility in the context of a synchronous shared or group editor are investigated. Previous work on the development of formal models of 'undo' has been restricted to single user systems and has focused on the functionality of undo, as opposed to discussing the support that users require from any error recovery facility. Motivated by new issues that arise in the context of computer supported co-operative work, the authors aim to integrate formal modelling of undo with an analysis of how users understand undo facilities. Together, these combined perspectives of the system and user lead to concrete design advice for implementing an undo facility. The special issues that arise in the context of shared undo also shed light on the emphasis that should be placed on single user undo. In particular, the authors regard undo not as a system command to be implemented, but as a user intention to be supported by the system.”

These notions of distance can be formalised to give an understandable quantitative approach required for principled design and analysis.”

“In this paper we extend the theory of communicating interactive processes based on the formalisms of CSP and Z first presented by Sufrin and He. We then use this theory to show how specifications of complex interactive systems are composed from smaller and simpler components. The theory provides a formal foundation for the investigation of multiagent models and allows the precise formulation of design principles for the development of interactive systems. We view an interactive system as a closed collection of communicating interactive processes, or agents. An agent can represent both an application and its users. We develop an example of a mouse and keyboard input to a simple display manager. This will serve as a small but realistic example to explain the features of the model.”
