The relationship of action research to human-computer interaction

Alongside the growing interest within HCI, and arguably computing more generally, in conducting research that has substantial societal benefits, there is a need for new ways to think about and to articulate the challenges of these engaged research projects as well as their results. Action Research (AR) is a class of methods and approaches for conducting democratic and collaborative research with community partners. AR has evolved over the last several decades and offers HCI researchers theoretical lenses, methodological approaches, and pragmatic guidance for conducting socially relevant, collaborative, and engaged research. In this article, I describe the historical context and origins of AR, the scientifically rigorous practice of conducting and evaluating AR projects, and the ways in which AR might meaningfully be applied to HCI research.

Interactive visual supports for children with autism

Interventions to support children with autism often include the use of visual supports, which are cognitive tools to enable learning and the production of language. Although visual supports are effective in helping to diminish many of the challenges of autism, they are difficult and time-consuming to create, distribute, and use. In this paper, we present the results of a qualitative study focused on uncovering design guidelines for interactive visual supports that would address the many challenges inherent to current tools and practices. We present three prototype systems that address these design challenges with the use of large group displays, mobile personal devices, and personal recording technologies. We also describe the interventions associated with these prototypes along with the results from two focus group discussions around the interventions. We present further design guidance for visual supports and discuss tensions inherent to their design.

Beyond the Grave: Facebook as a Site for the Expansion of Death and Mourning

Online identities survive the deaths of those they represent, leaving friends and families to struggle with the appropriate ways to incorporate these identities into the practices of grief and mourning, raising important questions. How are practices of online memorialization connected to conventional rituals of grief and mourning? What is the role of online digital identity postmortem? How do trajectories of death and dying incorporate both online and offline concerns? Based on our qualitative study of death and mourning online, we identify the way that social networking sites enable expansion—temporally, spatially, and socially—of public mourning. Rather than looking at online practices as disruptions of traditional practices of grief and memorialization, we examine them as new sites in which public mourning takes place.

Pervasive Computing and Autism: Assisting Caregivers of Children with Special Needs

Pervasive computing technologies can support children with autism and their caregivers. Work continues on systems that aid record collection and analysis, decision making, communication, and assessment of childrens internal states

Farther than you may think: an empirical investigation of the proximity of users to their mobile phones

Implicit in much research and application development for mobile phones is the assumption that the mobile phone is a suitable proxy for its owners location. We report an in-depth empirical investigation of this assumption in which we measured proximity of the phone to its owner over several weeks of continual observation. Our findings, summarizing results over 16 different subjects of a variety of ages and occupations, establish baseline statistics for the proximity relationship in a typical US metropolitan market. Supplemental interviews help us to establish reasons why the phone and owner are separated, leading to guidelines for developing mobile phone applications that can be smart with respect to the proximity assumption. We show it is possible to predict the proximity relationship with 86% confidence using simple parameters of the phone, such as current cell ID, current date and time, signal status, charger status and ring/vibrate mode.

Storyboarding: an empirical determination of best practices and effective guidelines

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.

vSked: evaluation of a system to support classroom activities for children with autism

Visual schedules--the use of symbols to represent a series of activities or steps--have been successfully used by caregivers to help children with autism to understand, structure, and predict activities in their daily lives. Building from in-depth fieldwork and participatory design sessions, we developed vSked, an interactive and collaborative visual scheduling system designed for elementary school classrooms. We evaluated vSked in situ in one autism-specific classroom over three weeks. In this paper, we present the design principles, technical solution, and results from this successful deployment. Use of vSked resulted in reductions in staff effort required to use visual supports. vSked also resulted in improvements in the perceived quality and quantity of communication and social interactions in the classroom.

Barriers to the adoption and use of personal health record systems

Personal health records (PHR) have enormous potential to improve both documentation of health information and patient care. The adoption of these systems, however, has been relatively slow. In this work, we used a multi-method approach to evaluate PHR systems. We interviewed potential end users---clinicians and patients---and conducted evaluations with patients and caregivers as well as a heuristic evaluation with HCI experts. In these studies, we focused on three PHR systems: Google Health, Microsoft HealthVault, and WorldMedCard. Our results demonstrate that both usability concerns and socio-cultural influences are barriers to PHR adoption and use. In this paper, we present those results as well as reflect on how both PHR designers and developers might address these issues now and throughout the design cycle.

MOSOCO: a mobile assistive tool to support children with autism practicing social skills in real-life situations

MOSOCO is a mobile assistive application that uses augmented reality and the visual supports of a validated curriculum, the Social Compass, to help children with autism practice social skills in real-life situations. In this paper, we present the results of a seven-week deployment study of MOSOCO in a public school in Southern California with both students with autism and neurotypical students. The results of our study demonstrate that MOSOCO facilitates practicing and learning social skills, increases both quantity and quality of social interactions, reduces social and behavioral missteps, and enables the integration of children with autism in social groups of neurotypical children. The findings from this study reveal emergent practices of the uses of mobile assistive technologies in real-life situations.

We will never forget you [online]: an empirical investigation of post-mortem myspace comments

The proliferation of social network sites has resulted in an increasing number of profiles representing deceased users. In this paper, we present the results of a mixed-methods empirical study of 205,068 comments posted to 1,369 MySpace profiles of users who have died. Our results reveal interesting practices surrounding issues of authorship and audience, temporal patterns in posting, and continued social networking with the dead. These results suggest that post-mortem commenting behavior blends memorializing practices with existing practices and communication patterns for social network sites. We conclude by outlining future directions for research and implications for the understanding and use of social network sites in light of a deeper understanding of post-mortem comments.
