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(More)
Implicit in much research and application development for mobile phones is the assumption that the mobile phone is a suitable proxy for its owner's 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(More)
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(More)
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(More)
Conducting user-centered design is a primary challenge in ubiquitous computing. Two kinds of prototyping techniques can be particularly effective for developing mobile and ubiquitous computing applications: compound prototypes and situated experience prototypes. Compound prototypes combine the final product's user interface (UI) with a computational(More)
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(More)

In this paper, we explain how our research on applications for chronic care domain problems has uncovered challenges and opportunities in the design and development of collaborative applications. Specifically, we discuss projects focused on care of the elderly, children with special needs, and individuals with diabetes.
Parenting is always demanding, but families coping with neurodevelopmental disorders, such as ADHD, experience unique challenges. To address these challenges, research in the area of Parental Behavioral Therapy is accelerating. This type of therapy focuses on behavioral strategies that, if practiced regularly, can have a positive impact on the child's(More)
