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)
vSked is an interactive and collaborative assistive technology for students with autism, combining visual schedules, choice boards, and a token-based reward system into an integrated classroom system. In this paper, we present the results of a study of three deployments of vSked over the course of a year in two autism classrooms. The results of our study(More)
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(More)
Upon leaving the hospital, parents of high-risk infants experience a variety of challenges in providing care at home. In this work, we present results from a qualitative study to understand the role of social interaction and information-sharing surrounding high-risk infants among both home caregivers and health professionals. These results demonstrate(More)
Collaborative brainstorming can be a challenging but important part of creative group problem solving. Mind-mapping has the potential to enhance the brainstorming process but has its own challenges when used in a group. We introduce GroupMind, a collaborative mind-mapping tool that addresses these challenges and opens new opportunities for creative(More)
Preterm infants have significantly higher rates of functional limitations and are at risk for delays in cognitive, motor, and other skills. Through high-risk infant follow-up (HRIF) programs and other early detection methods, these delays and complications can be reduced. However, these interventions require substantial resources and can create extra burden(More)
Based on an 18-month qualitative study that included the creation and testing of design considerations and a prototype location-based information system (LBIS), this research provides empirical insight into the daily practices of a wide variety of individuals working to address food insecurity in one U.S. county. Qualitative fieldwork reveals that nonprofit(More)
In this article, we describe the design process and principles used in the development of Estrellita, a tool to support parents of preterm infants to track health data. We tested Estrellita in the homes of seven families for 4 months while following seven additional families without Estrellita. The feedback from this trial, including in-depth interviews,(More)
Medical research suggests that avoiding lengthy periods of physical inactivity can have significant health benefits. The pervasive nature of mobile phones increasingly allows individuals to track and measure their own physical activity thus creating opportunities for them to reflect on their behavior and make informed changes. In this work, we investigated(More)
