The DxD lab folks are interested in designing, developing, and evaluating applications of computing technology that promotes physical and mental health. We design mobile and social technologies that enable collecting insightful data from our everyday lives and visualizing data with the goal of helping with self-reflection. We also work on the design of crowd-powered services towards the accessibility and education. Our lab functions as a DIY environment, a place to run studies of our new technologies, and a workspace for collaboration among graduate and undergraduate students.

Mindfulness + Interactive Technology

We introduce Calm Station, an interactive perpetual desk object that reduces digital distractions. Calm Station is designed to convey daily notifications with abstract, poetic movements. It allows users to remain focused while doing desk work, reading, or relaxing by transferring distracting notifications.

We introduce MindTracker, an approach that asks participants to express their emotions using a tangible material, clay. MindTracker’s data collection and reflection has similar properties to expressive therapy, which is an instrument used to improve mental health.

ALLSUB is a crowdsourcing platform which generates subtitles in order to produce accessible movies for people with hearing impairments. ALLSUB enables web users to produce descriptive captions of short video clips. The ultimate goal of this project is to provide opportunities for people with hearing impairment to access much more movies without barriers by gathering works from the community.

Medical Crowdfunding Study

Crowdfunding sites are already recognized as platforms that help patients receive financial support from their distributed social networks online. Through an extensive collaboration with researchers at UIUC, we demonstrated that not only do online medical crowdfunding sites facilitate monetary donations, they also harness concrete types of assistance (e.g., babysitting, meal preparation, hospital visit) in a timely manner.

Autism + Social Networks

We explore using communication circle on a social network site, GroupMe, for young adults with autism. We provide implications for social intervention and technical design to support the independence of the special needs population.

We develop and evaluate a concept of “Social Mirror”, a social networking system that supports on-demand connections to a trusted network such as family and friends intended as an aid for success in everyday life.
