Due to its high sensitivity and conductivity, electrotactile stimulation (ETS) on the tongue has proven to be a useful and technically convenient tool to substitute and/or augment sensory capabilities. However, most of its applications have only provided spatial attributes and little is known about (a) the ability of the tongue's sensory system to process(More)
HCI researchers and technologists have heralded multitouch interaction as the technology to drive computing systems into the future. However, as we move towards a world where interaction is based on human body movements that are not well documented or studied, we face a serious and a grave risk of creating technology and systems that may lead to(More)
As technology is increasingly integrated into the classroom, understanding the facilitators and barriers for deployment becomes an important part of the process. While systems that employ traditional WIMP-based interfaces have a well-established body of work describing their integration into classroom environments, more novel technologies generally lack(More)
To date, the majority of learning technologies only afford virtual interactions on desktops or tablets, despite evidence that students learn through physical manipulation of their environment. We implemented a tangible system that allows students to solve coordinate geometry problems by interacting in a physical space with digitally augmented devices, using(More)
OBJECTIVE To gain an understanding of Latino/Hispanic caregivers' dementia-related dressing issues, their impressions of using a "smart" context-aware dresser to coach dressing, and recommendations to improve its acceptability. METHOD The same Latina moderator conducted all the caregiver focus groups. She followed a semi-structured interview guide that(More)
