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)
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)
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)
BACKGROUND Prior research has critiqued the lack of attention to the stressors associated with dementia related dressing issues, stigmatizing patient clothing, and wearable technology challenges. This paper describes the conceptual development and feasibility testing of an innovative 'smart dresser' context aware affective system (DRESS) to enable dressing(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)
Analysis of students’ log data to understand their process as they solve problems is an essential part of educational technology research. Models of correct and buggy student behavior can be generated from this log data and used as a basis for intelligent feedback. Another important technique for understanding problem-solving process is video protocol(More)
This paper presents a new technical losses reduction model in an electrical energy distribution system by using network reconfiguration technique. First-order logic is used as the model specification language. This specification is easily translated into programmable sentences in the CCP (Concurrent Constraint Programming) paradigm. Unlike other existing(More)
The majority of educational software is designed for traditional computers, which allow little opportunity for physical manipulation of an environment. Tangible Activities for Geometry (TAG) provides students a tangible learning environment. Currently, however, TAG does not employ adaptive scaffolding techniques. Accordingly, we describe how scaffolding(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)
