In this paper we explore the potential and limitations of vibrotactile displays in practical wearable applications, by comparing users' detection rate and response time to stimuli applied across the body in varied conditions. We examined which body locations are more sensitive to vibrations and more affected by movement; whether visual workload, expectation(More)
Persuasive technology is now mobile and context-aware. Intelligent analysis of accelerometer signals in smartphones and other specialized devices has recently been used to classify activity (<i>e.g.</i>, distinguishing walking from cycling) to encourage physical activity, sustainable transport, and other social goals. Unfortunately, results vary drastically(More)
Human sensitivity to vibration declines in mobile contexts. Designers of wearable haptic systems must account for the effects of movement and distraction so that tactile display information is perceived consistently. We compared the sensitivity of seven body sites in simulated mobile contexts, and found that the thigh is least and the wrists the most(More)
Computer interfaces often make large demands on users' attention, both to request and gather input and to provide output (feedback). In this position paper, we propose a new style of interaction that minimizes these attentional requirements while still providing support for rich input and output. Physiological data is used to drive the execution of a(More)
