Projects Galvactivator
The galvactivator is a glove-like wearable device that senses the wearer's skin conductivity and maps its values to a bright LED display. Increases in skin conductivity across the palm tend to be good indicators of physiological arousal, causing the galvactivator display to glow brightly. The galvactivator has many potentially useful purposes, ranging from self-feedback for stress management, to facilitation of conversation between two people, to new ways of visualizing mass excitement levels in performance situations or visualizing aspects of arousal and attention in learning situations. One of the findings in mass-communication settings was that people tended to "glow" when a new speaker came onstage, and during live demos, laughter, and live audience interaction. They tended to "go dim" during powerpoint presentations. In smaller educational settings, students have commented on how they tend to glow when they are more engaged with learning.
