VizEmo is a portmanteau of ‘Visual’ and ‘Emotion’. It comprises Lifelog Wristband, Beacon, and Interactive Display. It also uses wearable heart rate (HR) and electrodermal activity (EDA) sensors to the underside of the wristband that can be worn comfortably for long periods of time. The wristband can be personalized by the child wearer using fun and colored stickers and other materials. This prototype captures children’s physiological data through the wrist-mounted sensors, which are sent through a wireless network to beacons mounted throughout a classroom. Color-coded emotions (e.g. joy is yellow, sadness is blue, anger is red, disgust is green, and fear is purple) for individual children or all aggregated emotions of the children (e.g. joy of problem solving) are projected as an ambient light (e.g. yellow) or an art piece (e.g. sunshine painting) on the walls, floor, and ceiling of the classroom.
