ActiVibe: Design and Evaluation of Vibrations for Progress Monitoring
summary
A wristwatch prototype uses a single-actuator vibrotactile language to encode progress from 1–10 with short and long pulses inspired by Roman-numeral inspired grouping, delivered on a commercial smartwatch (Pebble) up to 12 times a day. Lab tests show >96% recognition, a 28-day in situ deployment with 22 participants and ~4,600 responses yields 88.7% overall accuracy, good stationary performance but poor recognition while running and sensitivity to social context and pre-signal design.
