VHP: Vibrotactile Haptics Platform for On-body Applications
summary
VHP is an open hardware vibrotactile platform that drives 12 independent channels of arbitrary waveforms at a 2 kHz sampling rate, using an nRF52 MCU, PWM with second-order low-pass and D-class amplifiers, and on-board mics and accelerometer. Measured latency is ~4 ms, battery life ranges 3–25 hours, nine actuators run at full power from a battery (all 12 require a bench supply), and built bracelets and phone-case prototypes support audio-to-tactile lipreading use and reliable load sensing.
