Robin’s ‘Bio-Rhythm Visualiser’ transforms personal health data into a dynamic visual guide designed to provide real-time motivational and instructive feedback when exercising. It utilises an Apple Watch's biometric monitor to stream heart rate, blood pressure, and body temperature data to a Raspberry Pi 3 B. This Pi drives a high-density WS2812B NeoPixel strip, which lights up accordingly.
The whole is mounted in a portable rectangular ‘exercise caddy’: which doubles as a secure phone stand, and measures 24cm x 9cm x 4cm.
The user inserts their phone, landscape-format, into the slot at the top front of the rectangular PLA plastic caddy. Beneath the slot is an inset just large enough to hug the phone, while providing a clear view of and access to the phone’s screen.
Set into the caddy beneath the phone is a horizontally-positioned LED light strip, that lights up in response to the data from the user’s Apple Watch. The wiring and Raspberry Pi 3 B is encased within the caddy out of sight.
As the exhibitor statement explains, “placed on the gym floor, the bright, evolving light patterns offer instant, visual feedback on physiological effort, optimising workout intensity and safety”.
