Cyclists share the road with other vehicles, often leading to problems when drivers fail to see or respect the rider’s space. To try and alleviate these issues, [Matlek] built the Smartglove to help cyclists communicate their intentions to other road users.
The project consists of a glove fitted with an Arduino Nano 33 BLE sense, featuring Bluetooth and motion sensing on board. Combined with TinyML machine learning code, the Arduino is able to sense hand gestures from the rider. These gestures are then interpreted, and relevant messages displayed on an LED screen worn on the rider’s back. Flicking the wrist left and right flashes indicators that the user is about to change direction, while a rearward flick flashes a warning that the user is braking.
It’s a tidy way to integrate vehicle-style lighting into a simple interface for cycling. This has benefits, particularly at night, for allowing other road users to see a cyclist and understand their intentions on the road. Of course, if you really want to be noticed, this bike boombox could also be a big help. Video after the break.
