Gesture-Based Equipped Accessible Tour-de-France Bike

Members: Samuel Greene, Kenneth Page Swanson, Faizan Khan

The GREAT interface enhances the experience of riding a bike! The rider sees a real-time speedometer (using a Hall Effect sensor on the wheel) on a uLCD screen on the handlebars. The rider wears a glove (with an accelerometer and flex sensor) to control blinkers (LEDs) on the back of the bike: left, right, and brake. The GREAT bike can also store previous trip data in an SD card.

Instructions

Put the glove on your left hand. Power on the GREAT Bike interface in the enclosure in the basket. Start biking! The conventional hand signals for left and right correspond to the appropriate blinkers. Braking the bike turns on the brake light. Check your real-time speed, distance, and time travelled on the uLCD screen!
