Third Eye
Blind spot detection system for cyclists in congested urban streets.
Goal:
to minimize accidents as a resultof rider - vehicle collisions, creating a safer riding environment andencourage cycling as an accessible form of transportation.
Solution:
Third Eye consists of twocomponents, and ultrasonic sensor and an LED display. The ultrasonic sensorsits in a housing attached to the bike’s seat post facing behind the rider. Awire from the sensor runs along the top tube of the frame with the brake cablesto the stem when the LED display is located. The Housing for the display simplyreplaces on of the spacers on the stem of the bike and extends over thehandlebars, angled to be comfortably viewed by the rider.
The closer an object gets to the sensor, the brighterand more sporadically the lights will flash. Giving the rider and indication ofthe distance of the object behind them in their blind spot. All without havingto take their eyes off of the road to check behind them.
