Bike Speed Projector

Matt Richardson has created an interactive headlight projector for bikes that can be used to create a kind of unobtrusive heads-up display for cyclists. It works by measuring the rider’s speed using some custom electronics and a Raspberry Pi and a portable pico projector to display some text on the ground in front of the cyclist. The experience (which is shown on the video below) is somewhat similar to Google Glass in that it brings some useful data in a person’s field of view in an unobtrusive manner. (via TechCrunch)
