In words of the creator of the project:
«Project Aura is a bicycle lighting system designed to address the issue of nighttime urban bike commuting. The system challenges the current paradigm of bike lighting. It was our intention to create a functional safety lighting system that riders want to use and want to be seen using. Designed and built by myself and classmate Jonathan Ota. Funding was provided by the Carnegie Mellon Undergraduate Research Office
Riding at night can be a daunting and dangerous task; many biking commuters are faced with the issue of being obscured when riding on the streets. Visibility at night is a vital component of biker safety, hence the need for reflectors and attachable lights. However, some of these devices are not always effective especially from the side.
We created a system that requires very little rider input and maintenance, while increasing the visual footprint of bikers from all directions especially from the side. We accomplished this by expanding the surface area of light emitted through the use of RGB LEDs inside the rims of the wheels that change from red when slowing down to white when at cruising speed.»

Hand gestures, and maybe the occasional reflective strip on the back of a jacket or bicycle seat? Not for long. This DIY turn signal bicycle jacket uses Lilypad arduino technology…
