Professor Ted Selker of MIT's Media Lab invented this versatile helmet of multi-functions.It can play music or audio books, with hook-ups for an iPod or tape cassette. It can record speech through built-in microphones and GPS, warning the wearer of a hazard on a given route. It can also detect important sounds like a fire siren to mute music when necessary. It has a Motorola cell phone with Bluetooth installed so a bicyclist can talk on the phone, hands-free, while commuting.
