I swear iPod Nano is a character in a Douglas Adams book.
Anyway, these bijoux items now come with accelerometers on board…cutesy, but I’m not sure how valuable the functionality actually is.
Today’s invention is the DancePod, a personal network of iPods worn on the limbs, body and head. These are aware of the music being listened to and can sense how coordinated and in-time to that music one’s body movements are. The system will monitor one’s dancing prowess/effort over time and make comments such as ‘are you really sure about Hip-Hop?’
The system could be used to assess dancers (or even divers) quantitatively in competitions.
