The application enables the wearer to trace the data graphically, viewing the movements made in video form, extracting images and even printing them for later use. This can certainly come in handy for those ballerinas seeking to improve their choreography and hone their skills.


This piece of megaAVR based wearable technology is certainly a modern touch to a rather traditional art form, dating back to 16th century.
