IdeaBall - Hardware


Communication between the IdeaBall and IdeaBallNavigator is accomplished by a bluetooth connection. Turn taking is recognized by recording a change in the RFID tag read. The IdeaBall provides audio feedback to signal the change in RFID tags read, and consequently that the ball changed hands. Interaction between users and the IdeaBall is achieved by shaking the ball.
