It uses the standard wii-mote functionality, with the wii-mote glued over the back of the hand and wrist. Ironically this gives it far better sensing capability than the original Power Glove as the original could only detect roll; this detects pitch and yaw as well. For additional functionality, the modder wired the A and B buttons into the fingertips of the index and ring fingers respectively. Curl them forwards to activate.
