Abstract: A wireless controller for a video game playing device includes electrically conductive contacts on portions of the surface of the controller positioned so that a first contact is contactable by one hand of the user and a second contact is contactable by the other hand of the user during operation of the controller. Electrical circuitry applies a voltage between the first contact and the second contact so that when the one hand contacts the first contact and the other hand contacts the second contact an electrical current flows through the user's body completing an electrical circuit. Further electrical circuitry enables power supply to the controller electronic control circuitry responsive to completion of the electrical circuit, and disables electrical power supply to the controller electronic control circuitry responsive to breaking of the electrical circuit.
