Patent ID: 10758824

Abstract:
A virtual reality system comprising a headset, a primary battery, a secondary battery (provides backup power), an output device which displays a 3-D virtual world (VW) based on the orientation and position of the headset. Swapping of the primary battery with a physical battery is viewed in the (VW) using virtual counterparts of the primary battery and the secondary battery in an output device in the headset. A user physically swaps the batteries while “seeing” the swapping taking place in the VW. The locations the user sees (through the headset) the primary battery and secondary battery correspond to their locations in the real world relative to the headset so that while the user physically feels (with his/her hands) the primary battery and the secondary battery the locations of the primary battery and the secondary battery in the VW correspond to what the user feels so that the swapping feels “real.”
