Abstract: An apparatus, system, and method are described that permit the sharing of a temporary software license from a first computing device to a second computing device. A geographic distance limitation condition may be imposed as a condition for the sharing, such as a proximity range. More generally, the geographical distance limitation may be based around a local area network limitation. One application is to use the geographical distance limitation to permit temporary sharing of a temporary key for a multi-player game in which the players are within a pre-selected geographical distance limitation, such as a distance limitation corresponding to the players being in the same room, within a pre-selected maximum distance, or in the short range local area network.

Abstract: A head mounted display (HMD) system is disclosed for presentation of visual images in which a post render processing unit (PRU) is built into the HMD to offload operations usually performed by the graphics processing unit (GPU) in the computer that is rendering the computer graphical images (CGI). The PRU takes advantage of local access to tracking and other sensors to reduce the latency traditionally associated with augmented and virtual reality operation.
