Latest Patents

Bar-zeev's latest patents include advanced video compression methods and apparatus designed for mixed reality systems. One notable invention features a head-mounted display (HMD) and a base station. The system allows information collected by HMD sensors to be transmitted to the base via wired or wireless connections. A rendering engine on the base renders frames that include virtual content based on sensor information. An encoder compresses these frames according to a specific encoding protocol before sending them to the HMD. Instead of relying on previous frames to estimate motion vectors, the system inputs motion vectors from both the HMD and the rendering engine into the encoder for frame compression. This innovative approach allows for the embedding of motion vectors in the data stream, enabling the HMD to synthesize frames if they are not received.

Another significant patent focuses on gaze-based user interactions. In this process, a placement point for a selected object is initially designated based on the user's gaze position. Upon receiving user input, the placement point can be moved to a different position that is not based on
