Abstract: The present technology relates to artificial reality systems. Such systems provide projections a user can create to specify object interactions. For example, when a user wishes to interact with an object outside her immediate reach, she can use a projection to select, move, or otherwise interact with the distant object. The present technology also includes object selection techniques for identifying and disambiguating between objects, allowing a user to select objects both near and distant from the user. Yet further aspects of the present technology include techniques for interpreting various bimanual (two-handed) gestures for interacting with objects. The present technology further includes a model for differentiating between global and local modes for, e.g., providing different input modalities or interpretations of user gestures.

Abstract: A self-detection mechanism for an IC is disclosed that determines whether the IC's internal bus is in a hanging state. An initialization sequence can be modified after a soft reset by reading data from an internal DRAM of the IC using a Direct Memory Access (DMA) controller as part of the initialization sequence. The read command is issued over the internal bus and, if the bus is hanging, the read command is not completed. Monitoring can be performed by waiting a predetermined period of time (e.g., 100ms) to determine if the read was properly completed. If so, no further action is needed. If the read was not completed, then a hard reset is requested to be performed. Thus, an initialization sequence can be modified to run dummy transactions through the internal bus, and validate that all paths are functional.

Abstract: A method for processing a stream of input images is described. A stream of input images that are from an image sensor is received. The stream comprises an initial sequence of input images including a subject having an initial orientation. A change in an angular orientation of the image sensor while receiving the stream of input images is determined. In response to determining the change in the angular orientation, a subsequent sequence of input images of the stream of input images is processed for rotation to counteract the change in the angular orientation of the image sensor and maintain the subject in the initial orientation. The stream of input images is transmitted to one or more display devices.
