Abstract:

Techniques for predicting a virtual camera view in an augmented reality (AR) or virtual reality (VR) application. A first change in position of a user device over a first time period is determined based on analyzing a plurality of frames of image data related to an AR or VR application. A dead reckoning calculation is used to predict a second change in position of the user device over a second time period, based on the first change in position and data received from an Inertial Measurement Unit (IMU) associated with the user device. A plurality of frames of image data are generated for display in the AR or VR application, based on the predicted second change in position of the user device.

Abstract:

Techniques for aligning a virtual object with a physical object in an Augmented Reality (AR) or Virtual Reality (VR) application are described. An electronic peripheral includes a first inertial measurement unit (“IMU”). A head mounted display includes a second IMU. An estimated attitude for the electronic peripheral is generated using data from the first IMU. An estimated attitude for the head mounted display is generated using data from the second IMU. An orientation of a virtual object is determined based on the estimated first and second attitudes, such that the virtual object is aligned with an object in a user's physical environment when the virtual object is displayed to the user. The virtual object is displayed on the head mounted display.
