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.
