Abstract
A head mounted display (HMD) adjusts feature tracking parameters based on a power mode of the HMD. Examples of feature tracking parameters that can be adjusted include the number of features identified from captured images, the scale of features identified from captured images, the number of images employed for feature tracking, and the like. By adjusting its feature tracking parameters based on its power mode, the HMD can initiate the feature tracking process in low-power modes and thereby shorted the time for high-fidelity feature tracking when a user initiates a VR or AR experience at the HMD.
