Title: (EN) Unlocking a head mounted device
Abstract: front page image
(EN)

Embodiments described herein may help to provide a lock-screen for a computing device. An example method involves, while a computing device is in a locked mode, the computing device: (a) analyzing head-pose data to determine whether a head pose associated with the computing device matches a predetermined head pose, (b) analyzing touchpad data associated with the computing device to detect a predetermined sequence of touch gestures, (c) if both (i) the head pose matches the predetermined head pose and (ii) the predetermined sequence of touch gestures is detected, then the computing device switching to an unlocked mode, and (d) otherwise, refraining from causing computing device switch to the unlocked mode.
