Augmented reality based driver assistance

Abstract

A head mounted display (HMD) device worn by a user in a vehicular computing environment (VCE) can be augmented with video by measuring, within the VCE, a sight angle between a user's directional focus and a vehicle's directional orientation and augmenting, in response to a determination that the measured sight angle exceeds a threshold limit, an interface of the HMD device with a video feed of continuous live content captured within a central viewing area.
