Abstract

Smart glasses (also commonly called digital eyewear) are mainly an extension of prescription eyewear, providing a digital contextual display to the prescription correction for visual impairment. This concept is functionally very different from either AR or MR functionality. The typical smart glass FOV remains small (less than 15 deg diagonal) and is often offset from the line of sight. The lack of sensors (apart the IMU) allows for approximate 3DOF head tracking, and lack of binocular vision reduces the display to simple, overlaid 2D text and images. Typical 3DOF content is locked relative to the head, while 6DOF sensing allows the user to get further and closer to the content.
