Abstract: A head-mounted device may have a head-mounted support structure, a gaze tracker in the head-mounted support structure, and one or more displays in the head-mounted support structure. For example, two displays may display images to two eye boxes. The display may display a virtual keyboard and may display a text input in response to a gaze location that is determined by the gaze tracker. The gaze tracker may additionally determine a gaze swipe input, or a camera in the support structure may determine a hand swipe input, and the swipe input may be used with the gaze location to determine the text input. In particular, the swipe input may create a swipe input curve that is fit to the text input to determine the text input. A user's hand may be used as a secondary input to indicate the start or end of a text input.

Abstract: The present disclosure generally relates to methods and user interfaces for positioning a virtual keyboard in a three-dimensional environment, displaying various types of virtual keyboards, for switching between virtual keyboards, and/or displaying a virtual keyboard based on a position of a user.

Abstract: Embodiments of the present disclosure provide an optical medium, for enabling increase in the viewing field angle without increasing a thickness of a device. The optical medium includes: a substrate having an upper interface and a lower interface parallel to each other; a first anisotropic partially-reflective film and a second anisotropic partially-reflective film being parallel to each other and arranged between the upper interface and the lower interface of the substrate in an inclined way; and a total reflection film arranged within the substrate in a direction of inclination opposite to that of the first and second anisotropic partially-reflective films. Embodiments of the present disclosure further provide glasses including the optical medium and an imaging method for the glasses.
