A head mounted display (HMD) device is configured with a sensor package that enables head tracking to determine the device user's proximity to virtual objects in a mixed reality or virtual reality environment. A fade volume including concentrically-arranged volumetric shells is placed around the user including a near shell that is closest to the user, and a far shell that is farthest from the user. When a virtual object is beyond the far shell, the HMD device renders the object with full opacity (i.e., with no transparency). As the user moves towards a virtual object and it intersects the far shell, its opacity begins to fade out with increasing transparency to reveal the background behind it. The transparency of the virtual object increases as the object gets closer to the near shell and the object becomes fully transparent when the near shell reaches it so that the background becomes fully visible.

Smart transparency for virtual objects

An HMD device renders a virtual reality environment in which areas of the real world are masked out so that real world objects such as computer monitors, doors, people, faces, and the like appear visible to the device user and no holographic or virtual reality content is rendered over the visible objects. The HMD device includes a sensor package to support application of surface reconstruction techniques to dynamically detect edges and surfaces of the real world objects and keep objects visible on the display as the user changes position or head pose or when the real world objects move or their positions are changed. The HMD device can expose controls to enable the user to select which real world objects are visible in the virtual reality environment.

Virtual reality environment with real world objects

Methods for managing content within an interactive augmented reality environment are described. An augmented reality environment may be provided to an end user of a head-mounted display device (HMD) in which content (e.g., webpages) may be displayed to the end user using one or more curved slates that are positioned on a virtual cylinder that appears body-locked to the end user. The virtual cylinder may be located around the end user with the end user positioned in the middle of the virtual cylinder such that the one or more curved slates appear to be displayed at the same distance from the end user. The position and size of each of the one or more curved slates may be controlled by the end user using head gestures and a virtual pointer projected onto the virtual cylinder.
