ANTI-TRIP WHEN IMMERSED IN A VIRTUAL REALITY ENVIRONMENT
First Claim
1. A method performed by a head mounted display (HMD) device supporting rendering of a virtual reality environment, comprising:
- obtaining sensor data describing a physical space adjoining a user of the HMD device;
using the sensor data, reconstructing geometries of real world objects located in the physical space;
determining a distance between the user and the real world objects using the reconstructed geometries; and
if the distance is equal to or less than a predetermined threshold, then operating the HMD device so that the user can see the real world objects without obstruction from the virtual reality environment.

Abstract
An HMD device with a see-through display and depth sensing capability is configured to selectively dim or fade out a display of a virtual reality environment to enable a user to see the real world without obstruction by the virtual world when a distance between the user and a real world object is determined to be less than a threshold distance. The current height of the user'"'"'s head (i.e., the distance from head to ground) may be utilized when performing the dimming/fading so that different threshold distances can be used depending on whether the user is standing or seated.

11. A head mounted display (HMD) device operable by a user in a physical environment, comprising:
-
one or more processors; a see-through display employing additive blending between real world and virtual world display elements; and one or more memory devices storing computer-readable instructions which, when executed by the one or more processors, perform a method comprising the steps of; generating surface reconstruction data using a depth sensor or camera system, using the surface reconstruction data, determining a distance to a real world object in the physical environment from a volumetric shape that represents the user, and operating the HMD device so that at least a portion of the see-through display is seen through by the user when the real world object is within a threshold distance from the volumetric shape. - View Dependent Claims (12, 13, 14, 15, 16)

17. One or more computer readable memories storing computer-executable instructions for implementing a method for providing an anti-trip feature for an immersive virtual environment rendered for a user of a head mounted display (HMD) device in a physical environment, the method comprising the steps of:
-
configuring display optics incorporated into the HMD device for selectively transparent operation by dimming the rendering of the virtual environment; dynamically modeling the physical environment and real world objects contained therein using surface reconstruction; determining a distance from the user to a real world object in the surface reconstructed model; and dimming the display optics for transparent operation to enable the user to see the real world object through the display optics when the distance is equal to or less than a predetermined threshold. - View Dependent Claims (18, 19, 20)
