Abstract: A head mounted display (HMD) device operating in a real world physical environment is configured with a sensor package that enables determination of an intersection of a device user's projected gaze with a location in a virtual reality environment so that virtual objects can be placed into the environment with high precision. Surface reconstruction of the physical environment can be applied using data from the sensor package to determine the user's view position in the virtual world. A gaze ray originating from the view position is projected outward and a cursor or similar indicator is rendered on the HMD display at the ray's closest intersection with the virtual world such as a virtual object, floor/ground, etc. In response to user input, such as a gesture, voice interaction, or control manipulation, a virtual object is placed at the point of intersection between the projected gaze ray and the virtual reality environment.

Abstract: An HMD device is configured to vertically adjust the ground plane of a rendered virtual reality environment that has varying elevations to match the flat real world floor so that the device user can move around to navigate and explore the environment and always be properly located on the virtual ground and not be above it or underneath it. Rather than continuously adjust the virtual reality ground plane, which can introduce cognitive dissonance discomfort to the user, when the user is not engaged in some form of locomotion (e.g., walking), the HMD device establishes a threshold radius around the user within which virtual ground plane adjustment is not performed. The user can make movements within the threshold radius without the HMD device shifting the virtual terrain. When the user moves past the threshold radius, the device will perform an adjustment as needed to match the ground plane of the virtual reality environment to the real world floor.

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.

Abstract: Embodiments are disclosed that relate to operating a user interface on an augmented reality computing device comprising a see-through display system. For example, one disclosed embodiment includes identifying one or more objects located outside a field of view of a user, and for each object of the one or more objects, providing to the user an indication of positional information associated with the object.

Abstract: Embodiments that relate to presenting a plurality of visual information density levels for a plurality of geo-located data items in a mixed reality environment are disclosed. For example, in one disclosed embodiment a graduated information delivery program receives information for a first geo-located data item and provides a first visual information density level for the item to a head-mounted display device. When a spatial information density of geo-located data item information is below a threshold, the program provides a second visual information density level greater than the first level for a second geo-located data item displayed.

Abstract: Embodiments that relate to presenting a plurality of visual information density levels for a plurality of geo-located data items in a mixed reality environment are disclosed. For example, in one disclosed embodiment a graduated information delivery program receives information for a selected geo-located data item and provides a minimum visual information density level for the item to a head-mounted display device. The program receives via the head-mounted display device a user input corresponding to the selected geo-located data item. Based on the input, the program provides an increasing visual information density level for the selected item to the head-mounted display device for display within the mixed reality environment.

Abstract: A head mounted display (HMD) device operating in a real world physical environment is configured with a sensor package that enables determination of an intersection of a projection of the device user's gaze with a location in a mixed or virtual reality environment. When a projected gaze ray is visibly rendered on other HMD devices (where all the devices are operatively coupled), users of those devices can see what the user is looking at in the environment. In multi-user settings, each HMD device user can see each other's projected gaze rays which can facilitate collaboration in a commonly-shared and experienced mixed or virtual reality environment. The gaze projection can be used much like a finger to point at an object, or to indicate a location on a surface with precision and accuracy.
