    Abstract: Various embodiments are provided herein for tracking a user's physical environment, to facilitate on-the-fly blending of a virtual environment with detected aspects of the physical environment. Embodiments can be employed to facilitate virtual roaming by compositing virtual representations of detected physical objects into virtual environments. A computing device coupled to a HMD can select portions of a depth map generated based on the user's physical environment, to generate virtual objects that correspond to the selected portions. The computing device can composite the generated virtual objects into an existing virtual environment, such that the user can traverse the virtual environment while remaining aware of their physical environment. Among other things, the computing device can employ various blending techniques for compositing, and further provide image pass-through techniques for selective viewing of the physical environment while remaining fully-immersed in virtual reality.

    Abstract: Representative embodiments disclose mechanisms for selection of items using eye tracking. One or more primary selection targets are presented to the user. When the user selects a primary selection target, secondary selection targets are presented in close proximity to the primary selection target, either before or after selection of the primary selection target. The secondary selection targets are animated in a way that moves them away from the primary selection target. The user's eye naturally follows the secondary selection target of interest, if any, producing a vector having a magnitude and a direction. The magnitude and direction of the vector are used to identify which, if any, of the secondary selection targets are intended ty the user.

    Abstract: A unique system and method is provided that facilitates pixel-accurate targeting with respect to multi-touch sensitive displays when selecting or viewing content with a cursor. In particular, the system and method can track dual inputs from a primary finger and a secondary finger, for example. The primary finger can control movement of the cursor while the secondary finger can adjust a control-display ratio of the screen. As a result, cursor steering and selection of an assistance mode can be performed at about the same time or concurrently. In addition, the system and method can stabilize a cursor position at a top middle point of a user's finger in order to mitigate clicking errors when making a selection.

    Abstract: Dynamic haptic retargeting can be implemented using world warping techniques and body warping techniques. World warping is applied to improve an alignment between a virtual object and a physical object, while body warping is applied to redirect a user's motion to increase a likelihood that a physical hand will reach the physical object at the same time a virtual representation of the hand reaches the virtual object. Threshold values and/or a combination of world warping a body warping can be used to mitigate negative impacts that may be caused by using either technique excessively or independently.
