    摘要: Methods for recognizing gestures within a near-field environment are described. In some embodiments, a mobile device, such as a head-mounted display device (HMD), may capture a first image of an environment while illuminating the environment using an IR light source with a first range (e.g., due to the exponential decay of light intensity) and capture a second image of the environment without illumination. The mobile device may generate a difference image based on the first image and the second image in order to eliminate background noise due to other sources of IR light within the environment (e.g., due to sunlight or artificial light sources). In some cases, object and gesture recognition techniques may be applied to the difference image in order to detect the performance of hand and/or finger gestures by an end user of the mobile device within a near-field environment of the mobile device.

    摘要: The techniques and mechanisms described herein are directed at property management mechanisms that operate within an on-demand property system. The property management mechanisms support the caching of property values on an as needed basis, allow a plurality of object instances to utilize the same property via attached properties, overriding default information associated with a property on a per type basis, obtaining values for a property from an external source, and the like. In addition, the on-demand property system provides validation and control for each property instance. The property management mechanisms minimize the storage requirements and provide flexibility without requiring additional code from the developers.
