    Abstract: A see-through dimming panel includes first and second transparent substrate layers and suspended-particle-device (SPD) layer therebetween. A first transparent conductor layer is between the first transparent substrate layer and the SPD layer, and a second transparent conductor layer is between the second transparent substrate layer and the SPD layer. A first electrode is electrically coupled to the first transparent conductor layer. Second and third electrodes are electrically coupled to opposite ends of the second transparent conductor layer. An electric potential difference applied between the first and second electrodes controls a transmittance level of the SPD layer. An electric potential difference applied between the second and third electrodes, which results in a transverse electric field, controls a speed at which the transmittance level of the SPD layer decreases when the electric potential difference applied between the first and second electrodes controls is decreased.

    Abstract: Methods for tracking the head position of an end user of a head-mounted display device (HMD) relative to the HMD are described. In some embodiments, the HMD may determine an initial head tracking vector associated with an initial head position of the end user relative to the HMD, determine one or more head tracking vectors corresponding with one or more subsequent head positions of the end user relative to the HMD, track head movements of the end user over time based on the initial head tracking vector and the one or more head tracking vectors, and adjust positions of virtual objects displayed to the end user based on the head movements. In some embodiments, the resolution and/or number of virtual objects generated and displayed to the end user may be modified based on a degree of head movement of the end user relative to the HMD.

    Abstract: 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.

A first electrode is electrically coupled to the first transparent conductor layer. Second and third electrodes are electrically coupled to opposite ends of the second transparent conductor layer. An electric potential difference applied between the first and second electrodes controls a transmittance level of the SPD layer. An electric potential difference applied between the second and third electrodes, which results in a transverse electric field, controls a speed at which the transmittance level of the SPD layer decreases when the electric potential difference applied between the first and second electrodes controls is decreased.
