    Abstract: A mechanism is described for facilitating interest-based enhancement in media quality according to one embodiment. A method of embodiments, as described herein, includes receiving eye tracking information from a wearable computing device, where the eye tracking information contains data relating to pupils of eyes of a user having access to the wearable computing device. The method may further include enhancing quality of at least contents of media, if a size of a pupil is determined to have been altered due to the user's interest in the contents, where the media having the enhanced contents is encoded and communicated back to the wearable computing device to be rendered at the wearable computing device.

    Abstract: Components, devices, systems, and methods for providing a movable haptic actuator for a user interacting with a simulated environment. The simulated environment may be virtual reality, augmented reality, or mixed reality. A fastener may be used to couple the haptic actuator to a wearable article worn by the user. The haptic actuator communicates with a controller to receive information to provide feedback to the user during operations of the simulated environment. The haptic actuator may be movable from a first position on the wearable article to a second position.

    Abstract: Technology for adjusting touch resolution for a capacitive touch sensor. A touch resolution of a capacitive touch sensor is set to a first resolution. A footprint of an object in contact with a surface of the capacitive touch sensor is determined. The capacitive touch sensor is adjusted to a second resolution to detect objects based on the footprint of the object, wherein the second resolution is different than the first resolution.

    Abstract: Techniques are disclosed for combining sub-sampled chroma samples across multiple frames to include all color information for a given scene. In accordance with some embodiments, each frame may be encoded such that it contains different color samples in a sub-sampled color format. A sliding window across the desired number of frames, which can be varied based on the level of sub-sampling, may select the frames with the sub-sampled color data to be used for combination to recreate the scene with all color information, in accordance with some embodiments. The disclosed techniques can be used, for example, in the transfer and rendering of streaming or stored compressed video content that includes text. To such ends, the disclosed techniques can be used in any one, or combination, of RGB-YUV conversion, video encoding, and video frame combination. More generally, the disclosed techniques can be utilized in video content creation, as well as consumption.

    Abstract: One or more system, apparatus, method, and computer readable media is described for improving the quality of static image frames having a relatively long residence time in a frame buffer on a sink device. Where a compressed data channel links a source and sink, the source may encode additional frame data to improve the quality of a static frame presented by a sink display. A display source may encode frame data at a nominal quality and transmit a packetized stream of the compressed frame data. In the absence of a timely frame buffer update, the display source encodes additional information to improve the image quality of the representation of the now static frame. A display sink device presents a first representation of the frame at the nominal image quality, and presents a second representation of the frame at the improved image quality upon subsequently receiving the frame quality improvement data.

    Abstract: Techniques are provided for tracking objects in an encoded video stream based on data directly extracted from the video stream, thus eliminating any need for the stream to be fully or partially decoded. Extracted motion vector and DC coefficient data can be used to provide a rough estimation of which macro-blocks are be associated with a background motion model and which macro-blocks correspond to a foreground object which is moving with respect to the background motion model. Macro-blocks which are associated with a moving foreground object can be grouped based on connectivity and a similarity measure derived from the extracted DC coefficient data. The grouped macro-blocks can be tracked from frame to frame to identify and eliminate groups having only negligible motion. The resulting validated macro-block groups will correspond to a rough object mask associated with a moving region in the analyzed frame.

    Abstract: One or more system, apparatus, method, and computer readable media is described for reducing the GOP length during a direct pass-through of an encoded video stream format that is supported by the decoder at the sink. In some embodiments, the encoded video stream is decoded on the source device and employed to generate and insert supplemental intra-predicted frames (I-frames) at shorter intervals allowing for faster recovery in the event of lost packets/frames when transmitted to a sink display. In some embodiments, Residual Artifact Suppressed (RAS) inter-predicted frames are further created and inserted in place of any frames that reference a frame converted to a supplemental I-frame. The encoded video stream passed through will consist of all the original frames except for the supplemental I-frames reducing the GOP, and RAS inter-predicted frames modified to prevent propagation of residual induced artifacts.
