摘要： A mechanism is described for facilitating adjustment of video encoding rates and adaption of views in computing environments according to one embodiment. An apparatus of embodiments, as described herein, includes logic to track data associated with movement of a computing device accessible to a user, and logic to evaluate the data and compare a latency with latency thresholds, where the data indicates the latency and the latency thresholds associated with a frame. The apparatus further includes logic to maintain a current video encoding rate, if the latency is lower than a first latency threshold and greater than a second latency threshold. The current video encoding rate is decreased if the latency is equal to or greater than the first latency threshold, where the current video encoding rate is increased if the latency is lower than the second latency threshold. The apparatus further includes logic to present the frame at the computing device including one or more of a wearable device and a mobile device.

摘要： Techniques are provided for spatial audio streaming using adaptive bitrate encoding and decoding in bandwidth limited virtual reality applications. A methodology implementing the techniques according to an embodiment includes calculating weight factors for audio channels associated with each of a plurality of microphones. The weight factors are based on the position and head angle, relative to the microphones, of a user wearing a head mounted display (HMD). The method also includes encoding and decoding the audio channels, for transmission to the HMD, at a selected bitrate, the bitrate based on the weight factor for the audio channel. The method further includes applying an adaptive gain compensation to each of the received and decoded audio channels, the gain compensation also based on the weight factor. The method further includes mixing the resulting gain compensated channels to generate a stereo audio signal to be played through speakers of the HMD.

摘要： A method for determining orientation of an electronic device relative to another electronic device is described. The method includes synchronizing internal clock of a first electronic device with internal clock of a second electronic device using electromagnetic signals communicated between the first electronic device and the second electronic device, sending two or more sound waves from the second electronic device, receiving the two or more sound waves at the first electronic device, and calculating orientation of the first electronic device relative to the second electronic device based on a difference in time of arrival of the two or more sound waves at the first electronic device. The first electronic device and the second electronic device each have at least one transceiver configured to send and receive electromagnetic signals. The first electronic device has two or more acoustoelectric transducers and the second electronic device has one or more acoustoelectric transducer.
