    Abstract: Technologies for determining a user's location by a mobile computing device include detecting, based on sensed inertial characteristics of the mobile computing device, that a user of the mobile computing device has taken a physical step in a direction. The mobile computing device determines a directional heading of the mobile computing device in the direction and a variation of an orientation of the mobile computing device relative to a previous orientation of the mobile computing device at a previous physical step of the user based on the sensed inertial characteristics. The mobile computing device further applies a Kalman filter to determine a heading of the user based on the determined directional heading of the mobile computing device and the variation of the orientation and determines an estimated location of the user based on the user's determined heading, an estimated step length of the user, and a previous location of the user at the previous physical step.

    Abstract: A user device including a haptic feedback system configured to receive and process data captured by one or more sensors and determine contextual characteristics of the user device and a surrounding environment based on the captured data. The contextual characteristics may include, but are not limited to, ambient noise level and ambient light level of the surrounding environment, as well as user possession, movement and/or use and interaction with the device. The haptic feedback system is further configured to adjust haptic feedback effects of the user device based, at least in part, on the contextual characteristics of the user device and surrounding environment so as to provide an optimized haptic feedback effect to the user.

    Abstract: An efficient approach for estimating scalefactors for use in the quantization of audio signal spectrum values is described. The scalefactor estimation approach can be implemented in multiple stages. A first stage estimates a distortion level for a selected scalefactor band spectrum value based on a received maximum tolerant distortion threshold and the spectrum values in the scalefactor band. A second stage determines an interim process value based on the previously estimated distortion level and generates a scalefactor for a selected scalefactor band spectrum value based on the generated interim process value and a statistically predetermined fraction. A third stage generates a scalefactor that applies to the whole scalefactor band based on the scalefactor generated for the selected scalefactor band spectrum value. The approach provides a performance gain of 40% over previous techniques, thereby reducing device power requirements and audio encoder bottlenecks.

    Abstract: System and methods are provided for dynamic performance adjustment of a media playing pipeline. For example, the media playing pipeline includes one or more components synchronized for media playing. A reference component in the media playing pipeline is selected, the reference component having a component performance level. A pipeline performance level of the media playing pipeline is determined. When the pipeline performance level is higher than a threshold, the component performance level of the reference component is adjusted to decrease the pipeline performance level. When the pipeline performance level is lower than the threshold, the component performance level of the reference component is adjusted to increase the pipeline performance level.
