Abstract: Disclosed is a system, apparatus, computer readable storage medium, and method to perform a transition triggered context monitoring for a mobile device. A first sensor data stream comprising data from one or more sensors at the mobile device is received. One or more features calculated from the data of the first sensor data stream may be monitored and a status change for the one or more features is detected. In response to detecting the status change, of a second sensor data stream comprising data from one or more sensors at the mobile device is collected. The second sensor data stream may be processed as a context label for a segment of the first sensor data stream and the segment beginning may be defined by the status change.

Abstract: System and methods are disclosed to use information available on the state of mobile devices in a heuristics-based approach to improve motion state detection. In one or more embodiments, information on the WiFi connectivity of mobile de vices may be used to improve the detection of the in-transit state. The WiFi connectivity information may be used with sensor signal such as accelerometer signals in a motion classifier to reduce the false positives of the in-transit state. In one or more embodiments, information that a mobile device is connected to a WiFi access point (AP) may be used as heuristics to reduce the probability of falsely classifying the mobile device in the in-transit state when mobile device is actually in the hand of a relatively stationary user. Information on the battery charging state or (he wireless connectivity of the mobile devices may also be used to improve the detection of in-transit state.

Abstract: Sensor data from a sensor system of a mobile device may be used for determining a level of pressure exerted by a user on the mobile device. The sensor system may include one or more types of sensors, such as a microphone and one or more inertial sensors. The inertial sensors may include one or more gyroscopes and/or accelerometers. Based on the inertial sensor data, it may be determined whether and/or how the mobile device is being held. A process for determining a level of pressure exerted by a user on the mobile device may be adapted based, at least in part, on whether and/or how the mobile device is being held. The pressure determining process may be adapted according to various other criteria, such as a position of a touch target in a display, ambient noise levels, etc.
