    Abstract: An access control application for mobile devices is provided. The access control application may be configured to generate a set of security tasks based at least in part on information corresponding to a user's interactions with the mobile device. An unlock screen of the mobile device may be triggered and a security tasks from the generated set of security tasks may be displayed through a user interface of the mobile device. The user's response to the security tasks may be obtained and a confidence score may be calculated, based at least in part on the response. The access control application may then determine, based at least in part on the score and one or more attributes of the environment, whether to unlock the mobile device or prompt the user to provide an additional response to another security task.

    Abstract: Approaches to enable a computing device, such as a phone or tablet computer, to compute a probability that the user currently using the device matches a profile of an authorized user and to set or change a security level of the computing device based on the computed probability. The security level can be one of many security levels each having a different scope of authorized access to data or functions of the computing device. The computing device may periodically re-compute the probability and change the security level whenever the probability crosses certain predefined thresholds.

    Abstract: A system and method determines whether a finger touch on a touch screen device is outside the defined boundary of a touch target. In such situations a device may adjust the location coordinates of the finger touch to adaptively correspond to an appropriate touch target based on such factors as context, region, distance from touch target, user history, device movement, parallax, etc. The method and system may also be applied to overlapping touch targets.

    Abstract: Content is presented by media devices to a user. Described herein are techniques and systems for determining occurrence of one or more events at, or proximate to, the media device. Once an event is determined, one or more actions to modify presentation of the content may be initiated. The actions may include starting presentation of the content, stopping presentation of the content, applying noise mitigation techniques to the content, and so forth. The noise mitigation techniques may include modification of an intended signal from the content to produce a noise mitigation zone 118 proximate to, or encompassing, at least a portion of the user's head.

    Abstract: Techniques for determining positions of devices within an environment are described herein. In some instances, an environment, such as a home or office of a user, may include an array of devices, some or all of which may couple to a network or to other devices via short-range wireless connections (e.g., Bluetooth®, Zigbee®, etc.). These devices may capture an array of data for providing to a central service, which is configured to analyze the data and, based on this analysis, determine a location of the devices relative to one another. That is, the central service may analyze the data to determine relative distances and orientations between the identified devices within the environment.
