Abstract: Disclosed are systems, methods and devices for improving audio processing and playing multiple sounds using fewer resources. Various implementations may create audio files, in some cases from a single sample of a type of sound, where the files represent specific quantities of that type of sound, such as 10 footsteps or 1000 claps. Given a desired target number of sounds to play, various implementations determine an appropriate combination of the employable audio files to represent the desired number of sounds, and play or render the combination as an approximation of the desired target number of sounds. By using single audio files that represent and sound like multiple instances of a specified type of sound, the various implementations use significantly fewer computing and audio resources than playing an equivalent number of audio files each of which contains a single instance of the specified type of sound.

Abstract: An access control technology is described. Ownership control information is stored for an object in a computing system. Access control to objects in the computing system is based in part on accounts having ownership control of objects in the computing system. A first account with ownership control of the object is identified. Ownership control of the object is changed to a second account upon detection of a first security event. Ownership control of the object is restored to the first account upon detection of a second security event using the stored ownership control information.

Abstract: Various embodiments enable additional content or features to be displayed to a user in response to detecting one eye of the user being closed either as a wink or for a duration of time. In one example, the additional content is graphical overlay, such as a menu containing selectable graphical elements to perform functions related to an application, game, or content, of global navigational features of the computing device in general, or to alternate views, features, or supplemental content for an application or game currently being displayed on a computing device. In one example, the overlay may be displayed only as long as the user keeps one eye closed or, alternatively, the user could wink to display the overlay and provide some other input to remove the overlay.

Abstract: A computing device can track a gaze direction of a user of the computing device. In some embodiments, gaze tracking can be performed using at least one front-facing camera of the computing device. The computing device can determine a position on a display of the device that corresponds to where the user's gaze is directed. The computing device can display content that is decipherable (i.e., readable, legible, recognizable, understandable, non-scrambled, unobscured, etc.) at the position on the display that corresponds to the user's gaze direction. The computing device can scramble at least some content that is displayed at a position(s) on the display other than the position at which the user's gaze is directed.

Abstract: Approaches are described for generating an audio signal that mimics speech captured a computing device. An input audio signal (e.g., a speech signal) can be transformed from the time domain into another domain, to generate one or more audio signal segments, where each segment can correspond to a window of time. The device can then determine, for each audio signal segment, a feature characteristic of the audio signal, such as a phoneme. Each one of segments can be mapped, based at least in part on the respective feature characteristic, to a model audio signal. The device can then generate an output audio signal including each model audio signal as determined by the mapping, where the output audio signal is in a sequence associated with the input audio signal.
