Abstract: Functionality is described herein for recognizing speakers in an energy-efficient manner. The functionality employs a heterogeneous architecture that comprises at least a first processing unit and a second processing unit. The first processing unit handles a first set of audio processing tasks (associated with the detection of speech) while the second processing unit handles a second set of audio processing tasks (associated with the identification of speakers), where the first set of tasks consumes less power than the second set of tasks. The functionality also provides unobtrusive techniques for collecting audio segments for training purposes. The functionality also encompasses new applications which may be invoked in response to the recognition of speakers.

Abstract: Various embodiments facilitate linking physical documents to digital documents. Links link physical documents to digital documents. Using a sensor, the physical documents are automatically detected and identified on a digital workspace. A computer is capable of displaying graphics, and user interaction with displayed graphics can be detected. The digital workspace displays a GUI component having one or more controls, and the GUI component is displayed at a location relative to a physical document on the digital workspace. User interaction with the control is detected and either a link between the physical document and one of the digital documents is edited, or an existing link between the physical document and a digital document is used to perform an operation on the digital document. Alternatively or additionally, links may be automatically generated digital documents determined to be implicitly related to the physical document.

Abstract: Methods and systems for using a foot-based interface to interact with a computer are described. An application program from a plurality of application programs is executed on an operating system of a personal computer. The application program is configured to receive user input via a foot-based interface. Further, user input is received from the foot-based interface and mapped into a command. Moreover, the command controls an application program function. Also, the command is executed and an output corresponding to the execution of the command is generated. Additionally, the output is displayed to the user.
