Abstract: In one embodiment, a method includes detecting a touch event on a side-mounted touchpad of a computing device during display of a current user interface of an application executing on the computing device. The application includes a navigation hierarchy with a home user-interface layer, multiple sub user-interface layers, and multiple user-interface branches. The method includes determining a particular sub user-interface layer and user-interface branch that the current user interface corresponds to and determining a type of the touch event. When the type of the touch event is a forward touch event and there is a next sub user-interface layer in the particular user-interface branch of the current user interface, the method navigates to the next user-interface layer in the particular user-interface branch of the current user interface.

Abstract: In one embodiment, a user of a mobile device navigates between application user interface layers by using touch inputs to the mobile device's side-mounted touchpad.

Abstract: Client devices periodically capture ambient audio waveforms, generate waveform fingerprints, and upload the fingerprints to a server for analysis. The server compares the waveforms to a database of stored waveform fingerprints, and upon finding a match, pushes content or other information to the client device. The fingerprints in the database may be uploaded by other users, and compared to the received client waveform fingerprint based on common location or other social factors. Thus a client's location may be enhanced if the location of users whose fingerprints match the client's is known. In particular embodiments, the server may instruct clients whose fingerprints partially match to capture waveform data at a particular time and duration for further analysis and increased match confidence.

Abstract: In particular embodiments, a temporary user is able to use another's personal computing device in shared mode for a short period of time while experiencing a personalized user interface. An indication is detected that a personal computing device associated with a primary user is to be shared with a temporary user. Access to local personal information associated with the primary user is disabled if it is stored on the personal computing device. Access to remote personal information of the primary user that is accessible from the personal computing device is disabled. A personalized user interface incorporating personal information associated with the temporary user is presented on the personal computing device for the temporary user. Personal information of the primary user is not accessible by the temporary user, and vice versa. When shared mode is to be terminated, all personal information of the temporary user is deleted.
