Abstract
Techniques are described for device locking with activity preservation at a specified level within a multi-level hierarchy of device states. Such locking enables a user to share a device with another user while specifying a particular level of access to the device, such as access to a particular class of applications, a specific application, or a specific task within an application. Determination of the authorized activity may be based on a currently active application, or on the particular user gesture. The level of functionality made available may be based on the number of times a user gesture is repeated. Gestures may include a selection of a hardware or software control on the device, issuance of a voice command, and the like.
