Abstract: Various embodiments enable a user to provide an input to an application by covering or otherwise obscuring one or more cameras of a computing device in a predetermined sequence. For example, as content is displayed by a computing device, image information is captured with multiple cameras. Upon detecting a portion of a hand of a user, such as a finger, passing over two or more of the cameras, a sequence in which the hand passes over the cameras is compared to sequences stored by the computing device. In this example, each sequence stored by the computing device corresponds to an input to an application to launch the application, cause a function to be executed using the application, and the like. Accordingly, in response to the sequence matching one of the stored sequences, an input is provided to an application corresponding to the sequence.

Abstract: Initiating a functionality of an electronic device using the device cover and/or other device inputs is described herein. In some implementations, a sequence of operations may be stored on the device to initiate a specific functionality of the device. Each operation in the sequence may correspond to a manipulation of a position of a device cover or an input from a device input component. Once the device determines that two or more received operations complete the stored sequence, the specific functionality of the device may be initiated.
