  • Publication number: 20160253053
    Abstract: Electronic equipment is controlled with a touching-type signal input device. An inputted navigator-calling request that specifies a user request to navigate among a set of previously-opened application views of different applications is received. A request mode of the inputted navigator-calling request is compared with a predefined request mode associated with navigation among the set of previously-opened application views of the different applications. It is determined whether the request mode of the inputted navigator-calling request matches with the predefined request mode. An open-views navigator is displayed in response to determining there is a match. The open-views navigator has a set of open-views tabs distributed on at least part of a closed structure that each allow selective navigation to a previously-opened application view of one of the different applications.

  • Patent number: 9417699
    Abstract: A method and system for using an image sensor to control applications on a mobile device is disclosed. The system uses image processing to detect control gestures by the user. Control gestures may include, for example, moving a hand laterally, moving the hand closer or farther away from the camera, or opening and closing a hand. These control motions are linked to user commands to be executed by the application being controlled. The system initializes by storing a background image showing the field of view of the image sensor before any objects are present. It then detects new objects in the field of view by comparing new images to the background image. If a new object is detected, the system waits until the object is stationary in the field of view. After the object is stationary, the system detects if there is a change in the object indicating a control gesture.
