  • Publication number: 20100159908
    Abstract: A system for reconfiguring a mobile device based on environmental input is disclosed. The mobile device uses various components, including camera, microphone, and accelerometer, to gather data about the local environment. The system uses these components, separately or together, to determine the level of activity of the local environment. If the system determines that there is little activity in the local environment for a specified period of time, it enters low presence mode. In low presence mode, the system reconfigures the mobile device. The reconfiguration may include pausing or stopping applications, changing the device's volume settings, redirecting incoming telephone calls or text messages, or deactivating individual hardware components.

  • Publication number: 20100159981
    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.
