Mobile device and method for proximity detection verification
First Claim
1. A method for proximity detection verification, the method comprising:
- enabling a touch screen display and a touch screen circuit on a mobile device;
activating a proximity sensor with a commencement of a telephone call;
receiving from the proximity sensor an indication that a user is in close proximity to the display;
acquiring one or more images of a scene in front of the touch screen display;
analyzing the one or more images to determine if the user is in a position to view the display; and
disabling at least one of the display or the touch screen circuit if the proximity sensor provides the indication that the user is in close proximity to the display and a processor of the mobile device determines based upon the analyzing that the user is not in a position to view the display.

Abstract
A mobile device includes a touch screen display and touch screen circuit for receiving touch inputs. A camera configured to acquire one or more images in front of the display. A proximity sensor configured to provide an indication that a user is in close proximity to the touch screen display. A processor being effective to determine, in response to the indication of the proximity sensor, whether the user is in a position to view the display based on the one or more images of the camera. If the proximity sensor provides an indication that the user is in close proximity to the display and the processor determines, based on the one or more images, that the user is in a position to view the display, then at least one of the display and the touch screen circuit are not disabled.

14. A method for proximity detection verification, the method comprising:
-
enabling a touch screen display and a touch screen circuit on a mobile device; activating a proximity sensor with a commencement of a telephone call; receiving from the proximity sensor an indication that a user is in close proximity to the display; acquiring one or more images of a scene in front of the touch screen display; focusing a camera lens on the user positioned in front of the display; analyzing the one or more images and the position of the lens with reference to a threshold position to determine if the user is in close proximity to the display; and disabling at least one of the display or the touch screen circuit if the proximity sensor provides the indication that the user is in close proximity to the display and a processor of the mobile device determines based upon the analyzing that the user is not in a position to view the display. - View Dependent Claims (15, 16, 17)
