First Claim
1. A method comprising:
- detecting position data from a device comprising a light source, a screen, and at least one photodetector mounted on a face of the device, and an aperture defining a field of view of the at least one photodetector, wherein the screen and the aperture are flush with the face of the device, the field of view of the at least one photodetector is fixed and is tilted toward the screen of the device, and the position data is detected based on a non-contacting gesture performed in the field of view of the at least one photodetector; and
detecting, based on processing the position data, at least one of a signature gesture, a thumb gesture, or a hand gesture.

Abstract
In an example, a system for detecting an object in an area over a screen of a mobile device may comprise a light source and a photodetector tilted toward the screen. Since a field of view of the photodetector and a radiation field of the light source may be directed toward the screen, the system may detect that a user performed a non-contacting gesture in the area over the screen. In another example, a system for detecting multiple modes of finger gestures may detect at least one of a signature gesture, a thumb joystick mode, or a thumb mouse mode. The system can execute a calendar application upon detecting that a user gestured in the shape of a letter “C”. When detecting a thumb gesture, the system may utilize a sensor having a reduced range relative to the range needed for hand gestures and, thereby, reduce power consumption.

10. A gesture detection apparatus comprising:
-
a light source, a screen, and at least one photodetector mounted on a face of the gesture detection apparatus, the light source having a radiation field in which light is emitted;
the at least one photodetector having a field of view in which light is detected;an aperture defining the field of view, wherein the screen and the aperture are flush with the face of the gesture detection apparatus, and the aperture aligns the field of view in a direction that is fixed and is tilted toward the screen of the gesture detection apparatus; and at least one processor configured to perform operations comprising; detecting position data based on a non-contacting gesture performed in the field of view of the at least one photodetector; and detecting, based on processing the position data, at least one of a signature gesture, a thumb gesture, or a hand gesture. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
