Problems solved by technology

[0003] However, cameras tend to have a limited optical sensing area, or field of view, and, because of the way they operate, they have difficulty interpreting certain gestures, especially those involving movement toward or away from the camera
So the ability to interpret three-dimensional gestures is very limited

Embodiment Construction

[0039] Embodiments described herein include devices or terminals, especially communication terminals, that use supplemental sensors to provide information characterizing the environment surrounding the terminal. Specifically, the sensor provides information to identify gestures, where the information is processed to identify an object in the sensor's corresponding sensing region and the object's motion.

[0040] Depending on whether an object is detected by only one sensor or by two sensors, a corresponding command or set of commands is used to control user interface functions of the terminal, eg to control some aspects of the terminal's operating system or applications associated with the operating system. Information corresponding to objects detected by only one sensor is processed to execute a first command or first set of commands, whereas information corresponding to objects detected by two or more sensors is processed to execute a second command or Second command group. ...

Abstract

Apparatus comprises a processor; a user interface enabling user interaction with one or more software applications associated with the processor; first and second sensors configured to detect, and generate signals corresponding to, objects located within respective first and second sensing zones remote from the apparatus, wherein the sensors are configured such that their respective sensing zones overlap spatially to define a third, overlapping, zone in which both the first and second sensors are able to detect a common object; and a gesture recognition system for receiving signals from the sensors, the gesture recognition system being responsive to detecting an object inside the overlapping zone to control a first user interface function in accordance with signals received from both sensors.

Description

technical field [0001] The present invention relates generally to gesture recognition, and particularly but not exclusively to recognizing gestures detected by a first sensor and a second sensor of a device or terminal. Background technique [0002] It is known to use video data received by a camera of a communication terminal to enable a user to control applications associated with the terminal. The application stores a mapping between predetermined user gestures detected using the camera and one or more commands associated with the application. For example, a known photo browsing application allows controlling how photos are displayed on the user interface using waving gestures performed in front of the terminal's front camera, a right-to-left gesture generally causing the application to advance in the order of the photos. [0003] However, cameras tend to have a limited optical sensing area or field of view, and because of the way they operate, they have difficulty inter...
