Embodiment Construction

[0034] figure 1 A schematic diagram illustrating a conventional optical motion sensor 101 is provided. The optical motion sensor includes an illuminating light source 102 , such as a light emitting diode (LED) 102 , and a light detector 103 coupled to a motion processor 104 . The optical movement sensor 101 is arranged to track movement of the surface 105 relative to the optical movement sensor 101 . This is done by the light detector 103 capturing image data corresponding to the area 106 illuminated by the light source 102 below the optical movement sensor 101 . As will be understood, although not in figure 1 As shown in , a typical optical sensor also includes optical elements to direct light from the light source 102 onto the imaged area 106 and to focus light reflected from the imaged area 106 onto the light detector 103 . Motion processor 106 receives image data captured from light detector 104 and continuously generates a series of images of area 106 . These images a...

Abstract

The invention discloses a system, a device and a method of gesture recognition. The system comprises a user input device including a plurality of optical sensors. Each of the optical sensors is arranged to detect a velocity of one of one or more user parts relative to said optical sensor. The user input device is arranged to generate movement data corresponding to the detected velocity of the one or more user parts. The system further comprises a gesture processor arranged to receive the movement data, match the movement data with one or more pre-defined gestures and generate corresponding control information associated with the one or more predefined gestures, wherein movement data corresponds to motion vectors representing a velocity of the one or more user parts relative to the optical sensors.

Description

technical field [0001] The present invention relates to systems, devices and methods for gesture recognition, and in particular for receiving gesture input from a user. Background technique [0002] The use of pointing devices such as mice, trackballs, and touchpads, etc., to allow a user to control the position of a cursor or the like on a display screen has been known for many years. More recently, however, more gesture-based control techniques have been developed that attempt to go beyond simple cursor control by enabling the device to recognize specific "gestures" entered by the user. Gestures of this class have control actions associated with them. For example, a "pinch" gesture can be used to zoom out, a "spread out" gesture can be used to zoom in, and a "swipe" gesture can be used to scroll, among other things. [0003] Gesture-based controls are used to allow users to interact with computing devices such as smartphones, tablet computers, portable personal computers...
