Title:
DEVICE AND METHOD FOR DETECTING MOVEMENT USING PROXIMITY SENSOR
Document Type and Number:
WIPO Patent Application WO/2012/030078
Kind Code:
A3
Abstract:
A device for detecting movement for detecting the movement of an object on a touch area comprises: three or more proximity sensors, which are two-dimensionally and separately arranged on the touch area, each of the proximity sensors for measuring electric scalars which correspond to the distance to the object on the touch area; and a control unit for calculating the vector of a second touch position, which is modified in relation to a first touch position, using a first electric scalar and a second electric scalar that are measured with a predetermined time difference therebetween, thereby calculating the movement of the object in terms of the vector to generate a movement signal.
