Title: TOUCH DETECTION METHOD AND DEVICE
Abstract:
The present invention provides a touch detection method and a device. The touch detection method comprises: obtaining coordinates of associated points of touch points; obtaining distance values between the touch points in the direction of a measurement axis; obtaining to-be-determined coordinates of the touch points based on the coordinates of the associated points and the distance values between the touch points in the direction of the measurement axis; determining actual coordinates of the touch points according to the to-be-determined coordinates. The touch detection device comprises: a unit for determining associated points, applicable to obtain coordinates of associated points of touch points; a unit for determining a distance, applicable to obtain distance values between the touch points in the direction of a measurement axis; a unit for determining to-be-determined coordinates, applicable to determine to-be-determined coordinates of the touch points based on the coordinates of the associated points and the distance values between the touch points in the direction of the measurement axis; a unit for determining actual coordinates, applicable to determine actual coordinates of the touch points according to the to-be-determined coordinates.
