TOUCH DETECTION METHOD AND DEVICE
First Claim
1. A touch detection method, comprising:
- obtaining coordinates of a point associated with touch points;
obtaining distances between the touch points in a direction of an axis to be measured;
determining indeterminate coordinates of the touch points based on the coordinates of the point associated with the touch points and the distances between the touch points in the direction of the axis to be measured; and
determining actual coordinates of the touch points according to the indeterminate coordinates of the touch points.

Abstract
A touch detection method and device are provided. The method includes: obtaining coordinates of a point associated with touch points; obtaining distances between the touch points in a direction of an axis to be measured; determining indeterminate coordinates of the touch points based on the coordinates of the point associated with the touch points and the distances between the touch points in the direction of the axis to be measured; and determining actual coordinates of the touch points according to the indeterminate coordinates of the touch points. The device includes: an associated point determining unit, adapted for obtaining coordinates of a point associated with touch points; a distance determining unit, adapted for obtaining distances between the touch points in a direction of an axis to be measured; an indeterminate coordinate determining unit, adapted for determining indeterminate coordinates of the touch points based on the coordinates of the point associated with the touch points and the distances between the touch points in the direction of the axis to be measured; and an actual coordinate determining unit, adapted for determining actual coordinates of the touch points according to the indeterminate coordinates of the touch points.
