Abstract
A device and method of identifying the position of a determinant via combining optical image with a single axis of touch panel includes sensing identification of any single axis via only one image sensor module provided at a side or outside the work area for retrieving images and combining with the identification device of the touch panel in the work area, then, calculating the relative position of the determinant through the triangulating relationship and the formula x×tan θ=y in response to retrieved images and identified information from the touch panel.

A device for identifying the position of a determinant via combining an optical image with a single axis of touch panel, comprising:
- an image sensor module provided at the side of or outside a work area for retrieving images in said work area;
- a first touch panel provided in said work area, which is a low level touch panel with a single axis which a determinant locates;
- and
- a calculating unit with at least one ray from a transmitter of said image sensor module, a fiducial line, and said axis for intersecting to form a triangle, for sensing the identification of any said single axis via said image sensor module for retrieving images and combining with the identification device of said first touch panel, for then, calculating the relative position of said determinant in said work area through the triangulating relationship and the formula x×tan θ=y combining with the retrieved images and identified information from said first touch panel.
A method of identifying the position of determinant via combination with an optical image and a single axis of touch panel, including:
- retrieving images in said work area by an image sensor module provided at the side of or outside a work area;
- detecting an axis which a determinant locates by a first touch panel provided in said work area, wherein said first touch panel is a low level touch panel with a single axis for;
- sensing an identification of any said single axis via only one said image sensor module and combining with said identification from said first touch panel by a calculating unit, such that at least one ray from a transmitter of said image sensor module, a fiducial line, and said axis intersect to form a triangle;
- and
- calculating a relative position of said determinant in said work area and the location of said determinant through triangulation and the formula x×tan θ=y in response to retrieved images information and identified information from said first touch panel.
