Abstract
A method of calculating a coordinate of a touch medium is disclosed in the present invention. The method includes obtaining a first image to determine whether the first image overlaps a first threshold, generating a first interceptive boundary when the first image overlaps the first threshold, obtaining a second image to generate a second interceptive boundary by overlap of the second image and a second threshold, determining whether the first interceptive boundary overlaps the second interceptive boundary, and confirming a status of the touch medium according to determination.
