<P>PROBLEM TO BE SOLVED: To correct a positional deviation of an actual touched position from a desired pressing position due to a gap between a touch panel and a display part. <P>SOLUTION: A touch position detector detects variations in loads detected by load sensors S1-S4, specifically X-direction components and Y-direction components of the variations in the loads, calculates an angle γ and an angle θ on the basis of the components, and detects coordinates (Xt,Yt) of a regular position from the angle γ, the angle θ, and XY coordinates (X0,Y0) of a touched position. Calculating the angle γ and the angle θ, which are values corresponding to a user position with respect to a touch panel display, can detect the user position. Then, correcting a positional deviation of the touched position on the basis of the user position indicated by the angle γ and the angle θ and a gap d can accurately detect the regular position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
