TOUCH-SCREEN DEVICE AND DYNAMIC ADJUSTING METHOD OF SENSING REGION

摘要

PURPOSE: To make it possible to accurately select a button by dynamically adjusting the orientation of the sense area for parallax elimination of a high- density touch screen. CONSTITUTION: One or a series of initial button for application business that users 24 and 26 use are so constituted as to sense positions that the users touch. Those initial buttons are called adjustment buttons. The button sense areas of the remaining buttons (non-adjustment button) are calibrated with those initial contact positions. For example, when the users 24 and 26 tend to press the right-upper parts of the adjustment buttons, the orientation of the button sense areas of the remaining buttons are calibrated to the right upper parts. When plural adjustment buttons are used, the mean of touched positions is used to calibrate the button sense areas of the non-adjustment buttons. The adjustment buttons are not limited to only the start of the application business. The subsequent button sense areas of the non-adjustment buttons can be calibrated or recalibrated whichever screen for displaying buttons 20a is used.
