Abstract
Abstract A computer based touchscreen includes a mechanism for displaying buttons on the touchscreen indicating the location where an user has touched the touchscreen. Because different operators will view the buttons from different angles, they will touch the touchscreen in different positions. An initial button or series of buttons of the application that the user is using is configured to sense the location where the user is touching. These initial button(s) are called adjusting buttons. The button sensing regions for the remaining buttons (non-adjusting buttons) are calibrated from these initial touched locations. For example, if the user tends to press high and to the right of the adjusting button(s), the orientation of the button sensing regions for the remaining buttons is calibrated high and to the right. Any screen that displays buttons can be used to calibrate or recalibrate the button sensing region for subsequent non-adjusting buttons. This allows for greater accuracy should the users change their view or angle of the touchscreen as they use the application. Thus, the computer dynamically adjusts the orientation of a touchscreen button's sensing region based on the location that the user has pressed for previous buttons. This dynamic adjustment allows a high density of buttons to be displayed on the touchscreen.
