Information processor input button display that prevents selection of undesired button

摘要

An information processor includes a means for displaying a plurality of item buttons in a display region, the item buttons each having center coordinates and outlines, a means for determining coordinates of an indicated position in the display area based on an input signal, a means for calibrating the center coordinates of each of the plurality of item buttons to coordinates between the center coordinates and the outlines of each of the item buttons to obtain the calibrated center coordinates, and a means for determining one of the item buttons to be in a selected state such that the calibrated center coordinates of the determined one is closest to the coordinates of the indicated position.

1. An information processor, comprising:
a means for displaying a plurality of item buttons in a display region, the item buttons each having center coordinates and outlines; a means for determining coordinates of an indicated position in the display area based on an input signal; means for calibrating the center coordinates of each of the plurality of item buttons to coordinates between the center coordinates and the outlines of each of the item buttons to obtain the calibrated center coordinates based on the outlines; and a means for determining, each and every time an item button is selected, which of the item buttons is in a selected state by determining which of the calibrated center coordinates of the item buttons is closest to the coordinates of the indicated position, wherein the calibrating means operates such that the center coordinates are displaced in a direction toward one of the outlines by a predetermined percentage of a width of each of the item buttons to obtain the calibrated center coordinates.
