Abstract

A computer in which entry of data from an area provided on a display, touch screen or the like is accomplished by the provision of a "soft keyboard". Misentry of data is avoided by providing for the calculation of an offset as may be required by the entry habits of a user which target areas of a defined key cell spaced from the center of the cell.
