Abstract
A hand-written character/graphic is recognized in a character recognition mode or a graphic recognition mode designated in accordance with stroke information supplied from a tablet input device which samples the hand-written character/graphic and converts it to the stroke information. The recognition mode is automatically designated by comparing a longer one of projection lengths on x-axis and y-axis of stroke coordinates with a predetermined threshold for a hand-written character input.
