ABSTRACT:
A data entry apparatus includes a mosaic display as a template for inputting characters, by a stylus or other device. The displayed mosaic includes a plurality of segments, each represented by a tile area of the template. Inputted characters are recognized based on first and second tile areas contacted by the stylus or otherwise selected by an operator. The two tile areas may be the same or different, and may be the initial and final areas of the input operation. To enable character input by no more than two operations, hinge tile areas are provided, each representing selection of a plurality of standard tile areas. The system further recognizes input characters in response to a single input stroke, based on the initial and final tile areas thereof and, when the stroke is imprecisely inputted, by reference to directional characteristics thereof.
