First Claim
1. Data input apparatus for recognizing any of a plurality of characters inputted by an operator, comprising:
- a character input region for inputting a single character;
said character input region including a plurality of sensors for sensing operator inputs and generating sensor signals indicative thereof and a plurality of predefined tile areas for sensing operator input of respective portions of the single character, each tile area including at least one of said plurality of sensors;
movable input means for providing operator inputs to any of said plurality of sensors by inputting data relevant to said tile areas;
analyzing means receiving said sensor signals for recognizing a character being inputted by the operator;
said analyzing means comprising;
first means responsive to said sensor signals for detecting an operator input to a first tile area representing a first portion of the character where said movable input means is first sensed by a sensor and generating a first tile identification signal indicative thereof;
second means responsive to said sensor signals for detecting an operator input to a second tile area representing a second portion of the character where said movable input means is secondly sensed by a sensor and generating a second tile identification signal indicative thereof; and
third means responsive to said first tile identification signal and said second tile identification signal representing said first and second portions of the character for recognizing a character being inputted by the operator and generating a character signal indicative thereof.

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.
