METHOD FOR ERGONOMIC RECOGNITION IN TOUCH SCREEN KEYBOARD

摘要

A method for recognizing an ergonomic touch screen key of the present invention is configured to detect a user ellipse, in which an ellipse parameter is detected, in a user button key press pattern, convert the user ellipse into a key recognition area (i), and calculate an overlapping width between the user ellipse and a similar user button key, so the key recognition area (i) is determined to be a learning key recognition area, in which learning is carried out, with a user input button key or the key recognition area (i) is determined to be an area, in which learning is not carried out, with the user input button key. As the ellipse parameter is changed from the learning key recognition to central point learning, a database (DB) of specific location key press shapes is constructed by key. Specifically, as user intention key reasoning for an user input across a plurality of keys is performed along with recognition area control for each key using a value of the constructed DB, the possibility of recognizing typographical errors is reduced, and a future touch habit of the user is reflected by learning a user′s input pattern.
