METHOD FOR INPUTTING ALPHABET BASED ON TRACKING TOUCH SHAPE

摘要

PURPOSE: A method for inputting alphabets by tracking a touch is provided to place reference alphabets on a center and arrange alphabets of similar shapes to the reference alphabets around the reference alphabets, thereby enabling a user to easily input English characters by a simple touch input. CONSTITUTION: A display area is divided into four areas. Reference alphabets are allocated to the areas. The alphabets are allocated to the four areas around the reference alphabets(S802). Alphabets allocated to the areas are displayed on a screen(S804). If a push event is generated in the reference alphabets, a coordinate where the push event is generated is compared with a coordinate where a release event is generated(S808). One of alphabets displayed on the screen is selected based on a moving direction(S810).
