Abstract
A multi-character continuous handwriting input method where a character is written on a touch unit and after an ith character is written, an (i+1)th character is written in an overlapping manner on the ith character. When a user is writing, it is determined whether a current stroke belongs to the ith character or (i+1)th character; if it is the (i+1)th character, the display color of the ith character is dimmed automatically, so that the user clearly sees the newly written character on a display screen. Multiple characters can be written continuously without pauses and when an (i+2)th character is written, the ith character disappears automatically from the screen, and the color of the (i+1)th character is dimmed automatically. Thus, the ability to continuously write multiple handwritten characters on a screen and the corresponding recognition and display processing significantly improves the input efficiency of handwritten text.
