Abstract

The invention relates to a transformation method of handwriting and erasure of a capacitive screen. Handwriting or erasure operation is determined through the detection of the contact area of a handwriting medium and the capacitive screen, when a handwriting medium with a small contact area is used for operating the capacitive screen, the input mode is transferred to a handwriting mode, and when the handwriting medium with a large contact area is used for operating the capacitance screen, the input mode is transferred to an erasure mode.

Description

The hand-written conversion method of wiping of a kind of capacitance plate
Technical field
The invention belongs to capacitance plate handwriting recognition field.
Background technology
Capacitive touch screen is used for mobile terminal, mobile phone, panel computer etc. more and more.Some software (as mapping software, handwriting record etc.) need to be changed between hand-written or erasing mode.Be all to increase a wipe icon on screen at present, realize the conversion of hand-written erasing mode by clicking wipe icon.This method is more loaded down with trivial details, and using to the user makes troubles.
Summary of the invention
Realize conversion between hand-written erasing mode in the present invention by the method that detects hand-written medium and capacitance plate contact area size.At first, the contact area of hand-written medium on capacitance plate is different, and the capacity effect of generation is also different.The hand-written medium that varies in size with contact area operates on capacitance plate and just can judge hand-written or wipe.As can the thick end of an end thin in capacitance pen, a thin end be used for handwriting input, and a thick end is used for wiping when erasing rubber, also can come handwriting input with thin capacitance pen, works as erasing rubber with finger and realizes erase operation.Do not need to realize the hand-written conversion of wiping by clickable icon, use more convenient.Above-described capacitance pen refers to the pen-like object that all can be used for inputting on capacitance plate.

Claims (3)

1. hand-written conversion method of wiping of capacitance plate, it is characterized in that deciding hand-written or erase operation by the size that detects hand-written medium and capacitance plate surface of contact, when hand-written medium and capacitance plate contact area hour are write operation, be erase operation when contact area is larger.
2. hand-written medium according to claim 1, the variation of its contact area size can realize that by the large small end of capacitance pen namely capacitance pen one end is thin, an end is thick, represents hand-writtenly with a thin end in contact capacitance plate, represents to wipe with a thick end in contact capacitance plate.
3. hand-written medium according to claim 1, the variation of its contact area size can realize by the medium with different thicknesses, represents hand-writtenly with thin capacitance pen hand capacity screen, represents to wipe with the finger contact capacitance plate.
