摘　　要：随着智能手机等电子产品的普及,多点触摸屏应用越来越广泛。但是因触摸屏表面较光滑,使得盲人不能通过触觉获得屏幕的信息,造成其输入文字困难。提出采用多点触摸联机手写识别盲文技术的汉字输入法。该方法不仅解决了盲人能利用多点触摸屏输入文字信息,也能应用于明眼人的触摸屏联机手写盲文识别进行汉字输入,其书写汉字速度远高于现有的触摸屏的手写输入法。With the popularity of smart phones and other electronic products,the application of multi-touch screen has been increasingly widespread.However,since the smooth surface of the touch screen,the blinds cannot get the information through touching the screen,and it results in the difficulty for the blinds to input words on touch screen as well.The paper presents the Chinese input method by using online handwritten braille recognition technology with multi-touch gestures.This work not only enables the blinds to input text information through multi-point touch screen,but can also be applied to the sighted person in Chinese input with touch screen online handwritten braille recognition,and the speed of Chinese writing is much higher than existing handwriting input method for touch screen.
