Description

technical field

[0001] The invention relates to handwriting input and gesture recognition technology, in particular to a method and device for handwriting input and gesture recognition of mobile equipment. Background technique

[0002] Mobile devices, such as mobile phones, mainly have three technical methods for Chinese input in the domestic market, namely pinyin input, stroke input and handwriting input. The survey conducted on the scope of use shows that the proportion of pinyin input tops the list at 79.7%, and the proportion of stroke input and handwriting input is 15.7% and 4.6% respectively. However, with the growth of SMS business, the problem of "thumb fatigue" caused by pinyin input and stroke input is gradually exposed. At this time, the handwriting input technology is becoming more and more mature, making it the most favored by users after the miniaturization of mobile devices. Input. A number of survey results show that nearly 80% of the respondents regard mob...
