The invention discloses a method and device for switching writing, selecting and erasing modes through gestures. The method comprises: detecting multi-finger touch information input by a user; judgingwhether one of a single-finger writing judgment condition, a two-finger selection judgment condition and a five-finger erasure judgment condition is met or not according to the multi-finger touch information, and if the single-finger writing judgment condition is met, entering a writing operation mode; if the two-finger selection judgment condition is met, entering a selection operation mode; entering an erase operation mode if the five-finger erase judgment condition is met; and if any one of the three judgment conditions is not met, repeatedly executing the step of detecting the multi-finger touch information input by the user. According to the invention, rapid switching of writing, selecting and erasing functions can be realized, function switching can be carried out without operatinga function button, the operation is convenient, the response is rapid, and the use is very convenient for a user.
