Abstract

The invention relates to the field of electronic technology, and discloses a touch control method of a terminal and a terminal. The terminal includes a fingerprint recognition key, and the terminal can be controlled to complete a predefined task according to the distance and direction of a user's finger moving on the fingerprint recognition key. The touch method of the terminal includes: periodically receiving the fingerprint information of the user's finger on the fingerprint identification key, and collecting the fingerprint features in the fingerprint information each time the fingerprint information of the user's finger is received; According to the location information of the fingerprint feature, calculate the displacement of the fingerprint feature within the preset time, the preset time is longer than the receiving cycle of the fingerprint information; according to the size and direction of the fingerprint feature displacement indication, the control terminal completes Pre-defined tasks. The touch method of the terminal and the terminal are used to use fingerprint recognition keys to complete predefined tasks, such as moving a cursor or picture in various directions, scrolling, turning pages, turning on and off a machine, and the like.
