Abstract

A command recognition method and electronic device using the method are described. The command recognition method includes obtaining at least two first contact points at side edge of the electronic device; determining a holding gesture with respect to the electronic device according to the at least two first contact points; obtaining at least one second contact point at which contact state is changed on a side edge of the electronic device in a predetermined time period; based on the holding gesture, the at least one second contact point and its corresponding contact state change, recognizing corresponding command. By use of the command recognition method, it can favorably achieve the recognition of the operation command with respect to the electronic device in the case that the number of keys in the electronic device (even no key) is reduced, thereby achieving effective control to the electronic device.
