Patent ID: 8108000

Claim:
An electronic device, comprising: at least one temperature sensor comprising a plurality of temperature sensing units for detecting a touch operation on a surface of the temperature sensor from an object, and detecting information of the touch operation, wherein the detected information of the touch operation comprises time spent by the touch operation on passing through adjacent temperature sensing units; a storage system for storing predetermined information, wherein the predetermined information comprises predetermined standards for determining if any touch operation on the surface of the temperature sensor is a valid touch operation, and a command corresponding to the valid touch operation, the predetermined standards comprising a predetermined time range of the time spent by the valid touch operation on passing through adjacent temperature sensing units; and at least one processor that analyzes the detected information from the temperature sensor, compares the detected information with the predetermined standards to determine if the touch operation is a valid touch operation, and executes the command to activate a corresponding action of the electronic device, in response to a determination that the touch operation is a valid touch operation, wherein the predetermined standards further comprise a predetermined sliding direction of a valid touch operation on the surface of the temperature sensor, and a predetermined temperature range of the valid touch operation.
