With the development of the mobile communication network and the development of the terminal specification, the mobile communication terminal has become a necessity of modern people and has evolved into a total entertainment device beyond the conventional category of simple communication apparatus or information providing apparatus.
In addition to telephone functions, such terminals are becoming widespread with various hardware devices installed therein, and are diversifying without being limited to telephone functions. In particular, various types of sensors mounted on a terminal have been introduced and a number of services utilizing sensors have been introduced.
The sensors mounted on the terminal are acceleration, geomagnetism, gyro, proximity, illumination, etc. Recently, temperature, humidity and air pressure sensors are also mounted. Meanwhile, along with an acceleration sensor or a gyro sensor for sensing the operation of the user's terminal, proximity sensors and motion sensors that detect the user's movement even when there is no direct movement of the terminal are also mounted on the terminal.
Such user motion recognition using the proximity sensor or the light intensity sensor is simple in the recognition method, so that the error of the motion recognition is not large.
