Function control method, and terminal device
When, from a standby screen of a terminal device, a user depresses a motion key (S 11 ) and performs a registered movement (S 13 ), a sensor unit observes the movement of the terminal device, and a movement parameter calculation unit calculates a movement parameter. A movement parameter change decision unit decides (S 15 and S 16 ) whether or not a change of the movement parameter which is calculated, and a change of the movement parameter corresponding to a predetermined function registered in advance, agrees with one another. If the result of this decision is affirmative, a function control unit starts the corresponding function (S 17 ). As a result, it is possible to set the terminal device to a state in which the predetermined function can be employed, with a simple and easily remembered actuation.
1. A function control method for controlling the function of a terminal device, comprising:
a movement parameter calculation process of calculating the value of a movement parameter of said terminal device, based upon a value detected by a sensor which detects a state of movement of said terminal device, wherein values of accelerations in the X direction and the Y direction, and values of magnetic fields in the X, Y and Z directions are detected by the sensor and a roll angle, a pitch angle, an X direction acceleration and a Y direction acceleration are calculated using the values detected;
a movement parameter decision process of deciding whether or not the value of the movement parameter calculated by said movement parameter calculation process corresponds to an allocated motion shortcut, wherein Dynamic Programming Matching is carried out to determine if the value of the movement parameter corresponds to the allocated motion shortcut; and
a function setting process of, if an affirmative decision is reached in said movement parameter decision process, setting a predetermined function which corresponds to said allocated motion shortcut to a state in which it can be utilized.
2. A function control method as described in claim 1 , characterized in that said movement parameter is parameters including an acceleration and an attitude angle of said terminal device.
3. A function control method as described in claim 1 , characterized in that said motion shortcut is determined by combining at least one movement with another movement which are determined in advance.
4. A function control method as described in claim 1 , characterized in that said predetermined function is a function which can be set to a state in which it can be used, by command input from an operation unit of said terminal device.
5. A function control method as described in claim 4 , characterized in that a command input for releasing security is included in the command input from said operation unit.
6. A terminal device, comprising:
a sensor unit which acquires information necessary for calculating the value of a movement parameter;
a movement parameter calculation unit which calculates a value of the movement parameter from the value detected by said sensor unit;
a movement parameter decision unit which decides whether or not the value of said movement parameter which has been calculated corresponds to an allocate d motion shortcut; and
a function control unit which, if an affirmative decision is reached by said movement parameter decision unit, sets a predetermined function which corresponds to said allocated motion shortcut to a state in which it can be utilized, wherein
values of accelerations in the X direction and the Y direction, and values of magnetic fields in the X, Y and Z directions are detected by the sensor unit and a roll angle, a pitch angle, an X direction acceleration and a Y direction acceleration are calculated by the movement parameter calculation unit using the values detected; and
Dynamic Programming Matching is carried out to determine if the value of the movement parameter corresponds to said allocated motion shortcut.
7. A terminal device as described in claim 6 , characterized by further comprising an operation unit, and in that said predetermined function is set to a state in which it can be used, by command input from said operation unit.
8. A terminal device as described in claim 6 , characterized by further comprising a wireless communication unit for communicating with a base station of a mobile communication net.
