<P>PROBLEM TO BE SOLVED: To provide an input method of a security code by a touch screen (5) of an electronic device such as a watch (1) for accessing a specific function, device or a prescribed place. <P>SOLUTION: The touch screen is provided with a control key which can be started by a manual operation of a user by a finger or a stylus. The respective keys are connected with a microprocessor unit of the electronic device. The finger or the stylus is placed on a key of the touch screen expressing a first gauge mark as a code to be inputted, the finger or the stylus is transferred from the key of the first gauge mark to a key of a second gauge mark on specific trajectories (d1, d2), the finger or the stylus is remained to be placed on the second gauge mark for prescribed period, or a change of the trajectories of the finger in a key area of the second gauge mark to be inputted is detected, the finger is transferred from the key of the second gauge mark to a key of a third gauge mark on specific trajectories (d3, d4), an input code is confirmed and the finger or the stylus is detached from the touch screen for accessing the function, the device and the specific place. <P>COPYRIGHT: (C)2004,JPO |
