Abstract

An input apparatus of an information device is selectively locked by physically installing a selective lock key in the information device, executing an application program installed therein, and blocking, if the selective lock key is handled after the application program is executed, input through a system key of the information device while accepting input through an application button. With this method, for example, an unintended touch on a system key while using an information device can be prevented.

Claims

1. A method of selectively locking an input apparatus of an information device having a touch screen as an input-output means and having a power/lock key configured to perform a method of locking an input means, the method comprising the steps of:

physically installing a selective lock key in the information device having a touch screen, and executing an application program installed in the information device having a touch screen; and

when the selective lock key is handled after the application program is executed, blocking input through a system key of the information device having a touch screen and accepting input through an application button.

2. A method of selectively locking an input apparatus of an information device having a touch screen as an input-output means and having a power/lock key configured to perform a method of locking an input means, the method comprising the steps of:

executing an application program installed in the information device having a touch screen;

outputting a selective lock object, which is a kind of application button, on a corresponding application program screen; and

when touch on the selective lock object is sensed, blocking input through a system key of the information device having a touch screen and accepting input through the application button.

3. An information device comprising:

a touch screen as an input-output means;

a power/lock key configured to perform a method of locking an input means;

a selective lock key installed therein; and

an application program installed therein,

wherein when the selective lock key is handled after the application program is executed, input through a system key of the information device is blocked, and input through an application button in accepted.
