Abstract

The operation input device includes: an operation determination unit configured to determine which one of the floating touch operation and the touch operation is input; a calculation unit configured to calculate an input position of the operation on the operation panel; a display information generation unit configured to generate display information for displaying a pointer at a position on a display screen corresponding to an input position calculated by the calculation unit when the operation determination unit determines that the floating touch operation is input; and a display device output unit configured to output the display information generated by the display information generation unit to a display device having the display screen displaying the pointer.

Claims

1. An operation input device including an operation panel configured to receive an input of a floating touch operation and a touch operation, comprising:

an operation determination unit configured to determine which one of the floating touch operation and the touch operation is input;

a calculation unit configured to calculate an input position of the operation on the operation panel;

a display information generation unit configured to generate display information for displaying a pointer at a position on a display screen corresponding to an input position calculated by the calculation unit when the operation determination unit determines that the floating touch operation is input; and

a display device output unit configured to output the display information generated by the display information generation unit to a display device having the display screen displaying the pointer.

2. The operation input device according to claim 1, further comprising:

a touch operation information generation unit configured to generate touch operation information based on the touch operation, if the operation determination unit determines that the touch operation is input, and

a control device output unit configured to output the touch operation information generated by the touch operation information generation unit to a control device which is controlled by the touch operation or the floating touch operation.

3. The operation input device according to claim 2, further comprising:

a floating touch operation information generation unit configured to generate floating touch operation information based on the floating touch operation, if the operation determination unit determines that the floating touch operation is input,

wherein the control device output unit outputs the floating touch operation information generated by the floating touch operation information generation unit to the control device.

4. The operation input device according to claim 1, further comprising:

a transformation unit configured to transform the input position calculated by the calculation unit into a display position on the display screen, based on a resolution on the display screen of the display device and a resolving power of the input position of the operation panel.

5. The operation input device according to claim 2, further comprising:

a transformation unit configured to transform the input position calculated by the calculation unit into a display position on the display screen, based on a resolution on the display screen of the display device and a resolving power of the input position of the operation panel.

6. The operation input device according to claim 3, further comprising:

a transformation unit configured to transform the input position calculated by the calculation unit into a display position on the display screen, based on a resolution on the display screen of the display device and a resolving power of the input position of the operation panel.

7. An input operation processing method using an operation input device including an operation panel configured to receive an input of a floating touch operation and a touch operation, comprising steps of:

determining which one of a floating touch operation and a touch operation is input;

calculating an input position of the operation on the operation panel;

if it is determined that the floating touch operation is input, generating display information for displaying a pointer at a position on a display screen corresponding to the calculated input position; and

outputting the generated display information to a display device having the display screen displaying the pointer.
