Abstract

An input control device and an image forming apparatus capable of proving an easy-to-use operating environment even for a user having difficulties operating such conventional devices and apparatuses due to his/her height, color vision deficiency, weak vision, use of a wheelchair, and the like is disclosed. In the input control device, based on the detected distance between an instruction item on the display and an operation direction means (such as a user'"'"'s finger), the display mode of the instruction item is changed (by, for example, changing positions, colors, and combinations). Further, as the operation direction means approaches, the size of the instruction item on the display becomes larger, thereby improving the operability especially for a user with color vision deficiency or weak vision.

Claims

1. An input control device for an electronic apparatus, the input control device comprising:

plural selection operation units each inputting the information of an instruction item selected from prescribed instruction items related to the corresponding operations of the electronic apparatus;

a selected information output unit outputting the information of the instruction item input through each of the selection operation units to the electronic apparatus; and

a display operation unit which is one of the selection operation units, the display operation unit including;

a display unit for displaying the instruction items,

an input unit for inputting the information of the instruction item selected from among the instruction items displayed on the display unit,

an instruction position detection unit for detecting the position of operation instruction means for selecting the instruction item displayed on the display operation unit, and

a display control unit for changing a display mode of the display unit in accordance with the distance between the operation instruction means and the instruction item that is detected by the instruction position detection unit and that is displayed on the display unit.

2. The input control device according to claim 1, wherein

when any of the selection operation units each removably mounted on the input control device is separated from the input control device, the display control unit changes the display mode of the instruction items of the selection operation units in accordance with which of the selection operation units is separated from the input control device.

3. The input control device according to claim 2, wherein

the display control unit divides the display of the display unit in accordance with which of the selection operation units is separated, and when the display control unit changes the display mode of the area for one of the selection operation units, the display control unit does not change the display mode of the areas of the other selection operation units.

4. The input control device according to claim 1, wherein

the display control unit is capable of selecting the display modes including the determination whether the display control unit changes the display mode in accordance with which of the selection operation units is separated from the input control device.

5. The input control device according to claim 1, further comprising:

a block specifying unit for specifying an item block having plural of the instruction items including the instruction item closest to the operation instruction means, wherein

when the position of the operation instruction means detected by the instruction position detection unit is within a prescribed distance, the display control unit changes the display mode of the item block specified by the block specifying unit.

6. The input control device according to claim 5, wherein

the block specifying unit specifies the item block including the instruction item including the shortest distance to the operation instruction means and the other instruction items having the similar functions to that of the instruction item having the shortest distance to the operation instruction means.

7. The input control device according to claim 5, wherein

after the position of the operation instruction means detected by the instruction position detection unit is within a prescribed distance, the display control unit changes the display mode of the item block in accordance with the distance detected by the instruction position detection unit, the item block including the instruction item having the shortest distance to the operation instruction means and the other instruction items having the similar functions to that of the instruction item having the shortest distance to the operation instruction means.

8. The input control device according to claim 5, wherein

when the position of the operation instruction means detected by the instruction position detection unit is within a prescribed distance and the position is not above the display operation unit, the display control unit changes the display mode of the item block including the instruction item having the shortest distance to the operation instruction means and the other instruction items having the similar functions to that of the instruction item having the shortest distance to the operation instruction means.

9. The input control device according to claim 5, wherein

after the position of the operation instruction means detected by the instruction position detection unit is within a prescribed distance and when the position of the operation instruction means detected by the instruction position detection unit is within another prescribed distance, the display control unit changes the display mode of the instruction item having the shortest distance to the operation instruction means included in the item block specified by the block specifying unit.

10. The input control device according to claim 5, wherein

the method of changing the display mode of the item block and the selected instruction item under the control of the display control unit to distinguish the item block and the instruction item from the other instruction items includes changing colors, changing brightness, using highlighted portions, and using blinking portions.

11. The input control device according to claim 5, wherein

the method of changing the display mode of the item block and the selected instruction item under the control of the display control to distinguishing the item block and the instruction item from the other instruction items is enlarging an image.

12. An image forming apparatus comprising:

an input control device according to claim 1, wherein

a process of forming an image is performed in accordance with the information of the instruction item output from the input control device.
