ABSTRACT:
An input control device and an image forming apparatus capable of providing 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 element (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 element 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.
