Abstract
An input display device includes a display configured to display an image, a capacitive touch panel attached to the display, a knob that is at least one three-dimensional operation unit on a front face of the touch panel, and a sensing unit configured to measure an electrostatic capacitance of the touch panel and sense an operation on the touch panel based on the measured electrostatic capacitance. The sensing unit senses the rotation amounts of all the fingers touching the knob, and determines that the rotation operation on the knob has been performed when a sensed rotation amount of any of the fingers reaches a threshold value.

An input display device comprising:
- a display configured to display an image,
- a capacitive touch panel attached to the display,
- at least one three-dimensional operation unit on a front face of the touch panel, and
- a sensing unit configured to measure an electrostatic capacitance of the touch panel and sense an operation on the touch panel based on the measured electrostatic capacitance,
- wherein the sensing unit senses rotation amounts of all fingers touching the operation unit, and determines that a rotation operation on the operation unit is performed when a sensed rotation amount of any of the fingers reaches a threshold value.
