摘要： Provided is an input display device (100) capable of detecting a pulling operation on a three-dimensional operation portion (130).
An input display device (100) according to the present invention includes a display (110) configured to display an image, a capacitive touch panel (120) configured to be attached onto the display (110) and include at least one three-dimensional UI portion (130) on a surface of the touch panel (120), and a detection unit configured to detect an operation on the touch panel (120). The three-dimensional UI portion (130) includes a pulling portion (134) imitating the shape of a pulling type switch (30), and the detection unit determines a pulling operation by detecting a change in a capacitance in response to a change in a distance from a finger (U) touching the pulling portion (134) to the touch panel (120).-
