Claim 6:
7. A detection device comprising:
a plurality of first electrodes extending in a first direction;
a plurality of second electrodes extending in a second direction that crosses the first direction; and
a controller configured to (i) select, as first detection electrodes, two of the first electrodes and two of the second electrodes positioned outermost in a predetermined detection region, (ii) select, as first driving electrodes, at least one of the plurality of first electrodes and the plurality of second electrodes not selected as the first detection electrodes, and (iii) detect a target in a non-contacting state from signals expressing capacitances acquired, by applying a voltage to the first driving electrodes, from the first detection electrodes,
wherein the display device includes an autostereoscopic display configured to project, based on a first input image and a second input image for two viewpoints, different images to a left eye and a right eye of an observer that are aligned in a predetermined direction, and a space image-forming element that includes a plurality of light-reflecting elements that reflects light from an object by a first reflective surface and a second reflective surface that are orthogonal to each other and that forms, in space, a floating image corresponding to the first input image and the second input image projected by the autostereoscopic display, and
wherein the plurality of first electrodes and the plurality of second electrodes of the detection device are provided on the space image-forming element.
