Nintendo DS Touchscreen
This is a 4-wire analog touch screen originally designed for the Nintendo DS.
It is used as a transparent overlay on the screen/surface you would like to control/interact with.
A better word for it would probably be "Transparent Touch Pad", as it can't show images directly.
Readings are taken by putting 5V across two of the pins and doing an analog to digital conversion on the other two pins.
Full X and Y position can be achieved with only 4 GPIOs.
Dimensions: 5,58 x 6,98 cm
