Technologies for interfacing an input overlay device with a touch screen display of a compute device are disclosed. A compute device may detect that an input overlay device has been placed on top of its touch screen display. After detecting the input overlay device, the computing device determines one or more parameters for the input overlay device. The computing device may then detect an additional touch on the portion of the touch screen display currently covered by the input overlay device. The compute device can then determine an input of a user based on the position of the touch and the one or more parameters of the input overlay device.
