Embodiments include apparatuses, methods, and systems for computing. An apparatus may include a display screen of a computing device, and an on-screen input interface controller co-located with the display screen. The apparatus may also include a receiver co-located with the display screen to wirelessly receive an off-screen input from an off-screen input support device of the computing device. The off-screen input support device may be separately located from the display screen. The on-screen input interface controller may process an on-screen input provided via an interaction between an on-screen input device and the display screen. In addition, the on-screen input interface controller may further process the off-screen input received by the receiver. Other embodiments may also be described and claimed.
