We introduce and formally evaluate smartcasting: a smartphone-based Ray Casting implementation for 3D environments presented on large, public, autostereoscopic displays. By utilizing a smartphone as an input device, smartcasting enables “walk up and use” interaction with large displays, without the need for expensive tracking systems or specialized pointing devices. Through an empirical validation we show that the performance and precision of smartcasting is comparable to a Wiimote-based raycasting implementation, without requiring specialized hardware or high-precision cameras to enable user interaction.
