  The final analysis shows that the mixed-reality game improved learning by almost five times more than the screen-only alternatives, both in the mouse-controlled and physically controlled conditions.
Paper Finding: Our 2x2 experiment found no evidence that adding simple forms of hands-on control enhances learning, while demonstrating a large impact of physical observation.

  The final analysis shows that the mixed-reality game improved learning by almost five times more than the screen-only alternatives, both in the mouse-controlled and physically controlled conditions. Not only that, but students enjoyed the game more in the mixed-reality conditions. They also determined that simple physical controls like shaking the tablet or pushing the earthquake button did little to improve either learning or enjoyment of the game.
Paper Context: Immersing children in the real world with computer vision-based feedback appears to evoke embodied cognition that enhances learning. Our 2x2 experiment found no evidence that adding simple forms of hands-on control enhances learning, while demonstrating a large impact of physical observation. A general implication for educational game design is that affording physical observation in the real world accompanied by real-time interactive feedback may be more important than affording simple hands-on control on a tablet.
