This document traces the evolution of video game controllers from early button-based controllers to modern gestural interfaces like the Wii and Kinect. It begins with a genealogy of game pad shapes showing how they evolved from simple brick shapes to more ergonomic designs. It then outlines the advantages and disadvantages of gestural interfaces compared to traditional controllers. The rest of the document describes various studies conducted on gestural gaming including analyzing how people explore game spaces, perceive realism, and behave while playing gestural games. It concludes with discussing prototypes created and design recommendations for seamfully integrating gestural controls.
