Can a paper-based sketching interface improve the gamer experience in strategy computer games?

Abstract

The field of sketching interface design in regards to video game is relatively young and has not been investigated in great depth. Freepad is a custom paper-based MIDI musical interface. We describe an extension to Freepad that supports user customization for real time strategy games. Using only a webcam, a pen and a sheet of paper, players can design their own interface by drawing shapes and linking them to simple or complex actions in the game. In an user study, we use this extended Freepad to explore the potential of sketching interfaces in strategy video games. Our results indicate that using Freepad improves the efficiency of players and their enjoyment in this kind of games.
