Reign in blood: exploring blood as a material for game interaction design

Reign in Blood is an interactive art piece based on intentionally breaking touch interaction for gameplay purposes (i.e., making a game increasingly harder to play by dripping blood on a touch screen). It explores how in-game events can be translated into the real world, further bridging the digital/physical divide in touch-based interaction by exploring alternative forms of interacting with existing technology and extending the notion of tangible interactions. We report on reactions the game created during a public art exhibit and reflect on insights we gathered from the design process.
