The Social Apps Lab at CITRIS focuses on harnessing mobile game-play to address social issues. As a graphic designer for the Social Apps Lab during Fall 2011, one of my projects involved prototyping and designing an iPad-based game that would encourage senior citizens to exercise more by walking. The resulting game, called BingoWalk, overlays a 5 x 5 tile grid on the user's surrounding area and combines both physical movement and a bingo number generator to create a dynamic game.
