Activ8 is a system of three physically interactive digital games: See-Saw, a balancing game for Glass; Jump Beat, a music beat matching game for Glass; and Learning To Fly, a Kinect game where users fly a virtual bird through obstacles by flapping their arms aka two-player Flappy Bird clone. In addition to whole-body movement, we capture heart rate patterns by attaching a pulse sensor to Glass to make a connection between the user's physiological state and their context of interaction. Each game uses easy-to-do actions like balancing, jumping, and flapping arms. Leveraging features of existing digital casual games, our games have simple rules, are intuitive and easy to learn, and can be enjoyed in small intervals of time.
