Set up and navigation in the Active@Home exergame. The hardware of the Active@Home exergame consists of four inertial measurement units (IMUs). For movement evaluation, participants wore the sensors at wrists and ankles. Color and size of the bracelet helped to distinguish the position of each IMU. The IMUs were connected via Bluetooth to a HDMI dongle. This dongle was inserted into a television and provided the exergame software. The game interface was presented on the TV screen. By pointing the IMU on the right wrist horizontally to the TV screen, a “hand mouse” got activated for navigation through the game.
