Combined tracking and vibrotactile rendering with a wearable armband

Abstract : We introduce a wearable armband interface capable of tracking its orientation in space as well as providing vibrotactile sensations. It is composed of four vibrotactile motors , able to provide contact sensations, an inertial measurement unit (IMU), and a battery-powered Arduino board. We use two of these armbands, worn on the forearm and the upper arm, to interact in an immersive Virtual Reality (VR) environment. The system renders in VR the movements of the user's arm as well as its interactions with virtual objects. Specifically, users are asked to catch a series of baseballs using their armbands-equipped arm. Whenever one baseball hits the arm, the armband closer to the contact vibrates. The amplitude of the vibration is proportional to the distance between the impact point and the position of the activated armband.
