Inertial Sensor Based Solution for Finger Motion Tracking

Resumen

Hand motion tracking plays an important role in virtual reality systems for immersion and interaction purposes. This paper discusses the problem of finger tracking and proposes the application of the extension of the Madgwick filter and a simple switching (motion recognition) algorithm as a comparison. The proposed algorithms utilize the three-link finger model and provide complete information about the position and orientation of the metacarpus. The numerical experiment shows that this approach is feasible and overcomes some of the major limitations of inertial motion tracking. The paper?s proposed solution was created in order to track a user?s pointing and grasping movements during the interaction with the virtual reconstruction of the cultural heritage of historical cities.
