In the last years, wearable haptic technologies became very promising since they provide the users with tactile force feedback via small and wearable interfaces. However, they have no position sensing thus additional technologies like motion capture systems or expensive gloves are required. Recently, low cost hand tracking systems based on RGB-D cameras have been developed, however they suffer from lighting conditions and occlusions. In this paper we present a sensing glove based on inertial and magnetic sensors for hand tracking which can be combined with cutaneous devices for the rendering of the force feedback, thus producing a wearable sensing/actuation system. The sensing glove does not suffer from occlusion problems, it is wearable and cost effective however, since the employed sensors use the magnetometer to compensate the drift, they are sensitive to variations in the magnetic field. This property makes it challenging to interface the sensing glove with wearable devices since their motors generate variations in the magnetic field. Preliminary experiments showed the effectiveness of using inertial and magnetic sensors for hand tracking. A comparison between using the glove with and without the haptic devices was presented in order to compare the tracking performance when cutaneous devices are used.

Abstract

In the last years, wearable haptic technologies became very promising since they provide the users with tactile force feedback via small and wearable interfaces. However, they have no position sensing thus additional technologies like motion capture systems or expensive gloves are required. Recently, low cost hand tracking systems based on RGB-D cameras have been developed, however they suffer from lighting conditions and occlusions. In this paper we present a sensing glove based on inertial and magnetic sensors for hand tracking which can be combined with cutaneous devices for the rendering of the force feedback, thus producing a wearable sensing/actuation system. The sensing glove does not suffer from occlusion problems, it is wearable and cost effective however, since the employed sensors use the magnetometer to compensate the drift, they are sensitive to variations in the magnetic field. This property makes it challenging to interface the sensing glove with wearable devices since their motors generate variations in the magnetic field. Preliminary experiments showed the effectiveness of using inertial and magnetic sensors for hand tracking. A comparison between using the glove with and without the haptic devices was presented in order to compare the tracking performance when cutaneous devices are used.
