Abstract: Grounding of kinesthetic feedback against a user's hand can potentially increase the portability and wearability of a haptic device. However, the effects of different hand-grounding locations on the haptic experience of a user are hitherto unexplored. We present a haptic device design that provides kinesthetic feedback grounded against three different locations on a user hand --- the back of the hand, and the proximal and middle phalanges of the index finger. The proposed 2-degree-of-freedom haptic device is modular, light-weight, and wearable. In different grounding modes, the device can provide kinesthetic feedback along the axis of the index finger, and in the direction of its flexion and extension movements. The device will be used in a virtual environment based study to compare user performance in different hand-grounding modes.
