WriMouCon: Wrist-Mounted Haptic Controller for Rendering Physical Properties in Virtual Reality

Minjae Jo, Dongkyu Kwak, Sang Ho Yoon

Abstract: For immersive Virtual Reality (VR), the need for effective and precise haptic feedback is increasing. This paper proposes a wrist-mounted haptic controller that provides direct feedback to the palm for rendering various physical properties. We conducted various experiments that demonstrated the effectiveness and accuracy of our device. First, we found that our device renders negligible force (0.02N) to the user in the free-hand situation. Second, we confirm that our device renders physical properties with high accuracy (within 6%) by using Force Sensing Resistor (FSR). Finally, we present the minimum force feedback threshold and difference threshold of the proposed device. From the results of perceptual experiments, we suggest a design guideline for using the proposed prototype.
