This paper discusses haptic force rendering on a multi-finger electrostatic passive haptic feedback system using a force-direction sensor. The system consists of transparent electrode on an LCD monitor and multiple pads for user's multiple fingers. The system can render haptic feedback force using electrostatically induced friction. However, the previous trial suffered from the sticky-wall problem, which is commonly found in passive haptic systems. In this work, we developed a force-direction sensor that can be integrated into the pad with a diameter of 30 mm and responds to more than 0.2-N pushing force. A wall-rendering experiment shows that the force rendering using the force-direction sensor can reduce stickiness of the virtual wall.
