In this study, a fingertip force display device that uses negative pressure is developed. The device can control the resisting force against a finger’s motion by regulating the negative pressure in an air chamber processed in the device. Information about the position of a finger is obtained with a Web camera using AR-Toolkit library, and the resisting force is controlled based on the fingertip position (velocity), which shows the capability of the VR-oriented application and mechanical impedance task. The effectiveness of the proposed system is verified through experiments.
