A Force Feedback Glove Based on Soft Actuator

Abstract

The invention relates to a force feedback glove based on a soft driver, comprising a soft driver and a control system of the soft driver, the soft driver can bend and generate elastic force; one end of the soft driver is connected to the back of the hand, and the other end is connected to the fingertip through a rigid link , so as to realize the transmission of force; in the free space state, within the graspable range of the fingers, the resistance generated by the bending of the soft actuator does not exceed the limited value; in the constrained space state, the soft actuator is inflated and bent, and the force generated by the soft actuator The connecting rod is transmitted to the fingers to generate feedback force, which simultaneously meets the dual requirements of force feedback gloves in free space and constrained space. The force-feedback glove can increase the immersion of users interacting with virtual reality, allowing users to touch and manipulate virtual objects in an intuitive and direct manner, which is lightweight and low-cost, while still providing realistic tactile feedback.

Description

technical field [0001] The invention relates to a force feedback glove, in particular to a force feedback glove based on a software driver. Background technique [0002] To enhance the immersion of interacting with virtual worlds, glove-like haptic devices have been developed. Users can touch and manipulate virtual objects in an intuitive and direct way by using dexterous manipulation and the sensitive perception of human hands. Existing force feedback gloves are usually composed of rigid connections and structures, which are very bulky. Wearing them for a long time will cause fatigue and are expensive. Moreover, the principle is simply to limit the movement of fingers to achieve force feedback, and cannot provide continuous feedback force. The change. Its weight and high price are extremely unfriendly to consumers and developers. Users cannot get a good experience and cannot afford such an expensive price. Therefore, consumers and developers urgently need a light-weight,...
