Abstract: This research paper introduces a soft VR glove that enhances how users interact with virtual objects. It seamlessly integrates discrete modules for sensing and providing haptic feedback, encompassing tactile and kinaesthetic aspects while prioritizing wearability and natural finger movements. The glove employs custom-designed flexible bend sensors with carbon-impregnated film for in-situ joint angle tracking, simplifying the sensing system and enhancing portability. A multi-modal haptic feedback approach includes an innovative pneumatically actuated tactile feedback technique and a motor-tendon-driven kinaesthetic feedback system, providing exceptional realism in virtual object manipulation. The glove’s kinaesthetic feedback lets users perceive virtual objects’ size, shape, and stiffness characteristics. Psychophysical investigations demonstrate how readily the users acclimate to this hardware and prove each module’s effectiveness and synergistic operation. This soft VR glove represents a minimalist, lightweight, and comprehensive solution for authentic haptic interaction in virtual environments, opening new possibilities for applications in various fields.
