This paper introduces augmented tactile-perception and haptic-feedback rings (ATH-Rings) for immersive virtual reality (VR) interactions. The rings integrate triboelectric and pyroelectric sensors for tactile and temperature perception, along with vibrators and nichrome heaters for haptic feedback. A low-power wireless platform drives these components, enabling high-resolution finger motion tracking and gesture/object recognition using AI. This multimodal system creates an interactive metaverse platform with cross-space perception, offering a face-to-face-like virtual social experience.
