Researchers at Sungkyunkwan University, in collaboration with EPFL, have developed a novel wearable haptic device called OriRing. This ring-shaped interface uses a 3-axis force sensor to provide users with realistic sensations of the weight and stiffness of virtual objects when interacting in VR. Unlike traditional haptic systems that rely on simple vibrations or bulky mechanisms, OriRing is ultra-lightweight (about 18 g) and capable of sensing multi-directional forces through micro-structured polymer surfaces, allowing precise tactile feedback directly at the fingertip.
Testing showed that users can not only perceive object properties like size and hardness but also adjust virtual object characteristics in real time using just finger movements. Because of its high force-to-weight performance and compact wearable form, OriRing offers advantages over glove-type devices and has potential applications beyond VR and gaming, such as rehabilitation, medical use, and remote robotic control. The research was published in Nature Electronics and marks a step forward in creating more immersive and physically grounded human-computer interaction technologies.
