Haptic Ring Tech Lets Users Feel Touch & Force In Virtual Reality & Augmented Reality

Описание: An Ultra-Light Haptic Ring Bringing the Sense of Touch to Virtual Worlds

Wearable human–machine interfaces are transforming how people interact with virtual and augmented reality by adding the sense of touch to digital experiences. While visual and audio technologies are already advanced, realistic tactile and force feedback remains challenging due to the size and weight of most wearable devices. Heavy and bulky systems limit comfort, portability, and everyday use.

Addressing this challenge, a research team led by Sunju Kang has developed a lightweight haptic ring that weighs only 18 grams yet delivers advanced force sensing and feedback. The ring offers three-degrees-of-freedom force detection, allowing it to sense and apply forces in multiple directions, closely matching natural finger movements.

A key innovation is its origami-inspired structural base, which enables efficient force transmission in a compact form. The ring also features a soft force-sensing skin capable of detecting both normal and shear forces. This skin combines a laser-patterned layer with pyramid-shaped microstructures and four resistive sensing pixels, ensuring linear sensitivity and fast response.

Powered by soft pneumatic actuators and integrated with inkjet-printed bending sensors, the ring can provide kinaesthetic force feedback of up to 6.5 newtons. This compact and comfortable design opens new possibilities for immersive VR/AR, rehabilitation, training, and advanced human–machine interaction.
