Haptic feedback that rings true
Résumé
An 18-gram haptic feedback ring can deliver powerful force sensations while detecting multi-directional touch inputs, potentially transforming the way we can interact with digital environments. Imagine pressing a virtual button and feeling genuine resistance, or squeezing a digital object and sensing its stiffness. Despite stunning visual and audio fidelity in virtual worlds, touch remains stubbornly out of reach. Current haptic technologies either deliver weak smartphone-like vibrations or require bulky equipment that makes practical use difficult. Writing in Nature Electronics, Sunkook Kim, Jamie Paik and colleagues now report an 18-gram haptic ring that can deliver up to 6.5 N of force feedback while detecting three-dimensional touch inputs. The device - which is termed OriRing - directly addresses the trade-off between performance and portability that is often found in haptic technology.
