（2025·山东·二模）Today’s virtual reality games and content can be absorbing, but they. largely miss the mark when it comes to haptic (触觉的) feedback. Wouldn’t it be cool to just feel an object and perceive the sensation of running your hand over rich fabric in VR?
That’s what researchers at Northwestern University in Illinois are hoping to achieve with their new wearable, a tiny lightweight device that can go far beyond simply vibrating (震动) against your skin to deliver richer haptics using more advanced tech.
“All existing haptic devices really just stick at the skin,”said John Rogers, the professor leading the design. “But human skin is receptive to much more complicated senses of touch. That’s why we created a device that could apply forces to the skin in any direction-not just sticking but pushing, sliding and stretching. With it, we can finely control the complex sensation of touch in a fully programmable way.”
Powered by a rechargeable battery, the device uses Bluetooth to connect wirelessly with virtual reality headsets and smartphones. Its small size and energy efficiency allow it to be worn anywhere on the body or added to existing wearable tech.
Depending on where the haptic is mounted-say, on the back of your hand or on a fingertip-the onboard device delivers information about whether you’re moving quickly or slowly, and in which direction. That makes for more. realistic motion tracking. It helps the sensory feedback component of VR experiences catch up to the realistic video we’ve come to expect when wearing a headset.
Beyond enabling more engaging experiences, Rogers notes they can also assist with other novel applications. “If you run your finger along a piece of silk, it will slide faster than when touching cotton fabric,”he said. “You can imagine shopping. for clothes online and feeling the material.”In another trial, they changed the sound of music into physical touch, so a user could differentiate between tones and instruments by the direction of vibrations they were feeling from the wearable. This tech could also help visually disabled people find their way. Their device represents a transformative force across industries, unlocking vast commercial potentials.
