Taking VR to a Whole New Level: Virtual Sense of Touch

Virtual reality technologies have allowed us to have very realistic human experiences through visual and auditory stimuli that replicate our sensations associated with the physical world. The most common VR and AR systems specifically target aspects of life we can see or hear; however, the progressive and innovative development of virtual sense of touch has the power to take the VR world to a whole other level.

Scientists have created a device that stimulates the sense of touch using a combination of vibration, pressure, and motion. The lightweight and soft sheet of electronics that adhere to the body can be described as “skin-integrated wireless haptic interfaces for virtual and augmented reality” [1]. From gaming and entertainment purposes to helping amputees feel the shape of an object they’re holding, the possibilities of virtual touch reality are vast and wide spreading. 

Virtual reality technologies have played a big role in advancing the gaming and entertainment world. By incorporating touch sensitive controllers and gloves, users can now feel like they are a part of the video games they’re playing. Reactive Grip controllers use touch feedback to enhance video game interactions such as the kick of a gun, stretch of a slingshot or bow, the impact and resistance of striking an opponent with a sword, the contact and inertia of manipulating an object, or the tug of a fish when fishing [2]. 

One technique, known as funneling, produces a sensation of touch that feels like it originates in the empty space between a person’s outstretched hands. A VR headset creates the illusion of a wooden dowel with a white marble that bounces sporadically, creating vibratory sensations felt by your hands with imaginary objects [3]. 

Wearable devices and wireless technologies are not only useful for VR, but for physical rehabilitation as well. Researchers across the U.S. and China created a robotic arm with a specialized patch that allows amputees to feel the sensations of objects they pick up on their arm. When touchscreens are involved, individuals can trace patterns onto the screen so that their loved ones can feel it on their own skin. The research team has plans to develop other versions that provide slight cooling, warming, or even dripping sensations, so that wearers can have a more realistic experience with the objects they’re holding. They also believe these technologies could help benefit stroke patients who have to relearn how to swallow. Individuals can choke if their actions aren’t timed right in the breathing cycle, but a mechanical component at the base of the night could help detect where patients are in their exhalation to let them know the exact time to swallow [4].

From feeling the coldness of winter while immersed in a virtual world to stimulating the sense of a loved one’s touch through social media, this new technology sheds light on a whole new world of opportunities. Aside from the fun and games that virtual touch reality can bring, this technology can completely change the lives of people who have suffered from strokes and accidents. As these virtual touch technologies continue to hit the market, people are able to experience even more sensations in the virtual world beyond audio and visuals.
