Off the top of your head, whatâs the best way to increase immersion while using virtual reality? Flawless, controller-free hand tracking? Direct brain integration? Maybe some kind of smell-o-vision? Nope, sorry, the answer weâre looking for is âliterally being able to feel spiders crawling on your face.â
Thatâs the goal, believe it or not, of the Future Interfaces Group, an âinterdisciplinary research labâ at Carnegie Mellon University. Okay, their work isnât just about spiders, but eight-legged freaks play a large role in the groupâs latest study (h/t PC Gamer), wherein they experimented with producing âmouth hapticsâ by way of an ultrasound array attached to a regular VR headset and directed at the userâs face.
âTodayâs consumer virtual reality systems offer limited haptic feedback via vibration motors in handheld controllers,â the Future Interfaces Groupâs paper reads. âRendering haptics to other parts of the body is an open challenge, especially in a practical and consumer-friendly manner. The mouth is of particular interest, as it is a close second in tactile sensitivity to the fingertips, offering a unique opportunity to add fine-grained haptic effects.â
As shown in the video above, the technology was used to simulate several, arachnid-related scenarios. Who wouldnât want to feel the wispy caress of webs on their lips, or a spider try to forcibly enter their mouth? Why even play a video game if you canât experience the tactile sensation of a spiderâs guts splashing against your face after shooting it with a flare gun? Apparently, not even internal anatomy like teeth and tongues are safe from this ultrasound arrayâs ânew and interesting VR experiences.â
Other examples include feeling the water as you drink from a fountain and sensing the wind breeze past you while riding a motorcycle.
âWe found that mouth haptics boosted immersion, realism, and other important factors in virtual reality experiences,â the paper concludes.
Itâs honestly a pretty cool piece of work, spider stuff aside. Not only would this ultrasound array give developers a whole new sense to seriously consider when making games, itâs also compact enough to work with most existing VR headsets without inconveniencing the user. A lot more study and research is required until this is ready for a consumer market, of course, but even for someone like me with little interest in virtual reality, itâs hard not to imagine the possibilities
