The haptic provides the sensation that cobwebs pass through your moth, spiders crawl across your face, and the viscous substance splashes on them. But most other oral haptic devices require you to use a bulky attachment, and worst of all, you'll probably need to insert some mechanical part into your mouth. The video demonstration above starts normal enough, and I'll be honest, the narrator almost started convincing me that oral haptics were the virtual reality device I was missing. Extremely easy to connect to Quest 1 and 2 via Bluetooth only, many games support it and it is without a doubt the best vr haptic feedback vest.
The haptic accessories for Meta Quest 2 have gone too far, as the developers have created a device that can simulate real-world sensations in the lips, teeth and tongue. According to them, the mouth is surpassed only by the fingertips in terms of tactile sensitivity, making it a primary target for haptic feedback. However, the FIG design is different, its haptic device being a series of transducers that are placed on the bottom of the visor of the Quest 2.So unless you find a game that supports something like B-haptics, you can't use haptic vests in Quest 2 stand-alone (Pavlov shack has an option for b-haptics and I don't know if it's because I'm just a PC port and I don't know if it will actually work).
