The brain is really good about reassigning stimuli that doesn't make sense to virtual events. Having something distinct from your controller vibrating (which already covers a lot of virtual interactiosn that don't make physical sense) will be nice, as well as for abstract stuff like UIs e.g. a light wrist squeeze when you're hovering over interactable elements.

That being said, vibration is definitely easier and cheaper than a wrist squeeze bracelet, so I'm not sure what the cost/benefit of this thing is over the status quo
