Had the chance to try to demo a couple of months ago. It was pretty compelling although the "controllers" were pretty bulky.

One thing I have found with haptics is that like VR, it can make you very sick. It has been shown that haptics can cause pretty nasty cases of vertigo[0]. In this study, after using a haptics device for 10 minutes the user started experiencing vertigo which lasted several hours, with mild symptoms persisting for several days. I have noticed many of the same effects using the novint falcon haptic controller. It almost feels as if your hand is being pushed on when in fact it is not.

  I think it's unfair to compare the "haptic" feedback of a person being spun in a cyclone simulator to someone being handed a ball to touch. Are you saying you feel like you had vertigo for several days after shooting the novint pistol?

    On the other hand this proves that malicious software can intentionally harm the user even when the device is no longer in use.

      Only with the user's full cooperation. Video games cause motion sickness in some people too, but we don't worry about malware showing us moving images. You'd just take the headset off, close your eyes or let go of the haptic feedback handset.

      If you take a look at the paper that was linked, users were put in a cylinder that had video displays that simulated spinning. I think we've had this since roller coaster simulators, so your specific point has probably been proven since the 90s now. (I vaguely remember the ESPN World in Baltimore having a "design your own roller coaster" ride that allowed you to build a custom roller coaster and then would simulate you riding it.)

  I've worked with Sensable Phantoms and various other haptic devices and I've never heard of this kind of thing. Interesting that it does occur at all. I've seen papers done using these kinds of haptic systems combined with co-located graphics where the graphics and haptic systems displayed different information. What they found was just how dominant the visual system is and how haptic and proprioceptive were definitely secondary. With a deformable surface you can make the graphics deform more than the haptic surface and people will think it's softer.
