Inner-ear mini-actuators for VR verisimilitudeness

  (+9)(+9)

This idea is for tiny electronic actuators inserted into your inner ear to gently nudge individual hairs and thus fool your brain as to the current balance or orientation of your body - designed to add a lifelike sense of movement and acceleration to flight virtual reality systems.

Also, remotely activating this device for a prank will make someone fall over.

fluid in the semicircular canals [csea, Jul 04 2015]

       oh, not bank balance!

       probably that too.
Ian Tindale, Jul 02 2015
  

       Surely it doesn't need to activate individual hairs (and if it can, it’d be a superb hearing aid, and also human-computer-interface for audiophiles) — all that needs to happen is to set up a ‘wave motion generator’ in the inner ear semicircular canals that contain fluid filled ducts. The two ears need synchronisation of course, but it’s only two things to move, not one per hair.
Ian Tindale, Jul 02 2015
  

       In fact…   

       …and I should hand over to someone a bit more medically knowledgeable than I am (i.e., I’m not medically knowledgeable, at least, not without wikipedia nearby)…   

       …but could it be a good separate idea to invent a sort of tiny sheet of sponge that contains a matrix- addressable array of impulse generating termini which sits on top of where all the lost hairs of a person who is now effectively deaf, exciting dormant nerve endings that may still lie in position.

       Magnetic ferrorfluid seems perfect for this. Any volunteers? (I don't know that I want anything foreign injected into my ears).
RayfordSteele, Jul 02 2015
  

       // Any volunteers?//   

       <hand shoots up; leaps out of chair> YESSSSSSSS!!!!!!!! I volunteer [8th]!!!!!!   

       But seriously (relatively). This is an awesome idea. Balance is about the only sense not already catered to by VR, but is arguably one of the most important.
MaxwellBuchanan, Jul 02 2015
  

       We already have this, and it's awesome ....

       OK, but can we inject things into [8th]'s ears anyway?
MaxwellBuchanan, Jul 02 2015
  

       Couldn't we go "down-stream" a little, and do it electrically in the balance->brain nerves?
<Aside>
I get motion sickness, and I always wondered if I could install an "off" switch in said nerve, to stop me feeling ill. </a>

       [Max] Another useful sense to simulate to improve VR would be proprioception, but getting that right may be harder

       Certainly not. Besides, that triggers unpleasant recollections of Sturton's perverted "hide and seek" game at last year's Walpurgisnacht celebration.

       hippo,- I can imagine the problems with virtual proprioception if it acts incorrectly.   

       “Doctor, I’ve got a pain in my third arm”   

       “Where?”   

       “Next door”
Ian Tindale, Jul 03 2015
  

       //unpleasant recollections of Sturton's perverted "hide and seek" game at last year's Walpurgisnacht celebration.// Yes, but you never did find that dormouse, did you?   

       //Another useful sense to simulate to improve VR would be proprioception// But VR is supposed to allow you to move/walk physically, shirley? If you had synthetic proprioception, you would not be interacting voluntarily with the VR.

       This jar feels dusty.
Ian Tindale, Jul 03 2015
  

       You're meant to be on the inside.
MaxwellBuchanan, Jul 03 2015
  

       Even a Möbius jar?
Ian Tindale, Jul 03 2015
  

       You're twice as supposed to be twice as much inside if it's a Klein bottle.
MaxwellBuchanan, Jul 03 2015
  

       Look at you! I made you break your clavicle! PRANKED!
Voice, Jul 03 2015
  

       I wonder if, in the history of the world, anyone has ever broken their clavicle with a clavichord?
hippo, Jul 04 2015
  

       A we getting meaner as we get older?
pashute, Jul 04 2015
  

       No, just less inhibited about expressing it.

       //oh, not bank balance!// Good one, [po]!
csea, Jul 04 2015
  

       Endolymph [link], the fluid in the semicircular canals is ionic, hence should be susceptible to influence by electromagnetic fields.   

       There is therefore a plausible basis for implementation of the idea without resorting to //tiny electronic actuators// and/or invasive replacement of the fluid. [+]

       //Endolymph [link], the fluid in the semicircular canals is ionic, hence should be susceptible to influence by electromagnetic fields. // This probably explains why people fall over after being electrocuted.
MaxwellBuchanan, Jul 04 2015
  

       And also why they don't respond when you call their name.
