Q: before you move your hands, do you have conceptual idea that where your hand is going?

tracking is almost solved - VR - but user feels nothing
could we produce physical sensations?

how do you feel sensation on feedback?

communication — EMS

feeling a punch (300ms)

feeling holding a cube

haptics for VR

  1. immersion
  2. information access

Pen, tells how much affordance to use

control the muscles

haptics and emotions

EMS applications

the hand is the interface itself


Daito Manabe teleoperation

EMS/ mechanical actuation
shied chi.16



information access - pure abstract information
there was not a big need of miniaturization, moving around in VR

advantage of mechanics:

  1. precision
  2. super human force

advantage of EMS

  1. light weight, portable, free hands
  2. coverage, think about over softer areas of your bogy

overlap with the body

how does your brain feel?

simulation of being hit, simulation of some more dramatic movement


  1. EMS vs voluntary
  2. EMS vs Mechanical

full overlapping
talk to the brain
emulate everything
device become more humanized


externalize, internalize
feels something is picking up your hands

muscle plotter

intention of the user


increase accuracy

EMS introduces intellectually active

observe analogy

in-depth capability

a way to communication some ideas together

it’s more powerful than just watching, because you are watching and doing
IBM, factory, watching the video or experience
