Query: Some Experimental Results of Relieving Discomfort in Virtual Reality by
  Disturbing Feedback Loop in Human Brain   Recently, great progress has been made in virtual reality(VR) research and
application. However, virtual reality faces a big problem since its appearance,
i.e. discomfort (nausea, stomach awareness, etc). Discomfort can be relieved by
increasing hardware (sensor, cpu and display) speed. But this will increase
cost. This paper gives another low cost solution. The phenomenon of
cybersickness is explained with the control theory: discomfort arises if
feedback scene differs from expectation, so it can be relieved by disturbing
feedback loop in human brain. A hardware platform is build to test this
explanation. The VR display on a Samsung S6 is blurred while head movement is
detected. The effect is evaluated by comparing responses to the Simulated
Sickness Questionnaire (SSQ) between a control and experimental condition.
Experimental results show that the new method can ease discomfort remarkably
with little extra cost. As a result, VR may be used more widely in teaching
(like foreign language, medicine). It's also reasonable to expect likewise
merits in other VR applications.
