Virtually There !


Published in JFWTC   inhouse journal Vol3 Issue 3 2007

Two articles in two separate issues of Science,   constitute very captivating reading.  July 27th issue of Science carries a  review on the enormous possibilities  a  Virtual World can provide. William Sims Brainbridge, the author  is with the Information and Intelligence systems Division of the National, Science Foundation, USA.  Aug.24th issue has a scientific report on “Video ergo sum: Manipulating bodily self consciousness”,  in simple terms “ out of body experience”. The authors  Bigna Lenggenhager  and Tej Tadi  are from Laboratory of Cognitive Sciences, EPFL, Lausanne Switzerland Thomas Metzinger has affiliations with both Guttenberg and Goethe Univ., Maiz and  Olaf Blanke is from the Dept. of Neurology University Hospital, Geneva.
The first article deals with “Virtual World”.  Most of us have had a dose of this  through “Matrix “a movie which powerfully presented  this concept. The story is set in the 2199   when mankind is reeling under the threat of  a complete take over by intelligent machines.  The machines, in an effort to subjugate the mankind,  have designed the Matrix, a virtual world and the trapped, hapless humans believe that they are living in the real world. The saviour Neo, fights against odds to snap the spell and bring deliverance to all. Much earlier in  a Walt Disney movie, TRON,  an Master Control Program (MCP) digitizes  Flynn, the slighted scientist and the MCP condemns  him to play virtual games   till death. But ultimately Tron rescues Flynn by destroying the MCP.  Even prior to this we have had glances of a virtual world in “Alice in Wonderland”.
Currently World of Warcraft (WoW) and Second Life (SL) are the popular online role-playing  internet games set in virtual world.  Bainbridge argues that virtual world need not be confined to cybergames and science fiction, but can be effectively used to  generate quantitative data for social , behavioral and economic sciences. In fact National science Foundation, USA has provided support to set up two educational virtual worlds “River City” and “Quest Atlantis”.  Stretching further, Bainbridge suggests that one could, perhaps   get a peep into elusive concepts such as “Self and identity” by cleverly manipulating the various “avtars”. 
And that is where the  investigations of  “Video  ergo sum” team snugly fit in. Simulating an expansive three dimensional  ambience is one thing and being in there as a “virtual body” is altogether different matter. How does self awareness manifest itself in such ambience? The team set out to seek answers through  a  carefully  designed clinical experiment,. They simulated a virtual reality around participants and  conducted a modified version of the “rubber hand  Illusion” experiment. (A cleverly designed  experiment which tricks the brain into accepting the rubber hand as one’s own). 
The present  experiment involved a three dimensional  rear view   of the  participant himself and synchronous and asynchronous multisensory inputs such as vision and touch.  The experiments per se were very simple; but had to be carefully  conducted. Analysis of participants’ responses has led the team to conclude that  the brain can be cleverly tricked into being in an “ out of body” state.  Conflicting  multisensory signals led the  participant to feel the image seen in front is the  real self.  The team believes the temporo-parietal junction in the brain  has a big role to play in inducing the  “out of the body experience”. 
But what is relevant here is the fact that  through conflicting sensory signals and appropriate imagery  “there, that is me”  feeling can be generated.  As Bainbridge suggested, the potential lies far beyond the boundaries of the entertainment  zone.   Are we getting closer to understanding ourselves through a virtual presence in a virtual ambience?
