Technology hey...Where will it end?

Just got this from a mate.

"Experts have found a way to trigger an out-of-body experience in volunteers.

The experiments, described in the Science journal, offer a scientific explanation for a phenomenon experienced by one in 10 people.

Two teams used virtual reality goggles to con the brain into thinking the body was located elsewhere.

The visual illusion plus the feel of their real bodies being touched made volunteers sense that they had moved outside of their physical bodies.

The researchers say their findings could have practical applications, such as helping take video games to the next level of virtuality so the players feel as if they are actually inside the game.

Clinically, surgeons might also be able to perform operations on patients thousands of miles away by controlling a robotic virtual self.

Teleported

For some, out-of-body experiences or OBEs occurs spontaneously, while for others it is linked to dangerous circumstances, a near-death experience, a dream-like state or use of alcohol or drugs.

One theory is that it is down to how people perceive their own body - those unhappy or less in touch with their body are more likely to have an OBE.

But the two teams, from University College London, UK, and the Swiss Federal Institute of Technology in Lausanne, believe there is a neurological explanation.

Their work suggests a disconnection between the brain circuits that process visual and touch sensory information may thus be responsible for some OBEs.

In the Swiss experiments, the researchers asked volunteers to stand in front of a camera while wearing video-display goggles.



Through these goggles, the volunteers could see a camera view of their own back - a three-dimensional "virtual own body" that appeared to be standing in front of them.

When the researchers stroked the back of the volunteer with a pen, the volunteer could see their virtual back being stroked either simultaneously or with a time lag.

The volunteers reported that the sensation seemed to be caused by the pen on their virtual back, rather than their real back, making them feel as if the virtual body was their own rather than a hologram."
