Sony patent takes first step towards real-life Matrix
From NewScientist.com
IMAGINE movies and computer games in which you get to smell, taste and perhaps even feel things. That's the tantalising prospect raised by a patent on a device for transmitting sensory data directly into the human brain - granted to none other than the entertainment giant Sony.
The technique suggested in the patent is entirely non-invasive. It describes a device that fires pulses of ultrasound at the head to modify firing patterns in targeted parts of the brain, creating "sensory experiences" ranging from moving images to tastes and sounds. This could give blind or deaf people the chance to see or hear, the patent claims.
While brain implants are becoming increasingly sophisticated, the only non-invasive ways of manipulating the brain remain crude. A technique known as transcranial magnetic stimulation can activate nerves by using rapidly changing magnetic fields to induce currents in brain tissue. However, magnetic fields cannot be finely focused on small groups of brain cells, whereas ultrasound could be.
If the method described by Sony really does work, it could have all sorts of uses in research and medicine, even if it is not capable of evoking sensory experiences detailed enough for the entertainment purposes envisaged in the patent.
...
Elizabeth Boukis, spokeswoman for Sony Electronics, says the work is speculative. "There were not any experiments done," she says. "This particular patent was a prophetic invention. It was based on an inspiration that this may someday be the direction that technology will take us."
