Apparently, Sony has received a patent on a purely theoretical method for transmitting sensory experiences directly into the brain. Their approach would non-invasively fire ultrasound pulses at various parts of the brain. Details are sparse as the inventor declined interview requests from New Scientist.
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."
