Computer Control, by Bug and by Brain

electric_mongoose writes "NewScientistTech has a fascinating story about a paralysed man who can control a computer and robot arm using electrodes implanted in his brain. The electrodes measure neural signals generated when he concentrates on trying to move one of his paralysed limbs and software translates these imagined gestures into the movement of an on-screen cursor or a robotic arm. Other researchers have also revealed a way to dramatically boost the efficiency of similar brain implants in monkeys." If you don't have a handy human brain to play with, 9x320 writes points to a report on LiveScience of Wim van Eck's graduation project: a computer game similar to Pac-Man controlled, not by conventional computer code, but by the brain of an insect. From the article:"Instead of computer code, I wanted to have animals controlling the ghosts. To enable this, I built a real maze for the animals to walk around in, with its proportions and layout matching the maze of the computer game. The position of the animals in the maze is detected using colour-tracking via a camera, and linked to the ghosts in the game. This way, the real animals are directly controlling the virtual ghosts."

    How do they do to make critters chase PacMan? Or they just don't and wonder around in the maze? I didn't find it on the article.

    So from TFA about the insects controlling the ghosts, this doesn't sound as ground-breaking as the first FA... I mean sure the insects are "controlling the ghosts with their brains" but there really is no interaction with the computer at all... The insects are just recognized by the camera who then moves the ghosts in the game correspondingly... Isn't that just optical recognition of colors? Why over-hyped... Though I'm glad to see the advances being made towards better prosthetic limbs. My roommate lost his arm (right below the elbow) in a rock-crusher accident about 8 months ago and we're all still waiting for the day when we get the Star Wars quality prosthetic limbs... :D

    The 'virtual ghost' is not controlled directly by the bugs' brains any more than my computer is controlled by my brain. There are other physical interfaces present. This story was made up to be sensational and actually provides no news at all, other than some bored kid with a webcam and several tortured bugs.
