Brain Controlled Virtual World for the Disabled 57

Posted by Zonk from the you-know-you're-thinking-metaverse dept.
Galactic_grub writes "New Scientist Tech has a story about a virtual world that paralyzed patients can explore using their thoughts. The set-up connects a Brain-Computer Interface (BCI) to virtual reality so that a person can 'walk' through it, simply by thinking of moving their legs or their left or right hand. Electrodes are attached to their scalp and electroencephalogram (EEG) readings are used to navigate, or control an avatar. The story includes a video of the experiment."

    My wife spent a while caring for paraplegics and helping them to adjust. Most of these were young males hurt in mining accidents. Being able to have fantasies about walking is probably low on their agenda and probably serves little useful purpose. Being able to have realistic sex play is probably far more desirable and beneficial to the their health and wellbeing.

      You're probably right. When I was a fledgling nerd who couldn't get laid, I still cybersex0red, because it was better than nothing.

      On the other hand, my tackle was in working order, so at least I could occupy myself when I was done. Yeah, that's it, when I was done.

    • This is being used to advance the technology of Mind Control, not to make a VR video game for paraplegics.

      In this way, the system can be trained to identify the distinctive patterns of neuronal activity produced when they imagine walking forwards, or think about moving either their left or right arm.

      The technology might be used to help people who have experienced a stroke recover greater control over their movements, suggests Christoph Guger, of Guger Technology in Graz, who helped develop the EEG part of the experimental set-up.

        "I know I'd rather be six feet under than lay in a bed for the next 50-70 years."

        I think that's the whole point of this tech. To give some sort of social life to those who are both immobile and without the real life support network to have a fufilling life inspite of their physical limitations. And before you knock this "social life" too much, consider how many people spend the majority of their time in WoW or EVE chatting or helping friends, completely by their own choice. I could think of nothing better for establishing a good game community than to adapt it to a demographic that would likely use the game as a primary means of social interaction. And if I only ever know them as the high level character who helped me out when I was a newbie and who is quick on the chat lines with a joke or a helpful suggestion, maybe that that would be just fine with someone who is unable to be helpful or chatty IRL.

      Before too long compared to what? The lifespan of a human? Not likely, it'll probably be another 5 or 6 years before it gets into the homes of disabled people, much less a normal person. It'll probably be at least a decade before it becomes commonplace in homes without someone who can't use another input device. However, if this turns out to be like speech recognition in accuracy and speed, it may take closer to 20 or 30 years.

Sure, the reliability of it is probably terrible right now, but the machine could be made to filter out random fidgeting signals (similar to what's done with micro-surgical equipment today to cancel surgeons' normal trembling), well enough to have a mobile viewpoint in the real world with cameras, microphones, and speakers.

More capabilities could be added to these devices if controlling them becomes easier.
