Look Ma, No Hands!!!
Wednesday, April 29th, 2009For many of us, keeping up with the latest technology can be challenging enough. In fact, some of us are just learning how to Tweet on Twitter…..say that 10 times as fast as you can.
So imagine not only learning the technology, but using your mind to control it. That is exactly what researchers at the University of Wisconsin are doing.
The smart folks at UW are Tweeting by using only their minds to spell the message…..they are literally spelling with their brains. How you say? By using a brain-computer interface that monitors electrical impulses generated by your thoughts to turn brainwaves in to letters that in turn spell words that in turn create a Twitter message.
So how does this work? The brain-computer interface is basically a keyboard that is displayed on a computer monitor. The letters flash in sequence. You stare at the letter you desire for the message and when the letter flashes, your brain reacts as if to say….hey wait a minute, that was my letter! The interface picks up the change in brain activity and then “types” the letter in to the message. You then begin focusing on the next letter. Amazing.
Some of you that are like me have heard enough about Twitter in the last week….they are everywhere. So why did the UW folks pick Twitter? Ease of use. Twitter is simple…much simpler than an email. Believe it or not, sending an email requires quite a few decisions……addresses, cc’s, subject lines and so on. Twitter is 140 characters and that is it. Type your message and go. The only downside is that Tweeting with your brain waves can become tiresome as you will max out at approximately 10 letters per minute.
This type of communication could be a lifeline for people that are “locked-in”. When a person is locked in, their brain is perfectly fine, but their body is not. They can think and want to communicate, but cannot. Communication is the number one need for someone that is locked in. Think about not being able to communicate with those around you and now you can. This is a fantastic combination of technologies that will provide immediate benefit. Think about the future as well……clearly, this is the first of many steps for this concept……
