ADD treatment of the future?
There have been a bunch of products over the last several months that look to read brain waves to control various things like your music or games. A company called Freelogic has a new device called BodyWave that promises to read brainwaves and provide feedback to the user via an armband with sensors.
The company claims that the BodyWave system can be used in Freelogic simulations to start and end the simulations by thought alone. The company is aiming the system at markets where workers have to be attentive like air traffic controllers, police, soldiers, firefighters, and others. This would be a great thing for ADHD people who drift off at times to help them keep on task if it works as advertised.
