Read your mind? There's an app for that

An iPhone app that lets you read your mind? Really?

The plastic headband, which costs around $100, has a sensor that presses against the user’s forehead and communicates with a free XWave iPhone application that then shows your brain waves graphically on the iPhone screen. As you focus your mind on a task the graphics are changed — a ball may move higher for instance, or your state of relaxation may be indicated by changes in a pulsating color, which moves towards blue as you become more relaxed.



Brainwave detection is powered by an NeuroSky eSense dry sensor, which provides a brain-computer interface (BCI) to sense even faint electrical impulses in the brain and convert them to digital signals that are sent to the iPhone. Previous applications of the NeuroSky technology include computer games and toys. In XWave an algorithm is applied to the brain rhythms to convert them to graphical representations of attention and meditation values.
