Ok, so the app doesn’t exactly reads your mind but it visualizes whatever brain waves XWave head gear senses while clamped to your head. The head gear costs $100 and once you put it on, it senses your brain waves and analyzes them to provide some very useful information. The iPhone app is free of cost and interacts with the head gear once it is inserted into the ear phone jack of your phone.
The gadget uses patented NeuroSky ThinkGear technology, essentially sensing analog electrical brain waves and converting them into digital signals that can be displayed on an interface and programmed. The device is currently based on algorithms that can capture signals related to “attention”, “meditation” and physical blinking of eyes. For example, one of the graphics that are displayed on the iPhone app is a ball that you can raise if you really focus your thoughts on any topic or thought. Moreover, the app measures your level of relaxation and dynamically displays it through a shift of colors on the screen.
The app also has a generic visualizer screen that displays through interesting graphics what kind of activity is going on in your brain right now. To clarify again, the gadget reads your brain waves and not your actual thoughts. The device is obviously not a perfect science yet but is definitely a great example of the kind of technology we should expect to see down the road. Over all, it is a great fun app to have if you a extra hundred bucks to spend on the gadget.
