Pointer to the future item alert:  We've had a backpack-sized brain scanner [TA 19 Jan], now here's where the sensors read your mind. At TEDGlobal 2010 earlier this month, a researcher named Tan Le developed for her company, Emotiv Systems, a headset costing only a few hundred dollars that can detect controllable brainwave changes to control the motion of virtual objects and electronics using visualization. According to the Emotiv website the use of this headset will be in gaming and EEG research. Droid Systems blog and video.
