In case you've ever wanted to dabble in telepathy, NeuroSky Inc. has prototyped a new sensor that lets you control your cellphone with brainwaves. Based on similar medical technology, the system can roughly measure brain relaxation and concentration to pass on appropriate commands to a cellphone. Though the system is made up of several parts right now, NeuroSky plans on integrating everything into a small chip in the near future. I hope the final version of this product includes a brain inebriation detector. Otherwise, I pray for all of us cellphone users already prone to drunk dialing. [Tech On]
