It has to be a only matter of time before we quit having to use the traditional interfaces between humans and devices, i.e. sight, sounds, and touch, and go directly into a brain interface. It would certainly be preferable to make this interface wireless (!!).
For the longest time, I've joked about a standard plug embedded in our belly button. This headband idea seems way better.
I am wondering how easy it will be to start using the brain band interface for surfing, channel selection, volume control, etc.. I would think that a lot of processing power will be needed if there will be support for complicated actions. Perhaps it will support drop down menus and could use a possible voice input to augment the control and features supported. It would lead new meaning the to phrase "thinking out loud"..
