Wearable Cat Ears Controlled By Your Brain [video]

That's just a step off. I think the exciting thing is opening up a line of thought and possibility that we'd have another dimension to wearable computing.

Instead of just LEDs on nerd shirts, or tracking your day to day habits, we may have avenues for dynamic expression as well.

keyboards are nasty for neural interfaces. "text" is a complex symbol based input. really Hard to parse out of electrodes on your skull. I am working on a neural interface for a wearable computer, a brain controlled "mouse" is possible but really clunky. We really need to re-design how we interact with a computer to make a good brain-computer interface. I am not sure what that is going to look like yet, but I am going to in about a year or my thesis is going to be very boring.

Already exists: put fingers on keyboard; think of what you want to type; allow brain to move fingers.
