In the long term, this has great potential for improving communication - imagine being able to visualize something and show it to other people instantly, rather than having to try to draw it or put it into words.

For example, it could greatly speed up teaching if both the student and teacher were equipped with an advanced version of this device, since the teacher could immediately see and easily correct any mistaken visualizations the student had.

It could be the human-to-human equivalent of going from 56k to broadband.
