With Wearable Computing Ring Jason Maderer introduces us to a technology in the form of a ring which lets us transfer information from one medium to another. In this case from your fingers to a computer. This could be adapted.
Say to a finger where you could write long hand and have the symbols you draw out be reproduced on a screen. Maybe even the touch sensitive screen on your computer or tablet, but not just those screens already design to be written on but any touch sensitive screen.
Another matter to think about.
