That pen looks interesting but I couldn't find anything about it using GPS. It can use Bluetooth or USB to transfer data to a computer. One problem with using it for recording chess games is that you must use its own "dot paper". It will not work on the standard chess scorebooks. If scorebooks could be printed on "dot paper" it could be a viable alternative to the Monroi someday.
GPS uses satellite signals to determine location. It's accurate to about 10 feet for civilian use. That's not accurate enough for any board I have.
I am looking at these DGT chessboard and how they are so unaffordable right now for hobbyists and non professionals. However its so obvious that is clearly the future of chess.
I had a look at a topic here about USB chess boards as well.
Recently while looking up new devices for my evernote, came across an interesting product called livescribe echo smartpen. Very reasonably priced.
Its an interesting technology where you write on a special paper and the pen stores the movement of the handwriting. Then using GPS technology, the handwriting is transferred to evernote app and turned into text.
This could be technology used in future in chess equipment as well.
A GPS enabled chess pieces could be used to transmit moves to the computer on a special chessboard and used to play with Fritz or Analysis.
Any thoughts ?
