Yes we made a design for a small Ship Control Unit as advanced hardware input controller last year.
Trouble was, we could not find any manufacturer who was prepared to produce it in low volumes.
Now a 3rd party is developing a low-cost Ship Driver unit, see http://raildriver.com/products/shipdriver.php
They plan to bring it to market in 2008.
As for our professional console unit, we are developing another version with more navigation screens.
Radar, conning, ECDIS, and several panels with buttons.
It will run on 2 or 3 PCs instead of just one.
Its price, as you might expect, will be too high for non-professional users.
It will however be a good alternative for full mission bridge simulators that now cost several $100k or even several $ million. And it will be small enough to be used on board.
