I was given a demonstration of this at the CSUN conference when I visited the U.S., and I agree that it's a very innovative feature. That demonstration was on a Papenmeier Braillex Elba, running Linux. My Baum INKA has optical sensors, rather than routing buttons, above each cell. One means of navigation that could be programmed in its original DOS software was to assign the "next window" command to the last ten optical sensors on the line, and the "previous window" command to the first ten sensors. All the user had to do was to touch a sensor quickly after finishing the line, which did not involve moving one's hands away from the display area. It was quite efficient. The problem with the optical sensors is that unintentional activations are possible when reaching over the display to type on a keyboard behind it, for example. _______________________________________________ This message was sent via the BRLTTY mailing list.
