To test the shipping software, I downloaded a 1.41MB file on a free 30-day trial offer from Sensiva. Then I right-clicked my mouse, held down the button, and followed Sensiva's cheat sheet to draw letters or symbols, anyplace on my screen, that keyed to my other applications. (The version 3 software also allows you to customize Web sites--and bypass log-in screens.) For instance, you would draw W to launch Microsoft Word, draw a slash (/) downward to minimize the program you were in, or draw L to insert your signature file in any application. The software has 19 customizable symbols.
Priced at $30, Sensiva works on all flavors of Windows (including 95 and XP) and with all kinds of mice. But draw the symbols just as shown on the cheat sheet. If you don't, Sensiva won't recognize them. From the January 2002 issue of PC World magazine
