(The crossed fingered modes > might be tricky...) I've never seen the signs for +, -, \ or |. I'm sure they exist, but they may be more involved than single finger/hand positions. I also think despite the advantages of using an existing hand gesture language, ASL is designed to be seen and doesn't take full advantage of all the possible finger/hand positions that could be used as part of a gesture input device. However, if it could be designed to use full finger/hand/arm gestures you could input words faster than typing, which would be really wonderful. -Paul
