I went to the CSUN expo in San Diego today and it was pretty amazing. I've never seen so many blind people in one place and it was great to meet others and talk.

/u/geoffisblind they had canes there with buttons on the handle. One button has the cane emit a red, pulsing light, one button emits a sold white light, and the third button emits a loud alarm sound. It's not perfect but it might be helpful if you're feeling threatened.

There were also many different magnifiers, cctv, and canes. Revolution now makes a cane adapter tip so that ambitech tips can be used on revolution canes.

There were various glasses in development also. One pair that I particularly liked somehow projected the image onto my retina. It was amazing. Another pair takes a photo of what it is pointed at and reads the text to you via earbud.

And finally, there is a music program that works with Braille displays! It also the user to scan or download a music score, play along, play alone, or edit. To scroll they have developed special foot pedals so that your hands can stay on the keyboard.

I'll sort through all my fliers later and post names if anyone is interested!
