Developing "Eyes-Free" Gadgets and Applications 85

The New York Times is running a story about Google engineer T. V. Raman, who lost his vision at age 14 but didn't let that stand in the way of his interest in technology. In addition to modifying a version of Google's search engine to give preference to pages that were more compliant with accessibility guidelines, Raman is now working on making cell phones easier to use without needing to look at them. "Since he cannot precisely hit a button on a touch screen, Mr. Raman created a dialer that works based on relative positions. It interprets any place where he first touches the screen as a 5, the center of a regular telephone dial pad. To dial any other number, he simply slides his finger in its direction — up and to the left for 1, down and to the right for 9, and so on. If he makes a mistake, he can erase a digit simply by shaking the phone, which can detect motion." Raman and a co-worker, Charles Chen, are also attempting to extend various phones' ability to read back scanned text to include signs that are anywhere in the phone's field of view.

  • You could probably translate different things about the text into different audio cues. Bigger text? Louder reading. Stereo headphones could also make the reading come from the direction of the sign. As image recognition gets faster and more accurate, I'm sure a number of different audio cues could tip a blind user off with clues about the environment. I am sure the usefulness of this will go well beyond blind users.

    I think that a cell phone with just buttons on it and braille lettering would suffice, provided that the voice navigation is really good. An added advantage is that having no screen can make for very thin and attractive devices, if aesthetics is something of a priority for them.

      One of the down sides to hardware that has no screen on it is that there is not a sufficient market for general use, and as a result the cost to the consumer is significantly higher. Braile readers for example end up being hand made because there isn't a sufficient demand to mass produce them, but the result is a display that's one or possibly 2 lines of text, that costs a couple hundred to a couple thousand dollars to produce.

      Part of the idea of what Raman is doing is taking existing consumer hardware and applying software solutions to make them more usable to the blind.

      A similar solution would be to use a cell phone to convert the words a person is speaking into text that a deaf person could read. You could build into it language recognition and translation and the deaf person on the bus next to you on your next tour of Europe, Japan, China, etc. may get more out of what is going on around you than you do.

      A screen free MP3 player may sound like something that a blind user would appreciate, especially if the control hardware, and the audio menus were well designed. The big problem becomes one of what all the device can do. Adding a camera to a device like this seems somewhat counter intuitive from a consumer goods perspective, even if the hardware cost were just additional pennies. How about gps location hardware. Again just pennies, but to build it into that MP3 player doesn't seem to make all that much sense, does it. Add in a compass and an accelerometer, and you have a navigation aid that a blind user could use to get almost anywhere with.

      The thing is that pretty much everything described is in a G1, so really adding usability for the blind is primarily a matter of plugging into the user interface with something that converts text to speech and where possible images to text. Both of those are partially solved problems. The part that's still difficult is getting it all tied together, and making available sufficient processing power to make it operate cleanly.

          Maybe true - but does any touchscreen phone currently on the marker have this damn useful feature?

          • All regular touchscreens (not phones) do. You can configure them so that a "double-tap" opens, for example, the context menu right under your finger, or launches a specific app with a specific interface at your fingers' location.

            Calling this innovative is like calling a blank white board innovative because "you can write anywhere - you're not constrained by the lines."

      Voice recognition is annoying enough for sighted people. For the blind who place greater reliance on audio feedback from the device it's a pain in the ass.

Or keep talking until the end and then try to fix all the errors through voice control... fun, fun, fun.

First of all, you still have to hit a button to activate voice recognition, then you have to say the name you wish to dial, then you have to keep saying no to all the names the phone thought you said.... And that's only if the number is programmed into the phone already. My experience with voice-to-number dialing has been even worse than voice-to-contact.
