Hi Tony, thanks very much for these two apps. I have just downloaded
them on to my phone and will enjoy using them both outside and in. Janet

Blind Compass and Blind Bat - new apps for the blind
Hello,
My name is Tony and I wrote two iPhone apps for blind people and
recently I published them in AppStore.
Blind Compass is a compass app specifically designed for blind people.
I was surprised that such an app didn't seem to exist before - or am I
missing something? First, it reports your heading continuously by
varying pitch, so that even with not much musical training you can
easily memorize how the right direction sounds like, and you'll be
able to walk in straight line just by listening to your direction.
ALso when your heading crosses North,East, South, or West you will
hear that spoken to you.
I recommend to use Blind Compass with bone conductance bluetooth
headphones. Bone conductance headphones don't block ears, so that you
can hear sounds from the environment, as well as audio feedback from
BlindCompasss.
You can also have your heading spoken by either pressing button in the
app, or if you are using bluetooth headphones, you can press play
button once.
Second, Blind Compass allows you to lock your direction. Either press
lock button in the app, or press fast forward button on your
headphones, or double press play button on your headphones, and your
direction will be locked. You will hear auditory feedback guiding you
back to the original heading. If you allow Blind Compass to use
location data, then it will also count distance travelled from the
point where you locked your location. This way you can cross vast open
space without fear of veering.
Another app I wrote is Blind Bat - and it is designed to help people
to learn echolocation. Maybe I'm not that good at it myself, but I
wanted to play around with it, so I designed an app that would make
ideal click, whatever that might entail. You have a few parameters you
can adjust and the app would generate click sound that conforms to
these parameters. You can specify mean frequency, bandwidth and
duration of click.
If anyone is interested in source code:

Let me know what you think of them!
