Hello.
I have an idea about program that reads GPS data and draws local
path/map while you walk. It could be very useful while walking in
unknown terrain, city or big building complex.
When you would like return to starting point it could show a azimuth
with an arrow. It also could show distance to starting point.
Another idea is to add checkpoints on path with small description and
ability to show azimuth on that points.
Last idea is to add voice commands (directions and distance) to inform
blind user how to return to starting point.
What do you think? I think it's quite simple to do in 4 months. It could
be very useful for ordinary users and for blind persons.
