Hi
With seven years and dozens of applications i have found following:
- There is no gps solution that fullfills all needs and preferences. If
someone manages to build such application it would be too complex for
most users.
- User knows better when and what kind of information he/she needs.
automatic announcements are helpful for crossings and destinations or
when user gets out of route - ie next route point is not ahead.
- User interface should be fast to use. Pressing one button (or image
of a button) should suffice in most cases. Users have different
preferences and a set of user-definable function keys is desirable.
- Bellls, whistles and other audio pollution is not needed, neither extra
verbosity. 100 meters is obiously a distance and 90 degrees is not a
temperature.
Storing own points is critical. Storing own routes is important.
Exchangin routes and points with other users is important too.
- Exploring around current location or any other location is very
important.
- Magnetic compass is handy for pedestrian use.
- Address announcements - especially those implementations that just pick
a nearby address and claing you're on that spot - are quite pointless.
Road crossings are much more reliable and accurate way to pinpoint one's
location.
- POIs are nice to know but sometimes out-of-date. Also such
resources as Foursquare has a lot of garbage that have no real use.
- Route calculation is over-emphasized feature. Firstly only few
blind people really travel themselves every week on unknown areas and
secondly route calculation and guidance for blind users is much more than
just announce the turnings. For example how to find the road is user
starts from off-road location; howto fin the next route point; how to get
notified if user get lost in the route; how to find
an off-road destination?
Offline maps are faster to access but are also more prone to get
out-of-date. They also take some space but for example Finland takes
about 350 MB, quite minimal with current memory sizes.
- To me price is not an issue. i can pay for example $ 100 per year for a
working gps solution.
