Better audio only navigation #4368

Open Matthias84 opened 7 years ago

Matthias84 commented 7 years ago

usecase

I often drive by bike and after I setup my route, I (try) to just follow the audio-instructions by earphones, when I put the smartphone back into my backpack.

current

In bicycle mode, you only get very few and general instructions. As a result, you have to check the route from time to time, because one isn't sure, if you are still on the right way / which crossing is the right one / ...

improvements

I know, that this are pretty complex ones, that might result in their own tickets and discussions. But IMHO it's good to get an overview and get an more general idea, if this is interesting (and possible to realize) for the devs:

use more objects/details (more human style)

Usually an human co-driver would give you very easy to understand hint's, not limited to streetnames. For example: 'take the way right next to the postbox / advertising / shop / ...'Follow the unpaved road trough the forest', ' Follow the road for the next 3 places', 'It's the yellow house over their!'

Similar approach is PERRON navigator (slides) but POIs such as cafes might be very rare at countryside. An general approach might be to use unique (small) objects, or objects attribute differences (which the driver is able to recognize quickly), to explain the course.

more 'you are on the right way!'

To avoid periods of uncertainties, it would be nice, if the driver gets feedback from time to time, that he's on the way ('Still just follow this road'). This also includes (unused) crossing, or leaving roads, etc.

Indicate longer silence

You will have longer tracks, where no instruction is needed (just-follow-the-road). It would be nice, if you could get an audio-feedback, which indicates that there will be no further action needed for some time and that you just cycle. For example ('Just follow the road, the next instruction comes in about 15 minutes.')

I know that esp. the parameters are highly subjective, but they might be evaluated, if we do an survey. For example presenting an Mapillary track and ask people to mark at which point they would like to get which instruction.

Just one last word: OSMand is a pretty cool piece of code :thumbsup: :smile:

Regarding only your subclause "more 'you are on the right way!':

I opened a related issue (https://github.com/osmandapp/Osmand/issues/4326) (only relevant for bike, too).

I think your point can actually be solved by enabling the option repeat the current guidance every X minutes (don't know where exactly right now), which I always use. The missing part for me is the "You're wrong, turn over".

sonora said, they are discussing the issues.

This is a huge request, but let me try to slice it this way:

Matthias84 commented 7 years ago

Thanks for your review and the tips, I will try the existing options to tweak the audio instructions.

@sonora I'm not sure if A.I. and neuronal networks is an solution to just everything :wink: IMHO it's pretty ok to create an catalogue of hints and fake the 'intelligence' just with a few patterns. I guess this would be an pretty nice step towards an more natural & easier navigation that benefits from OSM micromapping

Long unplanned detours when cycle touring is a no no. "You have missed your turning" instruction would be invaluable. Please reinstate for cyclists.

@Matthias84 Maybe you could show us an example. Take a screenshot of an example area, and tell us, what the mapping software should use to give hints, and when (for example a post box is small, could be hidden behind a parking car, therefore announcing the post box to early wouldn’t be of help). Maybe you could even do three or four examples.

Criteria and ideas could be taken from Orienteering maps (i.e. maps that work without (street) names), for example

Matthias84 commented 6 years ago

Do you recommend an sep. ticket(s) to outline this specific idea?

sonora commented 6 years ago

Some items imay be easier to fix than others, so yes, chopping this into small pieces, showing how to reproduce, and stating what the expected behavior is or even how it could be fixed could certainly help.
