now I have played around a little with navit and tried to reduce the
recalculation when speed is under 4.
It's my assumption that a walk is at last about 5 km/h, thus I added
some lines of code to handle this case.
But before I am really do too much that propably has been done I would
The speed that triggers a recalculation of the displayed map is about
more as 2.
Should this be done a little bit more ?
Or could it be done by a 'lowpass' that increases the trigger about
half the average speed (three or four times measured)
if the average is more than the result of the increase ?
The decrease should be done similar (about some below the average).
This will reduce the amount of recalculations a lot I think.
A question beside. I want to try my changes on my FreeRunner for a
How to get changes into the MokoMakefile built of navit.
Should I create a patch to be applied in a prebuild step ?
I have seen several directories per user that do something I don't
Any further help out there ?
Another idea: What about a real voice, recorded from someone to
replace the synthetic voice ?
(There are not so much combinations I think)
