Excellent writeup. The post mostly talks about navigation in indoor spaces and U1-to-U1 communication, but I hope it fixes Google/Apple Maps not knowing which direction I'm pointing my phone and constantly re-updating.
That's odd; when I visited Japan this past spring I used Google Maps on my iPhone practically everywhere while walking, and the biggest helpful UI element was the blue compass arrow that would point wherever I was facing. It was generally quite accurate as I can't even remember it ever really pointing a different direction from where I was actually pointing.
I have it happen in downtown Chicago, although I think it is more that the positioning is not reliable enough that I’m sure which street I’m currently facing.
Yeah, for some reason the compass chips or Google Maps sucks so bad with orientation-showing. I suspect it's the latter, because Google Sky Map works great with my phone.
Apple Maps already have a mode which knows where you're pointing your phone (based on built-in compass). As far as I can tell, Google does not, and it figures it out when you move.
