I built Skyway.run with the intention it becomes the go-to app navigating connected buildings in cities across the globe. Every time I hear from someone, they tell me about a new city with a similar network... and also the same difficulties navigating their skyways!

Where should I go next? A few places I've heard so far:

1. University of Minnesota: The Gopher Way

2. City of St. Paul, MN: Skyway System

3. Chicago, IL: Pedway System

4. Calgary, AB, CAN: +15 Network

5. Montreal, QC, CAN: Underground City

6. Dallas, TX: Pedestrian Network

I've been looking at lots of options for making the directions easier to use.

A big reason I keep avoiding the "blue dot" is because indoor GPS loses a lot of accuracy (and worse: sometimes with high-precision inaccurate locations). Instead, I've been wanting to explore a few ideas:

• Mini-map per building, and users manually swipe as they cross over from one building to the next. Like shuffling cards, they can swipe back if they got lost.

• Timer-based blue dot: assume a typical walking speed (or monitor device motion), and trace the directions line as a best effort match.

• Capture "street view" and use AR to compare your device camera to known locations, and show AR-turn-by-turn directions.

• Let me know what else might work!
