Guide a friend across the golf course
Your friend is on the far side of the course and the cart path splits. You can see the sheet. They can see the fairway. You steer. They walk.
Use cases
A Guide and a Seeker share one walking room. These are four places where a paper map is hard to follow alone.
Walk someone through an airport
They just landed and the terminal sign does not match the text you sent. You both open the same airport diagram and you call the turns.
Help a parent find the clinic
A parent is in the garage with a paper map of the campus. You are on the phone. You can see the sheet. They can see the doors. You walk them to the entrance you agreed on.
Guide a new RVer to their campsite
It is dusk, the site numbers are small, and the loop road looks the same in both directions. Someone at the rig can see the campground map. The driver follows short cues.
