The three properties of a usable meeting point
There is a reasonable amount of thought available on how to design a wayfinding system for an airport and almost none on how to describe a single spot inside one to a person who will read the description once. It turns out to be a narrower problem than it sounds, with a small number of requirements, and almost every failure is a failure of one of them rather than something exotic.
It has to be findable without a map, visible from a distance, and impossible to confuse with a second one of the same kind. A coffee chain at the end of a hall meets all three. A pillar number meets none of them.
The test is whether somebody could find it having read the description once, on a phone, while walking. If it needs a second reading it is not a meeting point, it is a set of directions.
- Findable without a terminal map.
- Visible from at least twenty metres away.
- Unique within that hall.
