Wayfinding is helping people find their way through a physical space. On a screen it usually means a searchable directory plus a route, replacing the printed board that was wrong the day a tenant moved.
Digital earns its place in three situations: when the destinations change often (hospitals, offices, exhibition halls), when the space is large enough that a static map is unreadable, and when the visitor is stressed, which describes most people looking for a departure gate or a clinic.
The caveat is that people orient themselves by landmarks, not by maps. The most common failure is a beautifully accurate floor plan rendered in the wrong orientation, so north is up rather than the direction the viewer is facing. A map that does not match the body's orientation is slower to read than no map at all. Always render "you are here" facing the way the visitor is facing.
Second, print the answer. The route a visitor memorises at the kiosk is gone twenty metres later. A QR handoff to the phone, or a simple step list, is what makes the interaction survive walking away.
