Show the route to a department, room or service on the big screen, then walk the visitor there.

Share opening hours, visiting rules, events or news where people actually are, instead of waiting for them to pass a fixed sign.

Visitors ask by voice or tap the touchscreen. Answers appear clearly on screen, which helps in noisy lobbies.

Both guide and support people. Alf adds a large display for maps and information; Betty is more compact.
