In the Discover Tour you can decide whether audio should start automatically at spots. If this feature is enabled, a matching audio guide starts automatically as soon as you get close enough to a spot.
The audio radius is important here:
A smaller radius means audio starts only when you are very close to the spot.
A larger radius means audio starts earlier.
This is especially helpful when you want to explore on foot or by bike with as little tapping as possible.
The current setting is intentionally flexible:
adjustable audio radius
auto-start can be turned on or off
This lets you decide whether you want to browse freely, read more actively or be guided as automatically as possible.
