A side question to this one. Is there any guide-set or set of rules to judge which information is more important than other when designing a map-like mobile application?
When using Google Maps in driving guidance mode, I:
- see a totally useless (from my perspective) information -- street name -- nearly all the time,
- don't see an absolutely crucial information -- ETA -- until the very end.
Here are some examples.
- 190 meters till possible turn and no ETA:
- Less than 150 meters and still nothing:
- Only forty meters for a decision and still no ETA:
- Last "capture", ETA appears when you're already in the process of turning:
Either I am missing something totally obvious (and would really appreciate an explanation here) or the whole ETA functionality has a purely wrong design. From the decision-making perspective I don't need street name at all, but I do need ETA on all the alternatives.
In mobile Google Maps this is made exactly opposite -- unimportant, useless information (street name) very often covers most important one (ETA).
Is there any specific reasoning, guide or rule set:
- in general -- to decide which information is more/less important and thus must be shown above/beyond some other information in mobile apps design,
- in this particular example -- that justify current mobile Google Maps design.
