 Are any aspects of the conceptual model confusing? Please list:
1. The conceptual confusion on the Google maps comes when
introducing an address it can send you to a different location with
same street name or home address but different zip code making it
hard to figure it out to the user until it is too late.
2. The physical book of maps are bulky to transport, and several
pages are required to show just an area of interest making it
complicated to take on a walking trip.
3. You only need some minimum map reading skills to use when using
a physical map but when navigating on the Google application it’s
hard to figure it out how it works or when to click to hear the voice
navigation, or how to avoid highways.
