Screen #1 - This is the starting screen. All landmark markers start out grayed out, and selecting them makes them bright. Long pressing displays a picture and some info about that landmark. There are two buttons on the bottom of the screen. "View tours" takes you to a list of tours filtered to only include tours that contain the landmarks you selected (Screen #2). "Create new tour," takes you to Screen #4.
Analysis:
- Learnability
- A lot of text is required to explain actions
- Long presses are hard to discover, as is dragging between points
- External consistency with Google Maps
- Efficiency
- Once understood, the UI is efficient in terms of choosing landmarks you definitely want to see
- There are a lot of steps before you are actually following a tour, which is not efficient
- Long pressing to see info on every landmark might be time consuming
- Safety
- Easy to accidentally include or not include a landmark in your filter by accidentally tapping or double tapping
- Adding or removing a landmark from the filter is easily undone
- There is no way to view all selected landmarks, so there may be selected landmarks that are no longer on-screen
Screen #2 - Selecting a tour from this list brings you to a screen with more detail about the tour, including all of the stops, an estimated time for it to take depending on your method of transportation, etc. (not shown). On this other screen there will be a "Start Tour" button, which will take you to Screen #3.
Analysis:
- Learnability
- The selection of the list of tours will be straightforward and easy to understand.
- Smartphone users are used to this type of UI
- Efficiency
- There are a lot of steps before you are actually following a tour, which is not efficient
- You need to select a tour to see more detail before you can start the tour
- Safety
- Easy to go back if you select the wrong tour
- Easy to select the wrong tour, especially if the preview images and preview landmarks lists shown are similar.
Screen #3 - This screen is very similar to the iPhone directions app. It gives words on the top and a map with your path laid out for you. There are arrows to step back or forward in the directions. You can select a method of transportation as well.
Analysis:
- Learnability
- This will be familiar to users and easy to understand (external consistency with other map applications)
- Efficiency
- The arrows are fast to use, so stepping between steps is fast
- Safety
- Hard to misuse the GPS feature, since the only input is the arrows, which are easy to undo (they are a form of direct manipulation)
- Could be easy to accidentally switch mode of transportation, but it is easily undone.
Screen #4 - This is a map view with a search widget to find locations you may want to add. You drag between landmarks to create your tour, or long press on the map to drop a pin and make a new landmark. On the bottom there is a button to create the tour and give it a name.
Analysis:
- Learnability
- A lot of text is required to explain actions
- Long presses are hard to discover, as is dragging between points
- Efficiency
- Long presses and dragging are efficient and fast to use if you know they're there
- Safety
- Adding or removing a landmark from the filter is easily undone
- When dragging between landmarks, it might be easy to make a mistake, but again this is direct manipulation so it is easily undone
