- 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.
...
- Learnability
- The selection of the list of tours will be straight forward straightforward and easy to understand.
- Smart phone 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.
...
- 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.
...
- 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
- Dragging When dragging between landmarks, it might be easy to make a mistake, but again this is direct manipulation , so it is easily undone
Storyboard #2
...
- Learnability
- Clicking the list icon brings up a list of what you were already viewing on the map, which is not obvious (these two views are more linked than that, so maybe they should be presented as such)
- The interface has external consistency with many other "list views"
- The search bar at the top is clearly labelled
- The list items present check boxes, which users are likely to be familiar with
- It is not clear that you need to go back to the map to view the results, so perhaps a “View Results” button should be added.
- Efficiency
- Not as efficient as viewing results on a map (but since the user selected to have the items appear on the map, so it’s acceptable in this case)
- There should be a “check/uncheck all” button in order to improve efficiency
- Long-pressing on a category icon (such as a martini glass for a bar) should give you the option to check/uncheck all items of that type
- Safety
- Not very easy to make a mistake, since checkboxes are separated with large margins
- Easy to immediately undo a “check” operation by clicking it again
- If you check something and then do another search, it’s not clear how you can uncheck something that’s no longer visible
- There should be a “view checked” or “clear all checked” button
...
- Learnability
- External consistency with a typical compass, as well as other applications that take advantage of a compass interface
- Ideally the movement of the compass needle will teach the user that it is actually pointing to the location
- The map provides more information (in a well-known format) if there is any confusion
- There are two mental models being presented here: the compass where the direction to the landmark is always at the top of the screen, and the map where north is always at the top of the screen. Perhaps it would be better to have a map/compass button at the bottom that switched between the two views, so that the user could take advantage of whichever one aligned best with his or her mental model
- Efficiency
- The map recommends the fastest way to get to the desired location
- The compass provides real-time updating of the direction toward the goal
- Safety
- The Mistakes are unlikely; the only action that can be taken from this screen is to click a button at the bottom or find out more about the chosen landmark
- The compass button will always be in the bottom, so you can easily return
- Perhaps there should be a "cancel" button that stops tracking you and pointing you to the next landmark
...
- Safety:
- Requires deliberate actions on the user's part before moving to next screen/part
- No binding actions, easy for user to undo anything they have done.
Screen #2 - Here Torch makes it easy to follow tours with a small map showing the closest landmarks as well as a list/guide of the landmarks they will be travelling to in a scrollable list. This list has a picture of the stop, the stop's name, a small stop description, and an estimate for how much time users on average spend at that specific stop. Users can return to the previous menu by pressing the tab button labelled "Torch" at the top. In addition, at the header at the top, it shows how many stops makes up the tour being shown and how long the whole tour will take. It will also let users easily switch between the transportation modes: walking, public transportation, and personal car (inspired by map views found on most phones).
...
- Learnability:
- Explicit markings for each stop
- Map areas behave as expected External consistency on map areas (no additional learning if already familiar)
- Icons are used consistently and may be already familiar to user
- May be confusing how to get back to main menu
- Not clear what is clickable and what is not clickable
