Screen #3 - In map view, the users can see all the landmarks close to the location they chose and they can add or remove landmarks/spots from the menu on the side. They can simply click on a landmark to add it to the list or they can drag and drop it to remove or add to the list on the side. At the top it will show how many stops they have selected and the estimated time to see all of them. The user will have to long-press a landmark on the map to see a description of that spot. To add a landmark to the map, the user must long-press an area of the map that doesn't already have a landmark. Once the user has made their tour, they can click the follow tour button and will be taken to screen #2. In this screen, the user can still return to screen #1 by pressing the Torch tab in the top left corner.

- Learnability:
- Explicit markings for each stop
- Detailed descriptions for each stop, but only after long-press which may not be obvious (although consistent with other map applications)
- Map areas behave as expected (no additional learning if already familiar)
- Icons are used consistently and may be already familiar to user
- Ambiguity about how to drag and drop by long-pressing on a stop
- Ambiguity about how to add a stop
- May be confusing how to get back to main menu
- Hard to discover actions like long-presses and dragging
- Not clear what is clickable and what is not clickable
- Efficiency:
- Not clear how to add location
- Easy to form a tour by clicking or dragging and dropping
- User can easily switch order of stops
- Long pressing to see info on every landmark might be time consuming
- Users can quickly and easily add landmarks to map or tour if actions are known
- Safety:
- Easy to add landmarks by accident
- Not clear how to remove landmarks from map
- Easy to remove or add or undo things dragged and dropped onto tour
- A lot of direct manipulation so easy to make mistakes but also easy to undo
