Storyboard Design 3:
Pros:
Learnability:
- The list of suggestions is sized so that the last suggestion in the list hangs halfway off of the list, an affordance to indicate that the user can scroll down the list of suggestions
- Once a suggestion has been chosen, all of the immediately available options related to their selection will appear on explicitly labeled buttons in the following screen (see pictures 2, 3, and 6)
- The selectable list format is consistent throughout the entire application, whenever the user is presented with several options on the same screen, they will be displayed in the same list format with the same number of options shown in each menu.
- The four category buttons each have an icon on them that indicates a category that the user can toggle and those same icons appear next to the suggestions on the list to indicate the category that that suggestion falls under. (see pictures 1 and 5)
Safety:
- The list lit can be scrolled up and down, the direct manipulation allows the user to go back if they pass over a suggestion that they may have been interested in.
- Since the user has the option to delete a suggestion permanently, we added an undo delete button that adds the most recently deleted suggestion back to the pool of suggestions. (see picture 4)
- The menu presents the user with a “show deleted suggestions” that presents a list of the deleted suggestions that the user can choose to add back to the suggestion pool. (see picture 4)
- The application utilized the back button that is built into all android phones to allow the user to go back to the previous menu page.
Efficiency:
- This design will be able show several suggestions at the same time, more suggestions than the others since the suggestions only appear as text in a list.
- When the application shows a list of places that the user can choose to find more information about, the Yelp rating will appear in the list so that the user won’t have to open each location suggestion to find out it’s rating. (see picture 6)
- While you’re making a decision, a map showing your distance from the location appears above the list of options. (see pictures 3 and 7)
- Pressing the Google Maps button opens up the Google Maps application with the address of the currently selected suggestion already filled in.
Cons:
Learnability:
- The undo delete option doesn’t appear unless you press the menu button which may not immediately occur to some users.
- Since the buttons at the bottom are not labeled with text, the user may not understand what the buttons correspond to.
- Since there aren’t explicit instructions, the user may not immediately understand the purpose of the buttons at the bottom of the screen.
Safety:
- The red x’s function isn’t apparent until you actually use it which will end up deleting the suggestion next to it.
Efficiency:
- Since there are more suggestions shown on the screen, the targets will be smaller and it will be a relatively more difficult pointing task.
- The user will have make at least one click to see an image related to the suggestion that they wish to explore
