Design 1: Using Menu as an Analogy
| Panel |
|---|
In our first design, we wanted to use a paper menu as the metaphor for better learnability. However, it does limit our functionality and causes less internal consistency. |
Welcoming Screen 
| Panel |

This is the initial screen that the use will see. It will display a tutorial of how to use the tablet on the left and side, and a picture of the main menu of the restaurant. There is a little animation of a page flip for an experienced user to recognize that in order to open the menu, the user can swipe and "flip" open the menu. Within the Scenario Joe thinks that this tablet will be easy to learn so he wants to skip over the tutorial. Everyone else decides not to listen to Joe and quickly skims the tutorial. Usability Analysis Learnability If the analogy to a typical paper menu works well, it would be easy to pick up how to view the items on the menu. The user can use the tutorial on the left hand side page to learn how to use the tablet quickly. Efficiency The tutorial is not necessary and experienced users can skip over it by opening the menu immediately. There is also a little "open me" tab on the bottom of the menu that will help the user recognize how to open the menu. Safety This should not be an issue for this task. However, if the user ever wants to view the tutorial after opening the menu, then can access it by the help button on the view menu. |
