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. |
Viewing and Ordering Food Screen

After opening the menu from the welcoming screen, the application will go straight into the menu part of the application. It will attempt to mimic a typical menu with all products separated by pages. For each item, there is a description, image, compare button, and an add button. When the use clicks on the image, it enlarges. The user can compare items but clicked on the compare button for multiple items and then clicking the "Compare" icon at the bottom, to open the comparing screen. The user can add items to the menu by clicking on the add button, which would prompt a popup for quantity, size, preferences, and any notes he/she would like. The user can filter which items are displayed on the pages by using the filter tools at the top. Within the Scenario Joe uses the menu to quickly order his drink and orders drinks for the rest of the crew. Jane and Julie are choosing which items to compare and using the filtering tools to narrow all the items down to seafood products. Usability Analysis Learnability |
