About This Design The third design we developed is based on a tab system, with the main tabs being Menu, Order, Payment, and Entertainment. The tab system allows direct and quick navigation between features. The main screen will simply be an image that the restaurant wants to use as a cover screen. Quick arrows and notes will be serve as tutorials on each individual tab. |

Description The order tab is where the user will be able to review the items they have decided on and also add preparation notes or special requests. Users will also be able to delete items from this tab. The order can be sent by pressing “send my order.” Within the Scenario The four friends will simply look over this page to make sure it is what they ordered, adding preparation notes as they wish. They will press the send button to place their order. Usability Analysis Learnability The order tab is great in terms of learnability. First, there is a list of all items and preferences that the user has selected. It is also very simple in that there is only the list and a send order button. Efficiency It is also very efficient, mainly in its simplicity. Items that are not wanted can be deleted by unchecking. There is only a list and a button so not much in terms of efficiency issues. Safety The only issue with safety with this order tab is that sent orders are final and can only be changed if the waiter/waitress is called over. |
