Hello and thank you for help us with our project, OpenMenu! This is ______, ______, and _____. Picture this: You are going out to a restaurant on a Friday night with a couple friends. When you are seated, you notice that instead of menus, your waiter has grabbed tablets instead. Your waiter informs you that the restaurant is trying out a new electronic ordering system. The purpose of this new ordering system is to make ordering and waiting at restaurants faster and more efficient and to entertain customers while waiting for their orders to arrive. To help us test the system, we're going to ask you to do some scenario tasks. |

Description of Problem | Type of Usability Issue | Possible Solution |
|---|---|---|
User did not understand what "Compare List" button did (older parent) | Affordance | Change wording |
User did not know how to remove an item from their order (older parent) | Learnability | Adding more information of their order in the actual menu (Better Affordance). |
User assumed that they can sort the "Compare List" by clicking on the label (such as "Price") (college student) | Efficiency/Affordance | Implement sorting in "Compare List" |
User did not know how many of an item they had already ordered (waitress) | Affordance | Display the number of times an item has been ordered on the "Add to Order" button |
User thought help button was for device/interface help (older parent) | Affordance/Learnability | Change wording to be more specific to waiter/waitress help |
User didn't know you could click on an item to view more information on the product (older parent) | Learnability/Affordance | Make the picture/description of the product look more clickable, like a button |
User thought the Help page was help for the application instead of calling a waiter over for help wasn't sure if "Add to Order" sent in their order or if they had to send in their order separately (older parent) | Learnability | Change "View Order" to "View and Send Order" |
User removed items by accident on the Order Screen (older parent) | Efficiency/Safety | Add a confirmation prompt before removing the item to make sure the user didn't click it by accident. |
User found the radio buttons hard to click for the tip calculator (college student) | Efficiency | Instead of three radio buttons, make it three regular buttons that instantly change the tip once clicked on the percentage. |

User and Task AnalysisWhat We Learned When we thought about what we wanted to get out of 6.813, we wanted to learn more about making technologies easier to use for populations that normally don't interact with technology. With this in mind, we decided to make a menu system because menus are used by both technologically advanced users and users who don't even own a computer. This was highly risky but we believed that it would be a great learning experience so we carried on. We learned that interviewing people who would be typical users of our product are extremely beneficial in learning about that the user, the user's technical abilities, and the user's desires in our product. Performing our task analysis was useful throughout the production of OpenMenu because it gave us goals we wanted to accomplish that we can always keep in mind. What We Would Have Done Differently We believe that this process went extremely well, and we wouldn't have changed much. We felt as through the user groups we chose were ideal for our product and the tasks we choose were valid for OpenMenu. |
