Implement sorting in "Compare List"

Learnability/Affordance

User and Task Analysis

What 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.
