OUTCOME

How can we make healthy snacks more accessible to college students through vending machines in the University of Washington?

We defined 6 core tasks

  1. Choose healthier snacks in machine

  2. Receive personal curation of snacks

  3. Experience streamlined payment method

  4. Locate vending machines

  5. Access nutritional information of snack

  6. Conduct Snack-search

Together, we created the paper prototype of the vending machine interface and the mobile app prototype
We made changes to our design based on user feedback. For example, we initially used 1 for navigation button, but it turned out 2 was easier to understand.
I made the information architecture in Illustrator.
I created several versions of the logo
