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

Smark, an integrated experience consisting of a intelligent vending machine and a mobile app that makes healthier snacks more available to college students.

We studied vending machine issues and trend information from academic papers and journals
Doing contextual Inquires helps understand how people currently use vending machines
We conducted online survey to find out people’s daily vending machine experience
Early sketches of the app UI
We used affinity diagrams to help us decide the key tasks.

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

Next Steps
  • Development of app experience with real data and complete navigation

  • Usability studies of working app prototype and iterations of design
