Problem Description

• Creating a grocery list is time consuming and frustrating for everyone, especially people with dietary restrictions.

• Looking through items label by label for ingredients you can't eat wastes time.

• Sharing a single paper shopping list between friends and family is hard and sometimes not possible.

• Organizing your shopping list to be able to easily go through in the store to find items is also very difficult.

Study Method

• 4-5 participants for both rounds of testing• Given prototype and asked to complete

taskso Add an item to their list that satisfied their dietary

restrictiono Share their list with another user of the appo Sort the items in their list

Study Results: Lo-Fidelity Prototype

• Check lists are easier to understand than drag-and-drop

• Important features (like the share button) should be easy to find

• More descriptive terms are better than simple ones: "Dietary Restrictions" vs. "Filters"

Study Results: Interactive Prototype

• Even tutorials need some sort of explanation

• Some things make more sense on lo-fi prototypes: horizontally scrolling lists

• Successful tests on one device don't mean the app works everywhere

Future Work

• Backend data for store aisles, pricing info, ingredient/nutritional information.

• Implement remaining features: browsing, in-depth nutrition information, etc.

• Keep user testing!!

Conclusion

Through many rounds of iteration and an adherence to pre-established design principles, we designed a user-focused mobile application to assist people with dietary restrictions get their shopping done quickly and efficiently.
