Tomorrow’s Grocery Cart

The Brief


Where can I find the hot sauce?” For a personal project connected to a Udemy user experience course I took, I wanted to create an electronic shopping device which would allow users to quickly and easy answer questions such as this. The device needed to be accessible via the in-store grocery cart with an attached scanner. In addition to locating in-store items, the device could allow shoppers to access a shopping list, choose recipes, check-out more quickly, etc. I utilized the Double Diamond design process, along with a UX Roadmap (developed by David Travis), to research and design an app that would allow a user to achieve these goals while shopping.

The Results


After conducting a contextual inquiry with eight potential users and doing rapid prototyping testing with both a paper and low fidelity prototype, I developed an app to be used on a tablet (with scanner) attached to the store’s grocery carts. This app allows users to navigate more quickly through the store, locate desired items, and help with checkout.  Further iteration would involve understanding how the color, typography, form, etc. ties into the UX and UI to convey the supermarket’s image to users, along with an even deeper look into how easily users can manipulate the app.

Key Tools and Deliverables


 

Challenges & Iterations


Testing with the prototype revealed that users were confused how to return back to the home screen.  We changed the upper right logo and symbol to address this. Continuing improvement of this app would involve understanding how the color, typography, form, etc. ties into the UX and UI to convey the supermarket’s image to users, along with an even deeper look into how easily users can manipulate the app. Also, users were not immediately sure how their search results were sorting, something that could be changed in the prototype and re-tested. In addition, use of the scanner with the app was not addresses in my research and would also need to be tested with users.
