Smart Cart Redesign
Final Prototype
Heuristic Evaluation
What I Was Looking For
This evaluation was based on Jakob Nielsen's 10 Principles for Interaction Design. The smart cart was ranked on how big each problem was (with 1 being not a problem and 4 being a huge problem).
Nielsen’s principles revolve around design aspects that affect both usability and visual appeal.
Conclusions
This cart could be a helpful but it needs some improvements.
Biggest issues: User Freedom, Mistake Recovery, Documentation
Project Scope & Workflow Diagram
Scope
A feature that uses the shopping cart to access a previously made list would improve this cart.
Connect to App
Having users sign into their Wegmans account gives the opportunity to access the list feature, see stocking data, item locations, & familiar search features.
New Features
The new features will connect the cart with the Wegmans app & incorporate the Wegmans list feature & stocking data.
Workflow
After deciding what my project would encompass, I made a workflow diagram of how the new smart cart would function & how the user could navigate through each aspect of the cart.
Wireframes
Style Guide
What’s Included
After I finished wireframing, I added style to my designs that emulated the current Wegmans app with color and icon styles.
I made guides for color, typography, iconography, and button and card styles. I also outlined my grid system and all the spacing on each frame.
Final Comps
Takeaways
Research works.
By using the device and observing other shoppers, I gained insights beyond what I could get from just looking at the device. This helped me create a new feature that is truly impactful.
Physical & digital work together.
In this project, the physical design of the device and the interface on the screen impacted the user experience. Creating a feature that helps make the physical device less of a problem helps bring them together to work well.
