Design Problems Identified:
- Outdated interface design
- Slow response time and frequent pop-ups
- Lack of clear instructions for produce scanning
- No undo or back function
- High dependency on staff for resolving issues
Research Methods:
- Personas (including real and fictional users)
- Think-aloud protocol
- Usability testing with real-world users
Design Solution – SmartScan Checkout System:
- Dual Basket System: One for produce (green) and one for non-produce (blue)
- RFID Bulk Scanning: Instantly scans all tagged non-produce items in one action
- Integrated Produce Scale: Weighs items as they are added
- AI Produce Recognition: Identifies fruits/vegetables visually
- Interactive Touchscreen UI: Clear navigation, accessibility options, and Everyday Rewards integration
- Bagging Feedback: SmartScan detects bagging and offers visual/audio guidance
- Multilingual Help and Tutorials: Integrated into touchscreen UI for inclusivity
- Motion Graphics & Animations: Optional onboarding animation for first-time users
Outcome:
SmartScan not only improves efficiency and accuracy but also creates a more inclusive and intuitive checkout process. The project culminated in a foam board prototype, interactive UI design for iPad, and a full user flow animation to simulate real-world use.
