Problem
Melbourne’s cafés, restaurants, and landmarks embrace sustainability, but users often overlook it — this project engages and educates through interactive experiences.
I used focus groups to uncover user experiences with geo-location apps and AR, creating personas and storyboards to visualise interactions and guide improvements.
"I use geolocation apps every day, like 'PTV' when I had to catch the train this morning to go to class."
"I like geolocation apps because I can connect with my friends and discover new places on Instagram."
"I have tried AR technology with Pokémon Go. I am very introverted, and this mobile game helped me to get outside to socialise."
"The geolocated apps I use are pretty simplified and easy to navigate. They look the same as every other map."
"I usually find cafes on my Instagram explore page, check the tagged location for details, and if it looks appealing, I add them to my visit list."

Stage 02 : Design development
Turning insights into wireframes and prototypes, then refining them through observed behaviours and usability-test feedback to enhance clarity, flow, and usability.

Hi-Fidelity Iterations
I conducted field testing on Prototype 1.0, gathering insights through pre- and post-test forms, observation, and participant feedback.
Using qualitative analysis and Jakob Nielsen’s 10 Usability Heuristics, I translated these findings into UX-driven refinements that shaped Prototype 2.0.

The ‘back’ button was added to the ‘location spotted’ screen
Pop-up to confirm with the user that they want to exit when the 'back' button is clicked

Stage 04 : Reflection
At the final iteration, I tested the prototype with a second focus group to assess the user experience. Their insights shaped future design recommendations.
During development, I used Figma variables to create seamless interactions, like transforming green stars into collected ingredient icons, and experimented with animations, QR scanner slides and notifications drop, to enhance interactivity.
Insights from field tests, questionnaires, and focus groups informed my design decisions and updates. Overall, the app functions well, though the interface and visual design could be further refined with more time.
