Overview
This project was done in the Prototyping course at Tallinn University. I interviewed a colleague to find the problems he faces in his daily life, and then use the design process to create a solution.

Problem
"Where can I dispose of recyclable waste in my city?"
I interviewed my colleague in person, recording the audio and taking notes, and found out this was his main problem.
Pains
There is no information where to dispose of recyclable trash nearby.
No time to go find an appropriate dumpster or other place for waste disposal.
Gains
Easy and quick disposal of recyclable trash
Feelings of self-esteem by contributing to the environment
Solution
User Story 1
As a household member, I want to know the nearest spot where I can dispose of recyclable waste, so that I don’t have to roam around looking for it.
User Story 2
As a commuter, I want to be able to find disposable spots wherever I go, so that I can appropriately dispose of water bottles or other recyclable items.
Persona
Storyboard
The UI as a conversation
In a way, the user interface is a way to communicate with the users, like an app trying to have a conversation with them.
I introduced the concept of the app to a colleague using the persona, user stories, and storyboard. With the context gained, the colleague started talking to the app as if it were a chatbot. And I replied on behalf of the app, pretending I was a chatbot.
The conversation was split into different sections, each representing a screen or a feature of the app.
Low-fi Prototype
Based on the screens identified from the conversation in the previous step, I drew a low-fidelity prototype on paper.
Using the Wizard of Oz method to test the prototype, i conducted user testing with another colleague of mine, recording the interactions and problems encountered by him during the usage of the prototype.
Mobile Usability Heuristics Checklist
I used the 25-point heuristics checklist to evaluate the usability of my low-fidelity prototype.
To improve the design, I considered the following:
May need to include Settings in the app.
The only error scenario is going to next screen, which can be undone by Back button.
Haven't included any instructions/help on any screen.
No plans of using any auditory feedback.
No plans of including favoriting any locations for easier navigation.
Future versions of the app can inform users the locations for different types of recyclable spots.
High-fi Prototype
Conclusion
The prototype can further include features such as adding a new spot by users, spots where bottles can be recycled for money, service like anyone can collect trash from other users' household for disposal, etc.
Treating a user interface as a conversation was new to me. It helps to determine the flow of user interactions through different screens in the app. It could even reveal some interactions that may not be initially obvious. I would consider using this in other design projects.
