Erase E-Waste App

UI/ UX Design

Erase E-Waste is a one-stop mobile application designed with the aim of informing university students on the methods to manage e-waste as the current process lacks sufficient information and is not intuitive.

​

Task: A university module individual project with the task of redesigning an entire mobile application to focus on mobile interactions that will enhance user experience.

​

Methods: Contextual Inquiry, Wireframing, Prototyping, Usability Testing, Heuristic Evaluation

Team: Sole UI/ UX Designer

​

Duration: 2 months

​

Tools: Figma

Overview

According to the National Environment Agency (NEA) in Singapore, e-waste has been rising significantly with about 11kg of e-waste being disposed of per person every year. 60% of consumers are unsure about how they can recycle their e-waste.

Problems and Solutions

Problems from the existing application were investigated and solutions were proposed to solve these issues.

Proposed App

Target Audience

  • University students in Singapore

    • Large consumption of electronic devices - average university student owns about 7 electronic devices

    • Known to be tech-savvy - the group with the greatest amount of mobile phone usage

Contextual Inquiry

In-situ observation of 4 participants

  • Contextual inquiry with a think-aloud protocol to observe users' step-by-step actions when using the existing application for e-waste recycling was conducted and questions about participants’ thought processes, motivations and emotions were asked throughout to gain a better understanding of how they felt about the mobile application

​

​Some of the significant responses gathered include:

Low-fi Wireframes

Based on the initial research and investigation, low-fi wireframes were designed to test out the design solutions.

Usability Testing

The Wizard of Oz user-research method was used to conduct usability testing in-person with the low-fi wireframes on a mobile. From the usability testing, 3 significant pain points were brought up:

Mid-fi Prototype

With the feedback gathered, the wireframes were refined to develop a mid-fi prototype.

Some of the key redesigns include:

Heuristic Evaluation

From the mid-fi prototype, a heuristic evaluation was conducted to gain further insight into how the prototype can be improved.

High-fi Prototype

Following the heuristic evaluation, the mid-fi prototype was refined to develop a high-fi prototype.

Constraints

Due to limited time, an in-depth competitors’ research could not be conducted to understand the current gaps in user experience. Furthermore, personas and user journey maps could not be formulated to have a better understanding on the habits and behaviors of our target audience. Further insights would have helped to better tackle pain points.

Future Directions

  • Have a ‘Scan’ icon on the ‘Map’ page for users to scan the QR codes at the e-waste bins, allowing users to understand what types of e-waste should go into that bin with ease

  • Include another function to teach users how they can dispose of unconventional e-waste

  • Include a disclaimer to teach users about certain e-waste parts that are not recyclable
