Project 4 (Prototyping & Evaluation)

Introduction

This usability testing session was conducted on 27 June 2025 at the user’s own places in-person using our devices. The goal of the testing was to evaluate the usability of our prototype for the EcoDrop system, focusing on how effectively users could complete key tasks such as : 

  1. Locate E-Waste Drop-Off center 
  2. Schedule E-Waste Home Pickup 
  3. Redeem Eco-Points Rewards 

The prototype was developed using Figma and tested on laptop and tablet. Screen recordings and observation  notes were taken to analyze user interaction. 

A total of 3 participants were involved in this testing session, each representing a different target user group of the EcoDrop system. The usability tests were conducted by different group members : 

  • Testing for User 1 was handled by Niveethita
  • Testing for User 2 was handled by Muhammad Aliff
  • Testing for User 3 was handled by Iman Nadhirah

The following sections include screenshots of our prototype, user briefing notes, embedded test videos, observations and findings from the user testing sessions.

Thank you for helping us test our application.

We are currently testing a prototype of the EcoDrop App, and this is a prototype of an app designed to promote responsible E-Waste disposal. We would like to observe how you interact with the design to complete a few specific tasks. You don’t need any prior knowledge of E-Waste recycling to use the app. The purpose of this test is to identify areas where the design can be improved.

During the session, you will be asked to complete the following tasks:

  1. Locate E-Waste Drop-Off Center
  2. Schedule E-Waste Home Pickup
  3. Redeem Eco-Points Rewards

We’d like you to think out loud as you go through each one. If at any point you feel stuck or unsure, you can say “terminate”, and we’ll move on to the next task.

Feel free to express your thoughts out loud. Your feedback is very important. Let’s begin!

Observations – prepared by Ahmad Wildan and Alia Athirah

During the usability testing session, three users from different target groups interacted with the prototype and performed three main tasks. While all participants successfully completed the tasks, several  usability issues were observed throughout the sessions. 

Task 1:  Locate E-Waste Drop-Off Center

In this task, all the users manage to complete the task smoothly. User 1 signs up first then successfully locates and navigates the map to find the nearest drop-off center. User 2 and User 3 also successfully login and navigate the map for the drop-off center. 

Task 2: Schedule E-Waste Home Pickup

User 1 initially assumed that scheduling a pickup required locating a map first, but then unsure how to request someone to pick up the E-Waste. After exploring the interface, she clicked on the recycle form and filled it out. She successfully submitted the form and was able to track the progress, despite some initial confusion. User 2 completed the task smoothly, he successfully selected E-Waste items and submitted the recycle form. User 3 successfully submitted the recycle form but she did not notice the “Track me!” to track her pickup delivery progress. 

Task 3: Redeem Eco-Points Rewards 

This task was generally completed with minimal difficulty, although minor issues were still present. User 1 was confused about where to redeem points but managed to claim three vouchers successfully. When she claimed the free pickup voucher, she was unsure when the free pickup would happen, as the confirmation details weren’t visible. In contrast, User 2 completed the task with ease, he easily found the voucher icon on the main menu and clicked it to view the list of available vouchers. He successfully claimed a 60% discount voucher and received confirmation information. User 3 also completed the task smoothly, she was able to find the button to claim vouchers and successfully claimed all of the vouchers. 

Summary of Interview Results

After completing the tasks,  each user participated in a short interview to share their thoughts. Overall, all three participants appreciated the clean layout and pretty design of the app. However, they pointed out a few issues with the system. User 1 suggested making the button to be more specific and interesting because it is a bit confusing for her and instructions were not clearly visible. She stated that she will use the system if changes were made. User 2 really like the workflow of the tasks process and highlighting the friendly-user on recycle form. User 3 suggested that the colour of the Voucher icon should be changed because it does not match with the colour  theme of the system. 

Findings – prepared by Ahmad Wildan and Alia Athirah

Based on the observations and feedback collected during the usability testing sessions, several usability issues were identified. These findings reveal the areas  where users faced confusion or delay while completing tasks. Below are the key usability problems along with suggested improvements: 

  1. Mismatch Between Icon Color and Theme 

Problem: Some users think that the choice of colour for the Voucher icon does not match with the theme of the system which is green. 

Suggested Solution: Use a better colour for the Voucher icon , from Orange-Black colour to Green-Black colour. 

  1. Lack of Clear Instructions

Problem: Users were  unsure how to schedule or request a pickup for e-waste , with some trying to use the map first, assuming that was part of the process. 

Suggested Solution: Include a short instruction section or guided flow that briefly explains the steps to book a pickup. A modal pop-up, or onboarding screen can help clarify the process. 

  1. Buttons were Unclear and Unattractive 

Problem: Users felt that certain buttons, especially for claiming vouchers and submitting forms, were not visually appealing or clear in their function. 

Suggested Solution :  Redesign button with  a clear action labels
