Project 4: Prototyping & Evaluation
Project 4 focuses on evaluating the usability and effectiveness of the OraPlan high-fidelity prototype through structured user testing. In this phase, we aimed to validate whether the design decisions made in earlier stages successfully support users in managing their time, maintaining focus, and handling task reminders. A functional prototype was developed using Figma and tested with real users to simulate realistic interactions and workflows, allowing us to observe how the system performs in practical use rather than theoretical scenarios.
Usability testing was conducted with six participants representing three key target user groups: university students, fresh graduates, and freelancers. Participants were asked to complete three core tasks-hourly task scheduling, activating Focus Mode, and managing task reminders-while using the think-aloud method. Their interactions were screen-recorded, and feedback was collected through direct observation and post-test Google Form responses. The results showed that many users found the system easy to understand and appreciated the clear access to main features, especially task creation and Focus Mode activation. However, several usability issues were identified, particularly related to navigation clarity, date and time selection, reminder redundancy, and limited flexibility in Focus Mode duration.
Based on the evaluation findings, we identified key design improvements to enhance the overall user experience. These included adding clearer navigation controls such as a “Back” button, increasing the visibility and size of date selectors, allowing customizable focus durations, and integrating task scheduling with reminders to reduce repetitive actions. The evaluation highlighted the importance of iterative design, as real user feedback revealed issues that were not obvious during the design phase. Overall, Project 4 demonstrates how systematic prototyping and usability evaluation play a crucial role in refining interaction flow, improving usability, and ensuring that OraPlan better aligns with users’ real-world needs and expectations.
