Touch Panel GUI Prototype

In this case study, we explore the design and development process of creating a touch panel solution to improve the volume control experience in university classrooms. Our goal was to enhance user understanding and provide a more intuitive interface for adjusting the room volume. This case study highlights the challenges we faced, our iterative design process, and the final solution that effectively addresses the problem.

Renamed Volume

We recognized that the term "Volume" might not be universally understood, so we replaced it with "Sound Level," which better conveyed its purpose and was more inclusive.

Iconography

We redesigned the icons to be more intuitive and visually appealing. The new icons clearly represented actions such as volume increase, decrease, and mute, making it easier for users to comprehend and interact with the touch panel.

User-Friendly Layout

The touch panel interface was designed with a clean and logical layout, ensuring that the volume controls were easily accessible and prominently displayed. Clear labels and visual indicators provided users with a clear understanding of the current sound level and adjustments made.

Improved User Experience

Professors and students expressed satisfaction with the new touch panel interface, finding it significantly more intuitive and user-friendly compared to the previous system. The enhanced control over room volume reduced disruptions during lectures, creating a more conducive learning environment.

Increased Efficiency

With the simplified and straightforward touch panel interface, users were able to adjust the sound levels quickly and accurately, saving valuable time during classroom sessions.

Positive Feedback 

Feedback from users highlighted their appreciation for the improved icons, clear labeling, and logical layout, emphasizing the overall success of the design solution.

Lessons Learned

Throughout this project, we encountered several challenges and gained valuable insights:

User-Centered Design: User research played a pivotal role in understanding the pain points and expectations of the users. Incorporating their feedback early in the design process helped us create an interface that aligned with their needs.

Iterative Approach

The iterative design process allowed us to refine and improve the touch panel solution based on user feedback. Regular testing and evaluation helped us identify and address usability issues promptly. Group discussions and voting helped
