Why is user testing considered vital in display design?

User testing is considered vital in display design primarily because it identifies usability issues and ensures that the design meets the actual needs of the users. This process allows designers to observe real interactions with the display, receiving direct feedback from users regarding their experience. By engaging users in testing, designers can uncover pain points, confusion, or obstacles that may not be apparent through theoretical analysis or expert reviews.

The insights gained during user testing help refine the design, making it more intuitive and effective in conveying the intended information. It acts as a crucial validation step to confirm that the display is not only visually appealing but also functionally sound and user-friendly. This user-centered approach ultimately enhances overall satisfaction and efficiency in the use of the display, ensuring that it serves its purpose effectively.
