Description: Field testing in the realm of augmented reality (AR) is a critical process that involves evaluating AR applications and technologies in real-world environments. This type of testing allows developers and designers to observe how their applications perform in everyday situations, where factors such as lighting, movement, and user interaction can influence performance. Through these tests, usability issues, technical errors, and areas for improvement can be identified that would not be evident in a controlled laboratory setting. Field testing is essential to ensure that AR applications not only function correctly but also provide a smooth and effective user experience. This process includes collecting data on user interaction, assessing the accuracy of virtual elements overlaid in the real environment, and measuring the system’s response to different conditions. In summary, field testing is a fundamental stage in the development of augmented reality applications, as it allows for the validation and optimization of technology before its public release, ensuring it meets the expectations and needs of end users.
