For a viewing task involving ADM on a 1080p image, what is the relationship between distance and image height?

In visual tasks regarding Acceptance Display Metric (ADM), particularly with a 1080p image, the relationship between viewing distance and image height is crucial for optimal clarity and detail perception. As the distance from the screen increases, the image height must also increase to maintain the viewer's ability to perceive details effectively.

When viewers are positioned farther away from a display, a larger image height allows them to utilize their field of vision better and minimizes the risk of visual strain. The human eye's ability to discern detail decreases with distance, so to compensate for that decline in resolution at greater distances, a larger image height ensures that important visual information remains within the optimal range of vision.

Additionally, maintaining a specific image height relative to distance is essential for achieving an immersive and effective viewing experience, especially when it comes to critical tasks that require attention to detail, such as those involving ADM.

In contrast, when distance increases without a corresponding increase in image height, details may become less distinguishable, leading to a reduced viewing experience. Thus, the relationship is one where higher distances indeed necessitate higher image heights to ensure that the content remains visible and clear to the viewer.
