The discussion on flicker fusion frequency (FFF) and human vs. canine perception is fascinating. When building systems that synchronize with human physiology, like the metabolic digital twins I'm currently developing, we often find that 'perceived' seamlessness is highly variable based on cognitive load and environmental light.

While 24-30fps might suffice for basic motion, the biological impact of refresh rates on eye strain (especially for neurodivergent users) is a real engineering challenge. This is why I've been pushing for WCAG 2.1 AAA standards in my latest project; it’s not just about 'seeing' the image, but about minimizing the neurological stress of the interaction itself.
