With the rapid advances in computer hardware and graphics techniques over the last several decades we are now able to simulate increasingly complex physical and light matter interactions and produce incredibly realistic images and interactive scenes. We must, however, pay significant attention to how these are perceived and interpreted by human visual system. While our vision is highly effective in the everyday sense, there are many evolutionary adaptations and peculiarities that technically make the system inaccurate and prone to misinterpretation. It is also the case that some elements of visual scenes are of much higher importance for our perception while others may well be de-emphasized or completely ignored. The challenge for computer graphics is thus to maximize rendering the former and minimize the latter in order to display interactive scenes efficiently. In the talk presented at GDC 2021: "Better Computer Graphics through Understanding of Human Visual System" multiple issues related to human visual perception of static images were overviewed, notably shape, hue, shadows and illumination perception. In this talk we would like to discuss important follow-up topics related to effects of motion and animation on human perception such as human perception of the frame rate, motion recognition at different angles of the visual field, effect of color on motion recognition, optic flows and space perception.

Takeaway

Attendees will get better understanding of:

- Perception of the frame rate, flicker fusion and velocity detection
- Frame rate issues for different types of displays
- Types of eye movements, specifically smooth pursuit movement
- Motion recognition at different angles of the visual field
- Motion blur and visual system de-blurring
- Motion and visual disparity
- Motion recognition and color
- Accommodation and blur
- Space perception
- Visual masking
- Optic flows

Intended Audience

Technical Animators, Technical Artists, Animation Programmers and Graphics Programmers
