2. Function of space use: Analyze readers' physical structure, psychological form, activity demand and other factors, and make the indoor environment adapt to readers' requirements through reasonable indoor space layout and furniture design.

3. Visual environment design: the color of the space interface should be harmonious and elegant, and the color of the wall is generally darker than the color of the sky. Replacing pure white with bright intermediate color can reduce readers' eye fatigue. Consider matte or dull materials as much as possible, which can avoid glare, reduce noise and create a soft and quiet reading environment for readers. Pay attention to symmetry in the use of shapes and lines, and avoid distracting readers with factors that force their eyes.
