Using Statistical Methods to Comparatively Analyze the Visual Characteristics of Flattened Bamboo Boards in Different...

Area of Science:

• Materials Science
• Wood Science
• Color Science

Background:

• Consumer preference for flattened bamboo boards is influenced by visual effects.
• The visual characteristics of flattened bamboo boards from different culm positions remain largely unquantified.
• Understanding these properties is crucial for material application and design.

Purpose of the Study:

• To clarify the visual, physical, and psychological effects of flattened bamboo boards from different bamboo culm positions.
• To establish quantitative relationships between physical measurements and perceived visual qualities.
• To provide a theoretical basis for furniture design and material standardization.

Main Methods:

• Quantitative color (CIELAB L*a*b*) and glossiness (G) measurements were performed on flattened bamboo boards from different culm parts (outer layer, outer, inner).
• Quantitative semantic differential and statistical methods were employed for visual psychological assessments.
• Predictive models for visual psychological quantities were developed.

Main Results:

• Lightness (L*) and blue-yellow index (b*) decreased from base to top of bamboo culms, while green-red index (a*) increased.
• Outer bamboo layer showed lower L* values and higher glossiness compared to outer and inner parts.
• Psychological assessments revealed distinct perceptions: outer layer as 'nature-practical', inner as 'artificial-practical', and outer as 'artificial-decorative'.

Conclusions:

• Distinct visual and psychological properties exist across different sections of flattened bamboo boards.
• Quantitative data provides a basis for selecting bamboo materials for specific design applications.
• This research supports informed decision-making in furniture design and standardized material use.
