What are the tactile differences between WPC and natural wood in interactive sculptures?

When comparing WPC (Wood-Plastic Composite) and natural wood in interactive sculptures, the tactile differences are significant and influence both aesthetics and functionality.

1. Texture: Natural wood offers a rich, organic grain with slight imperfections, providing a warm and authentic feel. WPC, while mimicking wood, often has a smoother, more uniform surface due to its synthetic composition.

2. Temperature Sensitivity: Natural wood adjusts to ambient temperatures, feeling warmer or cooler to the touch. WPC tends to retain a neutral temperature, making it less responsive to environmental changes.

3. Durability and Feel: WPC is resistant to moisture and wear, maintaining its texture over time. Natural wood may develop patina or roughness with exposure, adding character but requiring maintenance.

4. Weight and Density: Natural wood is generally lighter and less dense than WPC, which can feel heavier and more rigid, affecting how users interact with the sculpture.

5. Sensory Feedback: Natural wood provides subtle vibrations and acoustic resonance when touched or tapped, while WPC dampens sound and feedback due to its composite nature.

These differences make each material suitable for specific artistic and interactive purposes, depending on the desired tactile experience.
