An Object Model and Interaction Method for a Simulated Experience of Pottery on a Potter's Wheel

Area of Science:

• Computer Graphics
• Human-Computer Interaction
• Virtual Reality

Background:

• Simulating physical crafts like pottery in virtual environments presents unique challenges.
• Developing intuitive interaction methods is crucial for realistic digital experiences.

Purpose of the Study:

• To introduce a new object model and interaction method for simulated pottery on a virtual potter's wheel.
• To enable users to create diverse bowl shapes through a user-friendly interface.

Main Methods:

• A layered cylinder model was developed for 3D pottery objects.
• Three deformation functions were defined for shaping external surfaces, inner contours, and height.
• A simplified hand-finger interaction method was implemented within a three-dimensional aerial image interface (3DAII).

Main Results:

• The proposed layered cylinder model and interaction method were successfully implemented in the 3DAII system.
• Preliminary evaluations confirmed the system's operability and the effectiveness of the interaction methods.
• Participants could create cylindrical, dome-shaped, and flat-type bowls within 30 minutes.

Conclusions:

• The developed system provides a viable and engaging simulated experience for pottery creation.
• The combination of the layered cylinder model and intuitive interaction facilitates the creation of various bowl shapes.
• The system demonstrates potential for use in virtual reality-based craft education and entertainment.
