Goal of the Research

• Design and implement AR pottery modeling system
  with intuitive interface

6
System Feature

• Pottery modeling in augmented reality
• Using natural interface
• Provide methods for modeling various pottery
  design
• Provide sense of haptic
• Drawing on the pottery surface

7
Development Environment

• OpenGL
• DirectX
• ARToolkit
• WebCam
• Haptic display device
• Visual Studio .Net 2003

Storyboard

• When system started, you can choose menu
• Make pottery, Load pottery and etc
• When make pottery selected, you can choose base
  model and its clay intensity
• Models height, shape and so on
• You can make pottery in various way
• Change carving tools and hand size by selecting
  other markers
• You can view sample models and copy them
• When pottery modeling is finished, display it
• Change color, add gloss and so on

Simple Scenario

• Program started and choose make pottery
• Select cylinder base model and set intensity
  low
• Table rotating starts and select normal hand
• Move hand to make curved surface
• Stop Rotate and select carving carve knife
• Move knife to carve clay surface
• Add color or gloss using celadon enamel
• Finish modeling - make Koryo celadon
• Display and save it

Remark

• Use 3D marker
• Cube AR marker - to find hand (or carving tools)
• 3D marker is attached to haptic display device
• Pottery position is set on the rotating table
• Use marker or just set to be there
• Table rotation speed is changeable
• Use marker or button to stop, move fast or slow
• Try to use easy and simple interface
• To select menu easily
• Save it and load anytime

14
Remark

• Pottery making problem
• Assume that rotate axis has another hand to
  support pottery
• 3D marker is regarded as finger, but it can be
  extended to hand
• So, hand mode would not move finger
• You can solve this problem to use other tracking
  device
