Canine Acupuncture BackgroundHolistic Approach: Traditional Chinese Medicine
ConceptsQi = Life ForceMeridians = Pathways of Qi
Benefits•Arthritis•Allergies•Neck/Back Pain•Paralysis•Resuscitation
~ 75 Acupuncture Points
Certification• Integral Part of Veterinary Medicine• License Required
Drawbacks• Cost• Realism• Reusability• Ethics
Canine Acupuncture Training
Solution: A Virtual Canine Acupuncture Simulator, SimPooch!
Project Status
•Teams in AY06 developed the physical system
-Base Unit Design
•Teams in AY07 developed the virtual shell
-MRI & CT Scans
Our Goal: To Make Training Virtually Painless.
1. Design Haptic model approximation of canine skin
2. Incorporate Accurate Grading Criteria
3. Expand User Interface
Current Work
The Feel of Acupuncture
•Distinct feel of 3 layers•Minimal deformation •Resistive force to remove needle•Variations of feeling in different areas•Feeling changes over time
Haptics
Python H3D API Phantom
What is Haptics? (Definition)
How do we sense the world?
Benefits of using haptics for training
Python with H3D API
Omni Phantom Device
Haptic System Model
Grading: Voronoi Algorithm
Grading OutcomesStudent Touches Cell Occupied By Teacher
Point
Multiple Touches in Cell Occupied By
