2. Canine Acupuncture Background Holistic Approach: Traditional Chinese Medicine Concepts Qi = Life Force Meridians = Pathways of Qi Benefits Arthritis Allergies Neck/Back Pain Paralysis Resuscitation ~ 75 Acupuncture Points

3. Certification Integral Part of Veterinary Medicine License Required Drawbacks Cost Realism Reusability Ethics Canine Acupuncture Training SimPooch Solution: A Virtual Canine Acupuncture Simulator, SimPooch!

4. 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.

5. 1.Design Haptic model approximation of canine skin 2.Incorporate Accurate Grading Criteria 3.Expand User Interface Current Work

6. 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

7. Haptics PythonH3D APIPhantom What is Haptics? (Definition) How do we sense the world? Benefits of using haptics for training Python with H3D API Omni Phantom Device

9. Grading: Voronoi Algorithm Grading Outcomes Student Touches Cell Occupied By Teacher Point Multiple Touches in Cell Occupied By Teacher Point Absence of Touch in Cell Occupied by Teacher Point Student Touches On Border Between Cells Student Point Associated with Teacher Point. Pass. Closer Student Point Associated with Teacher Point. Pass. Student Point Not Associated. Miss.
