Figure Lengend Snippet: ( a ) Twenty-one hand-knuckle landmarks obtained from MediaPipe hand landmark model, and their corresponding anatomical areas are illustrated on the left side image. Each dot represents the joints, and line represents the Euclidean distance from each joint. Corresponding labels in the illustration are - 1. Wrist, 2. CMC-T, 3. MCP-T, 4. IP-T, 5. TIP-T, 6. MCP-I, 7. PIP-I, 8. DIP-I, 9. TIP-I, 10. MCP-M, 11. PIP-M, 12. DIP-M, 13. TIP-M, 14. MCP-R, 15. PIP-R, 16. DIP-R, 17. TIP-R, 18. MCP-P, 19. PIP-P, 20. DIP-P, 21. TIP-P. The right-side image represents the virtual hand model with 14 joints, labeled as 1. MCP-T, 2. IP-T, 3. MCP-I, 4. PIP-I, 5. DIP-I, 6. MCP-M, 7. PIP-M, 8. DIP-M, 9. MCP-R, 10. PIP-R, 11. DIP-R, 12. MCP-P, 13. PIP-P, 14. DIP-P where T-Thumb, I-Index, M-Middle, R-Ring and P-Pinky fingers. ( b ) The first five hand gestures recognized through MediaPipe from mudras and natural grasps dataset is illustrated here. Their corresponding virtual hand model obtained by applying Gaussian function to 14 joint angular velocities is shown below them. Here M – Mudras, VM – Virtual Mudras, N – Natural Grasps, VN – Virtual Natural Grasps. The numbers indicates the corresponding hand gestures in Table . Virtual 3D Hand Model was developed using V-Realm Builder, MATLAB Simulink 3D Animation , Version R2023a .
