Bodytalk V2 - The Extended Skeleton Edition

BodyTalk V2: The Extended Skeleton Edition

• Postural alignment and static balance: center-of-mass (CoM) position, sway area, segment angular offsets.
• Gait analysis: spatiotemporal metrics (step length, cadence), joint kinematics, ground reaction force symmetry, energetic cost proxies.
• Functional tasks: sit-to-stand, reach-and-grasp, loaded lifts — task-specific kinematic and kinetic metrics.
• Somatic state indices: muscular co-contraction indices, fascial stiffness surrogates, autonomic correlates (HRV during task).

, allowing users to build custom body shapes or use presets like "Swimmer". bodytalk v2 - the extended skeleton edition

• Inverse kinematics optimization (pseudocode):

  minimize_x  Σ_w ||marker_obs - H(x)||^2 + λ||W·(x - x_prior)||^2
  subject to joint_limits
  

• IMU–pose fusion (EKF) skeleton:

  predict: x_k+1 = f(x_k, u_k) + process_noise
  update: z_k = h(x_k) + measurement_noise
