- To compare the effectiveness of planning movements using joint angles versus endpoint Cartesian coordinates.
Main Methods:
- Kinematic modeling of human arm trajectories.
- Matching modeled trajectories to actual human movements.
- Analysis of linear and staggered interpolation strategies for planning variables.
Main Results:
- Distinguishing between joint angle and endpoint Cartesian coordinate planning is dependent on the workspace region.
- The motor control system exhibits distinct coordination strategies based on movement context.
Conclusions:
- The brain utilizes different planning variables for motor control depending on the task and environment.
- This research provides insights into the adaptability and complexity of human movement planning.
