Human goal directed arm movements are studied by making use of mathematical models. Such models that describe movements as outputs on input step tracking tasks, consist of a linear differential equation. The approach is based on control engineering concepts and finds its origin in the field of man-machine systems. Starting from two existing models for continuous tracking tasks, five related models for step tracking are investigated. Two types of experiments have been executed with a manipulator having the characteristics of a lightly damped mass and a controlled system characterised by a simple gain factor. It was found that a simple feedback model with an additional delay time outside the control loop was very satisfactory for the four subjects engaged in the experiments, for forward and backward movements and for movements with continuous visual information as well as for movements with interrupted visual information. An extension of the model with a feedforward element was found to be rather irrelevant for the experimental conditions applied. |
