A joint force-position measurement system for neuromotor performances assessment

This paper introduces the use of measuring both position and force in interacting with a 2D interface for neuromotor performances assessment. The system measures directly 2D position and force in interacting with images generated by an LCD. By means of those `primitive´ measurements it is possible to develop tests which estimate: reaction time, movement time, speed and accuracy, path deviation, jerk, dwelling time in target, contact force control parameters as a function of position, percentage of success in accomplishing different tasks, the root mean square errors in the previous parameters, their frequency transforms i.e. FFT or WT. About Cognitive aspects of human being it is possible to measure: Reaction Time, Attention and Memory.
