相同实验条件下的自由手运动会导致运动轨迹略有不同。为了将这种性能变化与到达区域的某些位置或工作过程的某些元素相关联，开发了一种新方法来分析空间中的连续手部运动。在执行复杂定位任务期间，针对到达区域中的六个位置以及工作时间，研究了用于描述性能变异性的六个参数。计算出的参数因位置不同而明显不同，并且在工作期间变化显着。基于这些结果，可以确定定位过程在哪个位置产生最小的努力。结果是根据肌电图测量进行评估的，并强调建议，应优先考虑受试者前面不太靠近身体的小触及区域，以实现积极的表现。
Free hand-movements under identical experimental conditions lead to slightly different movement traces. In order to correlate this performance variability with certain locations of the reaching area or certain elements of the working process a new method has been developed to analyse continuous hand-movements in space. Six parameters for the description of the performance variability have been investigated during the execution of a complex positioning task with respect to six locations in the reaching area and with respect to the time at work. The computed parameters differ clearly from location to location and change significantly during the working period. On the basis of these results it is possible to determine at which location the positioning procedure leads to minimal effort. The results have been evaluated on the basis of EMG-measurements and emphasize the recommendation that the small reaching area in front of the subject not too close to the body should be favoured for the performance of a posit...
