The first goal of this study was to develop a 2 degree of freedom (DOF) upper limb controller utilizing shoulder elevation/depression and protraction/retraction. Its primary purpose is to control powered prosthetic shoulder joints being incorporated into a new generation of prosthetic arms for shoulder disarticulation and very high transhumeral amputees. More generally, however, such a controller can be applied to simultaneously control any 2 DOF's under a direct, proportional control scheme. There is no generally accepted method to objectively and quantitatively evaluate prosthesis and prosthesis control performance, and the second goal of this study was to develop one based on Fitts Law. The evaluation protocol has quite general applicability as well, and can be used to compare different reaching/ pointing devices, or to compare variations in the design or operation of a particular device.
本研究的首要目标是开发一种利用肩部抬高/降低以及前伸/后缩的两自由度（DOF）上肢控制器。其主要目的是控制动力假肢肩关节，该关节将被整合到新一代用于肩关节离断和极高位肱骨截肢患者的假肢手臂中。然而，更普遍地说，这样一种控制器可以应用于在直接比例控制方案下同时控制任何两个自由度。目前尚无客观定量评估假肢及假肢控制性能的普遍接受的方法，本研究的第二个目标是基于菲茨定律开发一种评估方法。该评估方案也具有相当广泛的适用性，可用于比较不同的伸手/指向装置，或比较特定装置在设计或操作上的差异。
