本研究的目的是评估不同类型的计算机指向设备和位置的姿势和肌肉活动的手和arm.A重复测量实验室研究与12名成年人（6名女性，6名男性）进行的影响。参与者使用传统鼠标、轨迹球、独立触摸板和滚轮鼠标完成两项鼠标密集型任务。运动分析系统和肌电图系统监测右上肢姿势和肌肉活动，分别。滚轮鼠标条件与更中性的手姿势（较低的指尖间伸展和更大的手指屈曲）沿着显著较低的前臂伸肌活动相关。与其他类型的定点设备相比，位于中央的触摸板和滚轮鼠标与更中性的肩部姿势、减少的尺骨偏斜和更低的前臂伸肌活动相关。用户报告使用轨迹球和触摸板最困难。滚轮鼠标并不比其他任何设备更难使用。这些结果表明，计算机定点设备的设计和位置引起显着不同的姿势和前臂肌肉活动在使用过程中，特别是手的姿势指标。
The goal of this study was to evaluate the effect of different types of computer pointing devices and placements on posture and muscle activity of the hand and arm. A repeated measures laboratory study with 12 adults (6 females, 6 males) was conducted. Participants completed two mouse-intensive tasks while using a conventional mouse, a trackball, a stand-alone touchpad, and a rollermouse. A motion analysis system and an electromyography system monitored right upper extremity postures and muscle activity, respectively. The rollermouse condition was associated with a more neutral hand posture (lower inter-fingertip spread and greater finger flexion) along with significantly lower forearm extensor muscle activity. The touchpad and rollermouse, which were centrally located, were associated with significantly more neutral shoulder postures, reduced ulnar deviation, and lower forearm extensor muscle activities than other types of pointing devices. Users reported the most difficulty using the trackball and touchpad. Rollermouse was not more difficult to use than any other devices. These results show that computer pointing device design and location elicit significantly different postures and forearm muscle activities during use, especially for the hand posture metrics.
