Most conventional computer hardware systems have been inadequately designed for the functional comfort and efficient usage by human operators. The effects of excyclotorsion, inadequate depression-of-gaze, excessive hand-wrist pronation, and ulnar abduction are discussed. The neurology of ocular movements, synkinesis, saccades, pursuits, and orthopedic hand-wrist biomechanics are reviewed. The interrelationships of these ocular and orthopedic phenomena have been synthesized into a comprehensive hypothesis, in an effort to create a computer configuration which permits a greater integration of the keyboard (tool-usage) with the screen-visualization (product-of-tool-usage), and improves visual feedback.
大多数传统计算机硬件系统在设计上未能充分考虑人类操作员的功能舒适性和高效使用性。文中讨论了外旋转斜视、凝视下降不足、手腕过度旋前和尺侧外展的影响。回顾了眼球运动、联带运动、扫视、追踪的神经学以及手部和手腕的矫形生物力学。这些眼部和矫形现象之间的相互关系已被综合成一个全面的假设，旨在创建一种计算机配置，使键盘（工具使用）与屏幕可视化（工具使用的产物）能更好地整合，并改善视觉反馈。
