  • Title: The computer user syndrome.
    Author: Grant AH.
    Journal: J Am Optom Assoc; 1987 Nov; 58(11):892-901. PubMed ID: 3693780.
    Abstract:
    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.
