本研究考察了打字广度以及在打字时看字时间与打字时间的协调性。在实验1中，打字员抄写文本段落，同时测量他们的眼球运动。在每次眼睛注视期间确定观看位置，并用于控制可用视觉信息的量。观看限制减少字间扫视的大小时，少于7个字符空间的文本是可见的固定的权利和增加键间时间时，少于3个字符空间的文本是可见的。手眼跨度为2.8个字符空间。实验2揭示了增加打字时间和单词查看时间的生物力学打字难度增加，词频下降。这些发现与眼手协调模型一致，该模型假设眼手协调涉及中枢和外周过程。
Typing span and coordination of word viewing times with word typing times in copytyping were examined. In Experiment 1, typists copied passages of text while their eye movements were measured. Viewing location was determined during each eye fixation and was used to control the amount of usable visual information. Viewing constraints decreased interword saccade size when fewer than 7 character spaces of text were visible to the right of fixation and increased interkeypress times when fewer than 3 character spaces of text were visible. The eye-hand span amounted to 2.8 character spaces. Experiment 2 revealed increases in word typing times and word viewing times as biomechanic typing difficulty increased and word frequency decreased. These findings are consistent with a model of eye-hand coordination that postulates that eye-hand coordination involves central and peripheral processes.
