Tactual reading usually requires the coordinated use of the forearm/hand motor and tactile sensory systems. Therefore, in a series of studies of tactual reading behavior, we chose to record the text-scanning patterns of adult blind readers in an attempt to gain further insight into the nature of this process. Reading behavior for four modes of tactual reading was recorded (embossed braille one-hand, embossed braille two-hands, Optacon/letterprint, and Optacon/Inkbraille) by detecting and recording the instantaneous position of light-emitting diodes unobtrusively attached to the finger(s) or the Optacon camera. In addition to the comparative evaluation of the four sets of reading patterns, the salient features of the Optacon/letterprint patterns were quantitatively analyzed in an attempt to characterize this particular mode of reading. The text-scanning patterns of Optacon readers have not been previously reported. In general the text-scanning behavior for all modes of tactual reading seems to be similar; the only remarkable difference appears to be in the reading rates. Regarding Optacon/letterprint performance, reading rate was found to be significantly and negatively correlated with line-changing time and the number of regressions. No significant correlation was evident between rate and regression magnitude.
触觉阅读通常需要前臂/手部运动和触觉感觉系统的协同使用。因此，在一系列触觉阅读行为研究中，我们选择记录成年盲人读者的文本扫描模式，以便进一步深入了解这一过程的本质。通过检测并记录不显眼地附着在手指或Optacon相机上的发光二极管的瞬时位置，记录了四种触觉阅读模式的阅读行为（凸字盲文单手阅读、凸字盲文双手阅读、Optacon/字母印刷阅读和Optacon/油墨盲文阅读）。除了对四组阅读模式进行比较评估外，还对Optacon/字母印刷模式的显著特征进行了定量分析, 以便描述这种特定的阅读模式。此前尚未报道过Optacon读者的文本扫描模式。一般来说，所有触觉阅读模式的文本扫描行为似乎都相似；唯一显著的差异似乎在于阅读速度。关于Optacon/字母印刷的表现，发现阅读速度与换行时间和回读次数呈显著负相关。速度与回读幅度之间没有明显的相关性。
