DESCRIPTION (provided by applicant) This research will explore the tactile recognition of the ELIA, Braille and Roman alphabets. The speed and accuracy with which the three alphabets are read will be compared. The alphabets will be presented at a number of font sizes and with varying line widths, letter spacing and letter raises, or, in the case of Braille, varying font sizes, letter spacing, dot widths, and letter raises. Presentation variables (font size, spacing, etc.) will be studied to ascertain whether varying them affects recognition speed and accuracy and whether there are optimal presentations of the alphabets for different tactile sensitivities. There will be 36 subjects in the study. The subjects will be randomly assigned to one of three alphabet groups. Subjects will familiarize themselves with the alphabets visually and tactilely and then pass criterion tests. Their tactile sensitivities will be measured with a number of tactile acuity tests. They will then be tested on varied presentations of the alphabets. Total training and testing time will be approximately 30 hours. Phase II of the grant will explore the modification of commercially available technology that can produce inexpensive tactile texts, labels and displays, and the development of new tactile production means.

描述（由申请人提供） 本研究将探讨 ELIA、盲文和罗马字母的触觉识别。将比较这三个字母的阅读速度和准确性。字母表将以多种字体大小和不同的线宽、字母间距和字母凸起呈现，或者，在盲文的情况下，具有不同的字体大小、字母间距、点宽度和字母凸起。将研究呈现变量（字体大小、间距等），以确定改变它们是否会影响识别速度和准确性，以及是否存在针对不同触觉灵敏度的字母表的最佳呈现。 这项研究将有 36 个科目。受试者将被随机分配到三个字母组之一。受试者将在视觉和触觉上熟悉字母表，然后通过标准测试。他们的触觉敏感性将通过一系列触觉敏锐度测试来测量。然后他们将接受不同字母表的测试。培训和测试总时间约为 30 小时。 该赠款的第二阶段将探索对可生产廉价触觉文本、标签和显示器的商用技术进行修改，以及开发新的触觉生产手段。
