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。将比较这三种字母的阅读速度和准确性。字母将以多种字体大小显示，并具有不同的行宽、字母间距和字母凸起，或者，就盲文而言，具有不同的字体大小、字母间距、点宽和字母凸起。显示变量（字体大小、间距等）将进行研究，以确定改变它们是否会影响识别速度和准确性，以及是否有不同触觉敏感度的字母的最佳呈现。 本研究将纳入36例受试者。受试者将被随机分配到三个字母组之一。受试者将在视觉和听觉上熟悉字母表，然后通过标准测试。他们的触觉灵敏度将通过一些触觉敏锐度测试来测量。然后，他们将在不同的字母表上进行测试。培训和测试时间约为30小时。 第二阶段的拨款将用于研究改良市面上现有的技术，以生产廉价的触觉文本、标签和显示，以及开发新的触觉生产方法。
