Investigation of Tactile Font Presentation Variables

描述(申请人提供)本研究将探索对Elia字母、盲文字母和罗马字母的触觉识别。我们将比较读取这三个字母的速度和精度。字母将以多种字体大小显示，并具有不同的行宽、字母间距和字母高度，或者，在盲文的情况下，不同的字体大小、字母间距、点宽和字母高度。演示变量(字体大小、间距等)将进行研究，以确定改变字母表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敏感度的字母表的最佳呈现方式。 这项研究将有36名受试者。受试者将被随机分配到三个字母组中的一个。受试者将在视觉和触觉上熟悉字母表，然后通过标准测试。他们的触觉敏感度将通过一些触觉敏感度测试来测量。然后，他们将在字母表的不同呈现形式上进行测试。培训和测试的总时间约为30小时。 赠款的第二阶段将探索修改可用于商业的技术，以生产廉价的触觉文本、标签和显示器，并开发新的触觉生产手段。

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.
