DESCRIPTION (provided by applicant): The aim of this research training project is to determine, through psychophysical experiments, optimal layout parameters for tactile street maps to be generated by an automated system ("TMAP") to assist blind and visually impaired travelers. TMAP (Tactile Maps Automated Production) was conceived by the applicant as a means of providing low-cost, on-demand tactile maps of any area of interest to an individual. It would use a web interface to harness existing computerized map databases such as that provided by the US Census Bureau, and synthesize local maps centered on any location specified by the user, for immediate printout on the user's Braille embosser (or by existing Braille embossing services). For such a system to be effective, research is needed into some of the layout and presentation parameters, to determine optimal tactile density, street line thicknesses, and label placement for this type of street map. The goal of the present project will be to conduct the necessary experiments to optimize these parameters.

描述（由申请人提供）：该研究培训项目的目的是通过心理物理实验确定由自动化系统（“ TMAP”）生成的触觉街道图的最佳布局参数，以帮助盲人和视觉上的旅行者。申请人认为TMAP（触觉地图自动生产）是提供个人感兴趣领域的低成本，按需触觉图的一种手段。它将使用Web界面来利用现有的计算机地图数据库，例如美国人口普查局提供的数据库，并合成以用户指定的任何位置为中心的本地地图，以立即在用户的盲文浮雕上打印出来（或通过现有的Brailes浮雕服务）。为了使这样的系统有效，需要在某些布局和演示参数中进行研究，以确定此类街道图的最佳触觉密度，街道线厚度和标签位置。本项目的目的是进行必要的实验以优化这些参数。
