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）：本研究培训项目的目的是通过心理物理学实验确定由自动系统（“TMAP”）生成的触觉街道地图的最佳布局参数，以帮助盲人和视障旅行者。TMAP（触觉地图自动化生产）被申请人设想为向个人提供任何感兴趣区域的低成本、按需触觉地图的手段。它将使用一个网络接口来利用现有的计算机化地图数据库，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地点为中心的当地地图，以便立即在用户的盲文阅读器上显示（或通过现有的盲文压印服务）。为了使这样的系统有效，需要研究一些布局和呈现参数，以确定这种类型的街道地图的最佳触觉密度、街道线厚度和标签放置。本项目的目标是进行必要的实验，以优化这些参数。
