ABSTRACT

Visually impaired people use tactile maps that can be read by the sense of touch or, to a limited extent, with their eyes. This article concerns the methods of assessing tactile maps in terms of their information value. In the research, methods used to assess traditional maps have been adopted to assess tactile maps. Tactile elements of two maps – one developed with the use of traditional methods and the second developed with the use of 3D printing – have been compared. Structural measures of information as well as the information efficiency coefficient of each map have been determined to assess whether new cartographic symbols proposed on a multi-level 3D printed map can increase its information value.

摘要

视力受损的人使用触觉地图，可以通过触觉或在有限的范围内用眼睛阅读。本文涉及根据信息价值评估触觉地图的方法。在研究中，用于评估传统地图的方法已被用于评估触觉地图。对两张地图的触觉元素——一张使用传统方法开发，另一张使用 3D 打印开发——进行了比较。已确定信息的结构度量以及每张地图的信息效率系数，以评估在多级 3D 打印地图上提出的新制图符号是否可以增加其信息价值。
