A tactile display device that can present tangible relief graphics for visually impaired persons has been developed. The tactile surface consists of a 64 x 64 arrangement of tactorpins with 3 mm interspacing. The tactor-pins are aligned in a hexagonal, rather than a square formation, to assure smooth depiction. The matrix has a total area of 200 mm x 170 mm. Each pin can be raised in 0.1 mm steps to a maximum height of 10 mm. Users can get certain information by touching the pins raised at varying heights with fingers and/or palms. Laboratory assessment of the device with six blind subjects showed its ability to transmit various kinds of information.
一种能够为视障人士呈现可触摸浮雕图形的触觉显示设备已被研发出来。触觉表面由64×64排列的触觉针组成，针间距为3毫米。触觉针呈六边形排列，而非正方形排列，以确保图形描绘平滑。该矩阵的总面积为200毫米×170毫米。每根针可以以0.1毫米的步长升高，最大高度为10毫米。用户通过用手指和/或手掌触摸不同高度凸起的针来获取特定信息。对6名盲人受试者进行的该设备实验室评估表明其能够传输各类信息。
