面向盲人阅读的触觉交互服务框架构建与应用研究

目的/意义]在全民阅读的推广过程中,满足视障人群的阅读需求、保证其阅读权益具备重要的社会意义。针对网络时代人们的阅读习惯和兴趣从传统的文本向文字、图像和图形等多元化进行拓展的发展趋势,通过对盲人阅读和力触觉自然交互的相关问题进行探讨,提出一种面向盲人阅读的触觉交互服务框架。方法/过程]盲人阅读的触觉交互服务框架在对触觉认知规律、感知特性进行分析的基础上,重点阐述触觉对象建构、触觉智能交互和触觉信息呈现等盲人阅读中的关键技术。引入典型的笔式触觉再现设备构建面向盲人阅读的触觉交互服务的实验平台,分阶段对信息资源触觉阅读的有效性和不同层级信息资源的可理解性进行实验。结果/结论]实验结果表明,该平台在信息资源的盲人阅读方面拥有良好的沉浸感、交互性和可行性;同时验证不同层级的信息资源在触觉阅读和理解的难度上存在着差异,而干预训练的合理引入可有效提升操作者对信息资源的感知和识别能力。

Construction and Usage of Haptic Interaction Services for Blind Reading

Purpose/significance] In the promotion process of the civil reading, it is of great social significance to meet the reading needs of visually impaired people and ensure their reading rights. With the advent of the Internet era, people's reading habits and interests begin to expand from traditional texts to diversified forms, such as words, images and graphics.Method/process] In this paper, the related problems of blind reading are discussed and a novel tactile interaction framework for blind reading is presented. The tactile cognition and perceived characteristics is firstly analyzed and then a set of the key issues about blind reading are elucidated. By introducing a typical force feedback device to build a tactile interaction system, the experiment is comprised of two stages:the effectiveness of tactile reading and the comprehensibility of information resources at different levels.Result/conclusion] Experimental results showed that the tactile interaction system has excellent performances in immersion, interactivity and feasibility. It is proved that there are differences in the difficulty of tactile reading and comprehensibility of information resources at different levels, and the rational introduction of cognitive training mechanism can effectively improve the operator's perception and recognition ability.
