Assistive Technology (AT) allows individuals with disabilities to circumvent areas of weakness. Many AT tools have been developed for server-side environments with the assumption that students will have access to sufficiently fast internet when they need it in order to use the tools effectively. However, this is not always the case. In the current study, the impacts of client-side versus server-side applications, internet speed, and the cache on the loading time of four popular AT tools were examined. Client-side applications were expected to result in the fastest loading time, and a preloaded cache was expected to eliminate much of the disparity between high- and low-speed internet. These hypotheses were largely confirmed. There were significant differences in the time to open client-side programs compared to server-side programs with low-speed internet. Several classroom implementation strategies for server-side AT are discussed.

辅助技术 (AT) 允许残障人士绕过弱点。许多 AT 工具是为服务器端环境开发的，假设学生在需要时可以访问足够快的互联网，以便有效地使用这些工具。然而，这并非总是如此。在当前的研究中，检查了客户端与服务器端应用程序、互联网速度和缓存对四种流行 AT 工具加载时间的影响。客户端应用程序预计将导致最快的加载时间，预加载缓存预计将消除高速和低速互联网之间的大部分差异。这些假设在很大程度上得到了证实。与低速互联网的服务器端程序相比，打开客户端程序的时间存在显着差异。讨论了服务器端 AT 的几种课堂实施策略。
