Code for EchoTables (IKILeUS)

EchoTables is an innovative accessibility tool developed as part of the IKILeUS project at the University of Stuttgart. It is designed to improve the usability of tabular data for visually impaired users by converting structured tables into concise, auditory-friendly textual summaries. Traditional screen readers navigate tables linearly, which imposes a high cognitive load on users. EchoTables alleviates this issue by summarizing tables, facilitating quicker comprehension and more efficient information retrieval.<br>
Initially utilizing RUCAIBox (LLM), EchoTables transitioned to Mistral-7B, a more powerful open-source model, to enhance processing efficiency and scalability. The tool has been tested with widely used screen readers such as VoiceOver to ensure accessibility. EchoTables has been adapted to process diverse data sources, including lecture materials, assignments, and WikiTables, making it a valuable resource for students navigating complex datasets.

EchoTables是斯图加特大学IKILeUS项目研发的创新性辅助工具，旨在优化视障用户对表格数据的使用体验，可将结构化表格转换为简洁且听觉友好型的文本摘要。传统屏幕阅读器（screen reader）以线性方式遍历表格，会给使用者带来极高的认知负荷。EchoTables通过对表格生成摘要缓解了这一痛点，助力用户更快实现内容理解并更高效地检索信息。
该工具最初依托RUCAIBox（大语言模型，LLM）开发，后续切换至性能更强劲的开源模型Mistral-7B，以提升处理效率与可扩展性。EchoTables已与VoiceOver等主流屏幕阅读器完成适配测试，以保障其可访问性。目前，该工具已适配多种数据源，包括课程讲义、作业以及WikiTables，可为处理复杂数据集的学生提供宝贵的辅助资源。
