为发展中国家的农村用户设计信通技术系统是困难的，原因多种多样，从基础设施问题到用户情况和能力的巨大差异。发展中地区的口语可能存在巨大差异，用户往往识字率低或不识字，与数字技术互动的经验很少。研究人员探索了使用无文本图形界面以及基于语音的应用程序来克服与语言和识字有关的一些问题。虽然这些方法各有优缺点，但它们在一起使用时可以相互补充。在这项工作中，我们提出了VideoKheti，一个移动的系统，使用语音，图形和触摸互动低识字的农民在印度农村。VideoKheti帮助农民查找和观看以他们自己的语言和方言制作的农业推广视频。在本文中，我们详细介绍了VideoKheti的设计和开发，并报告了一项实地研究，20名印度农村农民被要求根据一个场景找到视频。结果表明，农民可以使用VideoKheti，但他们的成功仍然在很大程度上取决于他们的教育水平。虽然参与者对使用该系统充满热情，但多模式界面并没有克服低文化用户的许多障碍。
Designing ICT systems for rural users in the developing world is difficult for a variety of reasons ranging from problems with infrastructure to wide differences in user contexts and capabilities. Developing regions may include huge variability in spoken languages, and users are often low- or non-literate, with very little experience interacting with digital technologies. Researchers have explored the use of text-free graphical interfaces as well as speech-based applications to overcome some of the issues related to language and literacy. While there are benefits and drawbacks to each of these approaches, they can be complementary when used together. In this work, we present VideoKheti, a mobile system using speech, graphics, and touch interaction for low-literate farmers in rural India. VideoKheti helps farmers to find and watch agricultural extension videos in their own language and dialect. In this paper, we detail the design and development of VideoKheti and report on a field study with 20 farmers in rural India who were asked to find videos based on a scenario. The results show that farmers could use VideoKheti, but their success still greatly depended on their education level. While participants were enthusiastic about using the system, the multimodal interface did not overcome many obstacles for low-literate users.
