摘要

全世界每天都有数百万人使用智能手机,但标准的QWERTY键盘在盲人输入方面优化得很差。在这篇文章中,我们记录了盲人在智能手机上输入文本的各种方法,并专注于一个特殊的需求:发送短信。我们分析了两个现代的文本信息语料库,并将它们与旧的文本信息语料库以及从新闻文章、聊天室和书籍中收集的其他语料库进行了对比。我们为盲人提供了一种虚拟键盘,它被称为Ally,用于发送短信。为了评估Ally,我们对盲人参与者进行了两次用户研究。我们的第一项研究发现速度在增加,第二项研究发现一半的参与者达到了与QWERTY相当的速度,这表明它可能是一个可行的替代品。最后,我们讨论了盲人文本信息输入的未来工作。

Ally: Understanding Text Messaging to Build a Better Onscreen Keyboard for Blind People
Millions of people worldwide use smartphones every day, but the standard issue QWERTY keyboard is poorly optimized for non-sighted input. In this article, we document the variety of methods blind people use to enter text into their smartphones, and focus on one particular need: sending text messages. We analyze two modern corpora of text messages and contrast them with an older text message corpus, as well as other corpora gathered from news articles, chat rooms, and books. We present a virtual keyboard for blind people optimized for sending text messages called Ally. To evaluate Ally, we conducted two user studies with blind participants. Our first study found increasing speeds and our second study found that half of participants reached comparable speeds to QWERTY, suggesting it may be a viable replacement. We conclude with a discussion of future work for non-sighted text-entry of text messages.

期刊介绍: Computer and information technologies have re-designed the way modern society operates. Their widespread use poses both opportunities and challenges for people who experience various disabilities including age-related disabilities. That is, while there are new avenues to assist individuals with disabilities and provide tools and resources to alleviate the traditional barriers encountered by these individuals, in many cases the technology itself presents barriers to use. ACM Transactions on Accessible Computing (TACCESS) is a quarterly peer-reviewed journal that publishes refereed articles addressing issues of computing that seek to address barriers to access, either creating new solutions or providing for the more inclusive design of technology to provide access for individuals with diverse abilities. The journal provides a technical forum for disseminating innovative research that covers either applications of computing and information technologies to provide assistive systems or inclusive technologies for individuals with disabilities. Some examples are web accessibility for those with visual impairments and blindness as well as web search explorations for those with limited cognitive abilities, technologies to address stroke rehabilitation or dementia care, language support systems deaf signers or those with limited language abilities, and input systems for individuals with limited ability to control traditional mouse and keyboard systems. The journal is of particular interest to SIGACCESS members and delegates to its affiliated conference (i.e., ASSETS) as well as other international accessibility conferences. It serves as a forum for discussions and information exchange between researchers, clinicians, and educators; including rehabilitation personnel who administer assistive technologies; and policy makers concerned with equitable access to information technologies.
