最近的研究表明，让远程人员回答盲人用户的视觉问题是有潜力的。从表面上看，社交网站（sns）提供了一个有吸引力的免费人力资源，可以为用户提供个性化的答案。在本文中，我们探讨了盲人用户向他们的社交网络提出视觉问题的潜力。我们通过对191名盲人进行调查，首次正式研究了盲人如何使用社交网站。我们还通过使用VizWiz Social（一个拥有超过5000名用户的iPhone应用程序，它允许盲人用户向人群或朋友提问）的问题日志分析，探索盲人用户是否认为社交网站是一个合适的问答场所。然后，我们报告了23名盲人VizWiz Social用户的现场实验结果，该实验探讨了在非社会资源存在货币成本的情况下，在VizWiz Social上提问的结果。我们发现，盲人在社交网站上有大量的用户，但他们并不认为这是一个合适的提问场所，因为他们认为社交成本很高。
Recent work has shown the potential of having remote humans answer visual questions that blind users have. On the surface social networking sites (SNSs) offer an attractive free source of human-powered answers that can be personalized to the user. In this paper, we explore the potential of blind users asking visual questions to their social networks. We present the first formal study of how blind people use social networking sites via a survey of 191 blind adults. We also explore whether blind users find SNSs an appropriate venue for Q&A through a log analysis of questions asked using VizWiz Social, an iPhone app with over 5,000 users, which lets blind users ask questions to either the crowd or friends. We then report findings of a field experiment with 23 blind VizWiz Social users, which explored question asking on VizWiz Social in the presence of monetary costs for non-social sources. We find that blind people have a large presence on social networking sites, but do not see them as an appropriate venue for asking questions due to high perceived social costs.
