captcha（完全自动化的公共图灵测试来区分计算机和人类）是最广泛使用的身份验证机制之一，有助于防止在线服务滥用。随着移动计算的出现，智能手机和平板电脑等移动设备已经成为人们上网的主要方式。因此，设计对移动设备友好的验证码受到越来越多的关注。尽管这种验证码通常比传统的验证码有优势，但设计一种易于在移动设备上使用的验证码方案的最佳实践是什么仍然不清楚。在本文中，我们提出了一项探索性研究，重点是通过交互式验证码开发更全面的可用性问题视图，以告知设计指导。这是通过调查代表五种不同验证码类型的七种移动友好验证码方案的可用性性能来完成的。
CAPTCHAs (Completely Automated Public Turing Test to Tell Computers and Humans Apart) are one of the most widely used authentication mechanisms that help to prevent online service abuse. With the advent of mobile computing, mobile devices such as smartphones and tablets have become the primary way people access the Internet. As a result, increasing attention has been paid to designing CAPTCHAs that are mobile friendly. Although such CAPTCHAs generally show their advantages over traditional ones, it is still unclear what the best practices are for designing a CAPTCHA scheme that is easy to use on mobile devices. In this paper, we present an exploratory study that focuses on developing a more holistic view of usability issues with interactive CAPTCHAs to inform design guidance. This is done through investigating the usability performance of seven mobile friendly CAPTCHA schemes representing five different CAPTCHA types.
