Abstract

ABSTRACTTechnologies have advanced quickly over the years, making them increasingly diverse every day. Along with this technological advancement, the number of elderly people have grown exponentially in recent years and tend to increase even more. This part of the population is having a greater interest in using these new technologies due to the ease generated. For this reason, they must be accessible to users of all ages. This research aims to evaluate the perception when using the CAPTCHA security mechanism on websites, focusing on elderly users. The main results of the study were the preference for image CAPTCHAs, considering them easier than textual ones. It was found that, in addition to age, factors such as vision problems, education and average daily Internet use influenced the resolution of CAPTCHAs. In addition, the volunteers were observed to feel at ease when resolving this security mechanism.
老年用户与验证码交互感知的可用性研究
摘要近年来,科技飞速发展,使其日益多样化。随着这种技术的进步,老年人的数量近年来呈指数级增长,并有进一步增长的趋势。由于产生的便利性,这部分人口对使用这些新技术有更大的兴趣。因此,它们必须适合所有年龄的用户。本研究旨在评估在网站上使用CAPTCHA安全机制时的感知,重点关注老年用户。研究的主要结果是对图像验证码的偏好,认为它们比文本验证码更容易。研究发现,除年龄外,视力问题、教育程度和平均日常互联网使用等因素也会影响验证码的分辨率。此外,研究人员还观察到,志愿者在解决这一安全机制时感到轻松自在。
