Analysis of the Human-Computer Interaction on the Example of Image-based CAPTCHA by Association Rule Mining
This is an incremental study on CAPTCHA usability for web security and user experience design.
The paper analyzed human-computer interaction by measuring response times of 100 Internet users solving four types of image-based CAPTCHAs, revealing insights into user psychological states based on age, education, and experience.
The paper analyzes the interaction between humans and computers in terms of response time in solving the image-based CAPTCHA. In particular, the analysis focuses on the attitude of the different Internet users in easily solving four different types of image-based CAPTCHAs which include facial expressions like: animated character, old woman, surprised face, worried face. To pursue this goal, an experiment is realized involving 100 Internet users in solving the four types of CAPTCHAs, differentiated by age, Internet experience, and education level. The response times are collected for each user. Then, association rules are extracted from user data, for evaluating the dependence of the response time in solving the CAPTCHA from age, education level and experience in internet usage by statistical analysis. The results implicitly capture the users' psychological states showing in what states the users are more sensible. It reveals to be a novelty and a meaningful analysis in the state-of-the-art.
