Abstract
In a previous study, interactive 3D CAPTCHA was proposed as an alternative method to assist users to pass the CAPTCHA tests easily and pleasurably. In addition, usability issues were reported in the same study. This current study, introduces several design changes of interactive 3D CAPTCHA to overcome the usability issues. The new design was evaluated by testing the effects of parameters on KLM execution time within experimental studies. Test results showed that the most effective methods are using arrow keys, using underline characters, using high contrast between foreground and background of cube faces, excluding case sensitivity for input validation and removal of question marks from input boxes. The new design reduced KLM execution time from 45.9 seconds to 16.2 seconds.
期刊介绍：
The ICIC Express Letters, Part B: Applications (abbreviated as ICIC-ELB) is a peer-reviewed English language journal of research and surveys on Innovative Computing, Information and Control, and is published by ICIC International monthly. The primary aim of the ICIC-ELB is to publish timely quality short papers (generally no more than 8 printing pages) with emphasis on applications of established or new developed novel techniques, approaches and methodologies of computing systems, intelligent systems, information processing, and automation and control systems.
