Abstract

This research investigates the applicability of F. Davis' Technology Acceptance Model (TAM) to OCR-based CAPTCHAs involved in a free e-mail accounts registration process. The results provide preliminary evidence that the model may be a useful tool for research focused on acceptance of CAPTCHAs. The results are especially interesting when it comes to the concept of perceived usefulness and its direct relationship to the concept of attitude toward use. This relation indicates a new area of research for CAPTCHA developers interested in improving usability and accessibility of these systems.
