Book excerpt: This book presents new research on sight translation using cutting-edge eye-tracking technology. It covers various aspects of sight translation processes of both novice and professional interpreters, such as their textual processing behaviors, problem-solving patterns and reading-speech coordination. By focusing on the features of their gaze behaviors, the book describes the interpreters' processing behaviors and categorizes them into different processing styles. As one of the first books on sight translation employing an eye-tracking technique as the research method, it offers a valuable reference guide for future eye-tracking-based translation and interpreting research.
