Study summary
Facial aesthetics has always been a complex and subjective concept. The overall facial harmony, along with lip protrusion, which is often a focus for orthodontists, requires evaluation from multiple perspectives. The viewing angle also influences the assessment of facial aesthetics, particularly the judgment of lip protrusion. This study aims to explore the differences in facial fixation patterns and aesthetic evaluations among different populations at specific viewing angles by using digital models to simulate various perspectives.

Primary outcome measure(s)
Total fixation duration of area of interest — The duration of the experiment for each participant does not exceed 10 minutes. A random selection of 10 participants will immediately undergo a repeat experiment after the first round to verify the reliability of the participants. The facial images used as stimulus materials are divided into several regions, with the fixation duration in each area of interest serving as the primary measurement. Changes in fixation duration represent a shift in the focus of attention.
