Effects Of Gaze Distribution On Woodworking Knowledge And Skills

This study investigates the gaze distribution of learners who watched a video about making a screw joint (a woodworking process) and explores its relationship with knowledge comprehension and skill acquisition levels. Twenty university students who had never taken a specialized class on screw joints participated in the study. They watched approximately a three-minute video on making a screw joint and completed knowledge comprehension and skill acquisition surveys based on the video content. Gaze measurements were conducted using Tobii T120, a screenbased eye-tracking device manufactured by Tobii Technology. In the line-of-sight distribution analysis, the objects appearing in the video were categorized into four areas of interest (AOI): human faces, processed areas, subtitles, and tools. Further, the viewing rates for each AOI were calculated. The rates were ranked in descending order: processed areas, human faces, subtitles, and tools. Correlation analysis showed no significant correlation between knowledge comprehension and AOI. However, significant correlations were found between skill acquisition and human faces (r = .477, p < .05), subtitles (r = -.531, p < .05), and tools (r = .510, p < .05). Furthermore, multiple regression analysis showed that human faces (? = 0.52, p < .01) and tools (? = 0.49, p < .05) positively affected skill acquisition. These results suggest that focusing on human faces and tools may enhance skill acquisition.
