The influence of visual angle on Mongolian character recognition

In recent years, there have been many achievements in Mongolian studies. Scholars have carried out eye movement characteristics analysis and research from the aspects of reading gaze position effect, combined with the effect of high and low frequency words on gaze position and other aspects of Mongolian cognitive research. However, there is no systematic study on the influence of visual angle on Mongolian character recognition. This research addresses the above-mentioned problems, taking visual angle as the independent variable and reaction time as the dependent variable, selecting the commonly used Mongolian vowel consonants and divide them into seven visual angles of 2°, 4°, 7°, 10°, 13°, 16°, and 19°. Discussing the impact of the reaction time on the visual angle and the best recognition visual angle. The research showed that at 19°, the reaction time was the shortest and the recognition effect was better. Therefore, the best visual angle of Mongolian language could be identified in order to improve the efficiency of recognition, enrich the research in the field of Mongolian language study, and promote the development of Mongolian language research.
