Analysis on the visual recognition effect of Tibetan-Chinese bilingual guide signs
摘要
Abstract
The influence of Tibetan characters on the visual recognition effects of Tibetan-Chinese bilingual guide signs based on drivers' visual characteristics was studied. Four versions of Tibetan-Chinese bilingual guide signs with different heights and aspect ratios of Tibetan characters were designed, and corresponding road simulation models were established. 10 Tibetan drivers and 10 Han drivers were selected to conduct driving simulation experiments using a driving simulator and eye tracker. The resultant data of the participant's pupil diameter and the visual recognition duration obtained from the eye tracker system were analyzed by analysis of variance. Combining results from the statistical analysis of driving simulator data and the questionnaire results on the visual recognition experience, it can be concluded that for Tibetan drivers, when the height of Tibetan characters was 2/3 of the height of Chinese characters, the visual recognition effect of the signs was better than that of 1/3 and 1/2 of the height of Chinese characters, indicating that increasing the height of Tibetan characters was conducive to improving the visual recognition effect of guide signs. The aspect ratio form of Tibetan had no significant effect on the level of difficulty encountered in drivers' visual recognition, but it would affect the aesthetics of the bilingual guide signs. The recommended character height in Tibetan should be increased to improve the visual recognition process for Tibetan drivers.关键词
