Ergonomic Analysis of the Automotive Head-Up Displayed Information

Abstract

A vehicles head-up display (HUD) device enables the driver to obtain information, such as driving speed and engine conditions, to ensure safety while keeping the eyes focused on the front windshield. However, no complete and sufficient reference data are available regarding the extent of the drivers acceptability of the information displayed by such a device. Thus, this study aims to examine the drivers visual perception of the vehicular information pattern displayed by the HUD device and its influence on safe driving. The scope of this study includes the scope of the images displayed, quantity of information displayed, distribution and size of information, display brightness in different scenarios, suitable method of information display, correctness of interpretation, and so on. The researcher has built different scenarios for each item studied and analyzed the viewing effect through a questionnaire survey. A database can be built based on such data in the future. This database will contribute to the development of vehicles display systems and verification of similar future studies.
