碩士 === 實踐大學 === 工業產品設計學系碩士在職專班 === 104 === The purpose of this research is to explore optimal interface design for applications in a car navigation head-up display (HUD) shown on mobile devices, to help drivers make better decisions via optimized setting of interface parameters. The research procedure includes three stages. The first stage is pre-experiment I, using a questionnaire to collect data about drivers’ perceptions and experiences in using a HUD for navigation, and drivers’ needs for information on a HUD, in order to analyze current navigation information and expectations for apps in a HUD. The second stage is pre-experiment II, in which an analysis of the survey results showed that text is the important factor, so we made text samples, based on Taguchi Methods of Robust Design orthogonal array, then we continued to finish the primary and secondary experiments along with variance analysis. The third stage is main experiment, in which we made interface samples of a navigation HUD, based on Taguchi Methods of Robust Design orthogonal array, then we continued to finish the experiment along with variance analysis. To verify the experiments, the subject drivers were requested to drive cars in a real environment on a planned route to verify the interface design for the navigation HUD apps. The results showed that the same design can be used both in daytime and nighttime as follows: optimal design for next turn of the road distance is numeric value plus distance countdown icon; optimal design for Chinese character height is 8mm; optimal design for stroke width is a tenth of character height (stroke width: character height = 1:10); optimal design of color is white with a value of R: 255, G: 255, B: 255, and the variety of arrow icons for next turn of the road has less effect on the recognition and readability of the icons. Using the design in this thesis, in indoor simulations and real car experiments, showed that when the range of visibility is 900mm, the time of single glance at and awareness of the name of road in daytime is 0.71 seconds, and in nighttime 0.60 seconds. The results show that the optimal interface design in this thesis is helpful for drivers to recognize the road name in time to decide where to take the next turn on the road.
