| Summary: | 碩士 === 國立清華大學 === 工業工程與工程管理學系 === 102 === This research aimed to conduct a series of user interface improvement against an in-vehicle full voice-based interface named Talking Car and to verify the result of improvement by conducting driving simulation experiments.
According to a previous study, current Talking Car system has some defects on control button and system dialogues with elicitation. For the first part, control button data from 5 brands which are the most popular cars in the market were gathered and analyzed. Then, cooperated with expert advices the control button was redesigned. In the system dialogues part, an experiment was conducted to realize the misunderstood and annoying degree of current guiding sentences. When conducting the experiment, subjects listened and rated degree of understanding and annoying for each system dialogues while driving. After all improvement, another driving simulation experiment was conducted. In this experiment, subjects need to complete the tasks assigned by controlling Talking Car while driving, and task finished time and number of error were collected to verify the effect of improvements.
Under objective statistic data, the final result indicated that task finished time has decreased significantly. The shorter task finished time proved the system is more convenient and easy to use. With regard to evaluation of safety, reacting time of emergency brake were decreased. In consequence, the system is more suitable using in driving. And in the subjective part, subjects are more satisfied with system dialogues of novices and control button. After improvement, Talking Car is easier to use and more fit to the novices. Talking Car provides with consummate functions and intuitive interface.
