Abstract:
The paper discusses the integration of in-vehicle information systems and their impact on driver performance, considering the demands of various types such as visual, auditory, manual, and cognitive. It notes that while there’s a lot of research on optimizing visual and manual systems, less attention has been paid to systems that use both visual and auditory cues or a combination of different types. The study has found that simple tasks cause the least cognitive strain when drivers use touchscreens, while complex tasks are easier to manage cognitively when voice commands are used alone or with visual aids. These results are important for designing car interfaces that effectively manage the driver’s cognitive load.
