Investigation of Touch Screen based User Interface in a Driving Context

다국어 초록 (Multilingual Abstract)

Objective: This study aims to investigate the effects of in-vehicle information systems (IVIS)’ tasks based on visual-manual interaction and provide design guidelines for touchscreen-based IVIS. Background: The understanding of driver behavior when interacting with touchscreen-based IVIS is very low although the functions of IVIS become complex. Method: A driving simulation study was conducted to achieve the research objective. In the experiment, the participants were asked to perform item searching tasks, hierarchical menu tasks, and touch gesture tasks to observe driving safety-related behaviors, including driving performance, visual distraction, secondary task performance, and subjective workload. Statistical analyses and modeling techniques were applied to analyze the data. Results: The results showed that driving safety-related behaviors were influenced depending on design variables of the touchscreen of IVIS. Conclusion: This research provides insights for both researchers and practitioners on the design of IVIS in terms of driving safety.
