Comparison of single-Touch and multi-Touch (gestures) operations in-vehicle information system interfaces

This study overviews a car's single-Touch and multi-Touch (gestures) In-vehicle Information system interfaces. A simulated driving environment is established to conduct a fundamental experiment where multi-Touch interfaces are compared with single-Touch interfaces. It adheres to the essential constraints for driver accessibility in a cabinet, including forward-reverse sliding and tilting of the car seat, height and depth of the steering wheel, three-point safety belts, and a mobile supporting arm for a multi-Touch screen. The simulated car cabin tested a vehicle display touch screen around the driver's shoulder position height. The objective assessment is measured by the less time required by participants to complete the task, and fewer errors (mistakes) made by the participants during a task means higher efficiency. The results show that the single-Touch operation was faster than the gesture operation. In terms of error, a gesture has a more significant mistake than a single touch. This study also uses ANOVA to see the difference between the two interfaces in terms of time performance and errors made by participants. This shows that there is a significant difference between single-Touch and gesture operations in errors made by participants. Still, there is no significant difference between single-Touch and gesture operations in performance time despite the single-Touch operation being faster than the gesture operation. © 2024 Author(s).
