Abstrakt: Car-sharing system users generally rent a vehicle for a brief amount of time, and they often do not take enough time to learn the controls and functions of a car that they are unfamiliar with. The purpose of this study is to understand the difficulty of controlling a car's functions while driving an unfamiliar car and to redesign controls to improve safety and usability. This study focuses on the secondary controls, such as those for the audio system and temperature system. Fifteen participants were asked to perform simple tasks while driving two different cars: one was their own car and another was a car rented from Zipcar. The participants tended to glance at the controls more often (we counted how many times the participants' glanced at a control) and spent more time completing the tasks in a car rented from Zipcar compared to their own car. Two sets of prototypes (one set was for the center fascia and the other was for the steering wheel) were developed, and a usability study was conducted in a driving simulator to evaluate the usability of the prototypes. We used an eye tracking device and conducted semi-structured interviews for both studies. The results of the usability study indicate that the participants tended to have less difficulty completing tasks using the prototypes in their own personal car when compared to performing the same tasks using a rented Zipcar. Also, the location of controls on the steering wheel and center fascia is recommended for consideration when designing sharing-friendly vehicles. Recommendations regarding the location of controls, such as volume control on steering wheel, are included in this paper. Pros and cons of using eye tracking and driving simulators are also discussed in this paper. [ABSTRACT FROM AUTHOR]
