Study of Rotating Seat that Improves Vision of the Interior of an Automobile

Recently, the demand for improvement of passenger comfort in automobiles has increased. An automobile does not have a large amount of volume to physical space, and space planning of the seat arrangement greatly influences passenger comfort. The seat arrangement changes the visual environment of the passenger. Previously, the authors proposed a technique to evaluate comfort through the seat arrangement by using the passenger’s space and vision. In this evaluation technique, vision is recognized as volume. A useful seat arrangement with a rotated seat utilizes the effect of vision for improving passenger comfort. In this paper, a sensory evaluation and a biomedical measurement are performed. Therefore, the effectiveness of a seat arrangement with rotated seats is shown to improve passenger comfort.
