Providing Comprehensive Navigational Cues Through the Driving Seat to Reduce Visual Distraction in Current Generation of Semiautonomous Vehicles Methods of interaction and information presentation in the automotive context have continuously been evolving in the last decade Essentially, there is an inherent need to design and research invehicle systems that complement and natively support a multimodal approach towards drivervehicle interaction. Basically, most IVI tasks are classified as secondary or tertiary driving tasks, meaning the driver can allocate lower priority to these tasks as they are not time specific. This is because most visually complex secondary tasks may hinder the driverxe2x80x99s ability to focus on the primary task of driving. However, navigation tasks should not be classified as other IVI tasks. These tasks are often time or location specific and interaction with the system in most cases, may not be optional. Therefore, drivers often get visually burdened with excessive information at the most challenging instances. In this research we propose a novel approach towards resolving this issue by developing a Haptic Seat that can provide continuous and timely navigational information without additional visual distraction.

Investigation of the driverxe2x80x99s seat that displays future vehicle motion Automated driving reduces the burden on the driver, however also makes it difficult for the driver to understand the current situation and predict the future movement of the vehicle. When the acceleration due to automated driving occurs without future prediction, the driverxe2x80x99s anxiety and discomfort are increased compared to the case in manual driving. To facilitate the prediction of the future behavior of the vehicle by the driver, this paper aims to design and evaluate a haptic interface that actuates the vehicle seat. Our system displays to the driver the movement of the vehicle a few seconds in the future, which allows the driver to make predictions and preparations. Using a driving simulator, we compared the conditions where the movement of the car was displayed in advance for the length of different time. The subjective evaluation of the driver showed that the predictability of the behavior of the vehicle were significantly increased compared to the case without display. The experiment also showed that comfortable feeling significantly decreased if the preceding display is too early.
