Vibrotactile Displays: A Survey With a View on Highly Automated Driving


The task of automotive driving is automated to an ever bigger extent. Within the foreseeable future, drivers can not be required to bit the steering wheel and pedals and may have interaction in non-driving tasks such as working or resting. Vibrotactile displays have the potential to grab the eye of the driving force when the automation reaches its functional limits and the driver has to require over control. The aim of the present literature survey is to outline the key physiological and psychophysical aspects of vibrotactile sensation and to provide recommendations and relevant analysis questions relating to the utilization of vibrotactile displays for absorbing control from an automated vehicle. Results showed that a distinction can be created between four dimensions for coding vibrotactile data (amplitude, frequency, timing, and location), each of that will be static or dynamic. There's a consensus that frequency and amplitude are less suitable for coding info than location and timing. Vibrotactile stimuli have been shown to be effective as simple warnings. But, vibrations can evoke annoyance, and providing vibrations in shut spatial-temporal proximity would possibly cause a scarcity of comprehension of the signal. We have a tendency to describe the sequential stages of a take-over method and argue that vibrotactile displays are a promising candidate for redirecting the attention of a distracted driver. Furthermore, vibrotactile displays hold potential for supporting cognitive processing and action choice whereas resuming management of an automated vehicle. Finally, we tend to argue that multimodal feedback should be used to assist the driver in the take-over method.
