Within the ongoing process of defining autonomous driving solutions, experience design may represent an important interface
between humans and the autonomous vehicle. This paper presents
an empirical study that uses different ways of unimodal communication in autonomous driving to communicate awareness and
intent of autonomous vehicles. The goal is to provide recommendations for feedback solutions within holistic autonomous driving experiences. 22 test subjects took part in four autonomous, simulated virtual reality shuttle rides and were presented with different unimodal feedback in the form of light, sound, visualisation, text and vibration. The empirical study showed that, compared to a no feedback baseline ride, light, and visualisation were able to create a positive user experience.
