Objective: The aim of this study is to derive the expected behavior of occupants in a fully autonomous driving environment and to explore the display technology and related requirements.
Background: With the rapid development of technology, the commercialization of autonomous vehicles is becoming visible. Many car manufacturers are focusing on supporting a variety of behaviors for the great 'in-vehicle experience' of passengers.
One of the essential factors for providing 'in-vehicle experience' is 'display' in the vehicle. However, research that embodies ideas of display inside autonomous vehicles is insufficient. Therefore, to provide great "in-vehicle experience" through display in a autonomous driving environment in the future, it is important to understand the requirements from the passengers inside autonomous vehicles.
Method: First, expected behaviors in autonomous vehicles were derived through user interviews using online video conference platforms. Subsequently, display technologies and requirements based on in-vehicle expected behavior were explored through the co-design workshop.
Results: The main expected activities in autonomous vehicles were 'media viewing' and 'work'. Regardless of expected behavior, there was a strong demand for 'frontal visibility'. Additional demands such as "immersion" for "media viewing" and "efficiency" for "work" were required. Based on this, exploration of the display technology resulted in "rollable display" and "transparent display", and additional "appearance cleanliness" and "screen quality" required for each.
Conclusion: Display technology required according to expected behavior was different.
As a result, the requirements for displays were also different. However, regardless of the expected behavior and display technology, the demand for 'frontal visibility' has become common.
Application: The results of the interview and analysis might help to guide usercentered value to consider when designing display inside autonomous vehicles.
