Investigation on the Effectiveness of Autostereoscopic 3D Displays for Parking Maneuver Tasks with Passenger Cars

Abstract

Intelligent parking assist systems are a common feature of modern vehicles. They provide assistance during maneuvering and parking of cars. While current vehicle backup cameras are an effective solution, the absence of spatial depth may lead to misjudgments and uncertainty, leading to material or personal damage. A novel approach to reduce this risk is the implementation of autostereoscopic displays which provide the user with a perception of the depth in a scene. This added spatial information enables better judgements of positions and distances for displayed objects. If implemented into parking assistance systems, effectiveness is increased by providing better distinguishable spatial relationships. The presented study is aimed to determine whether the use of an autostereoscopic display (i) improves the driver’s spatial orientation and if this increase in information (ii) results in a measurable improvement of the parking performance. Results show that there is a tendency towards a stereoscopic parking assistance, but no significant effect were found.
