Holographic display in future automotive smart cockpit: application scenarios, interaction modals, and VACP analysis

Three-dimensional holographic display can provide more possibilities for the human-machine interaction in the future smart cockpit. In this paper, potential application scenarios and interaction principles of holographic display in the future automotive cockpits are predicted. VACP model is utilized to validate the interaction principles, based on the analysis and evaluation of existing and potential cutting-edge holographic display technologies. Two application patterns are set up: before 2040, the role of driver still exists due to the development of automated driving technology, participants will include only passengers after 2040, which means different interaction models and logics. After 2040, direct air projection technology will be applied, which is medium-free and with better interactive performance. Based on proposed principles, models as well as a series of user survey, application scenarios in the future cockpit are assumed. Through systematic technical analysis by cooperating with a prominent automobile OEM and other related industrial cooperators, this paper provides the principles and application concepts of holographic display in the future cockpit and obtains the evaluation and test methods for holographic display technologies in these concepts at the same time.
