Technical setup of a Wizard-of-Oz vehicle for on-road AI data collection

This paper presents an implementation of a new solution that improves data collection for artificial intelligence (AI) applications with a Wizard-of-Oz (WoZ) vehicle. It allows to immerse test participants in on-road studies into experiences of not yet existing systems. As measurement technology, the paper focusses on a stereo camera Advanced Occupant Monitoring System which detects driver activities in real time and further allows to collect AI training data for activity and driver state classification. Three application areas for data collection with this setup for automated driving are presented: Support for level compliant behaviour of drivers, identification, and influence of motion sickness on driving ability and improving proactive interaction of smart assistants with vehicle passengers. To constantly adjust and improve hard- and software to the data collection requirements of the different applications, the modular vehicle setup and data collection procedure can be adjusted in an iterative process.
