With fully autonomous vehicles mired in the trough of disillusionment, the industry's focus is shifting towards shorter-term opportunities to use sensor and AI technology to improve human driving performance. To understand where this trend is going, we invited three companies working in this area to stop by our car-based recording studio on the CES floor: we spoke with Nick DiFiore from Seeing Machines, Rana el Kaliouby of Affectiva and Neil Boehm of Gentex. In this free-flowing conversation, we discuss everything from driver monitoring to emotional recognition to the future of rear-view mirrors, all with an eye toward Alex's paradigm of augmented driving.
