To that end, developers are trying to understand what will work best to detect the driver’s state of mind and what signals the car should provide to make sure he is alerted in time to resume control.
Both Matsu and fellow panelist Michael Godwin, North American director-visible LED products for Osram, point to the car’s steering wheel as the new human-machine-interface focal point. The best example of that to date is GM’s Super Cruise Level 2-plus ACC system that uses an infrared sensor to monitor the driver’s eyes and lights up along the steering wheel to signal if all systems are go or about to shut down because the driver’s eyes aren’t on the road.
“We think this is going to be a more prevalent feature in the future,” Matsu says of the interactive steering wheel.
Next-gen models also will see more vivid head-up displays with wider fields of view that will keep the driver informed and engaged, Godwin says. In-cabin lighting may be employed in new ways to signal drivers if the auto-piloting vehicle needs intervention.
A lot of human-factors study is going on to determine what color lighting is most effective, where it should be placed and how fast it should pulse, plus what audible signals should accompany those visual cues, Godwin says. But he notes, near term, the steering wheel will remain the most likely HMI point of focus for ADAS developers, because of its low cost and ease of integration and implementation.
