Ford Motor Company, as the final phase of its research into the cause and effects of distracted driving, is utilizing high-tech goggles that measure the amount of time drivers take their eyes off the road to help validate in-vehicle technologies such as GPS navigation systems.
The special “occlusion” goggles are used in testing at Ford’s Human Machine Interface Verification Laboratory – or “Distraction Lab.” Ford engineers and technologists use the data to accelerate the safer design of telematics systems that keep drivers connected and informed.
In occlusion studies, the test subject wears goggles equipped with small liquid crystal display (LCD) screens that rapidly blink open and closed in a regulated sequence while the subject views graphics and text information on a new device such as a navigation screen. Open goggles represent eyes-off-road time, or when the driver is looking away at a device. Closed goggles represent eyes-on-road time.
If 85 percent or more of test subjects are able to complete a task on screen in the time allowed – such as reading and selecting an address on a navigation screen – the task is considered compliant with industry guidelines. However, if the test subject cannot complete the task in time, the function is designed to be locked-out when the vehicle is in motion, and can only be operated when the vehicle is stopped.
Based partly on occlusion testing, the information displayed on Ford’s latest-generation navigation system is purposely limited to comply with industry guidelines and help reduce the risk of driver distraction.
