While the world waits for self-driving cars to come of age, this year’s Consumer Electronics Show in Las Vegas is showcasing several emerging technologies meant to benefit human drivers.
BMW, for instance, plans to use holographic technology to create a free-floating screen next to the steering wheel. The full-color display will show controls for, say, air conditioning or in-car entertainment, while a camera detects the position of the driver’s finger relative to the display, allowing them to adjust controls by poking at a screen made of light. It’s not clear when the technology will arrive in cars, but a gesture control system shown off by the automaker in 2015 is already available in production models.
Meanwhile, Ford has announced that it will drag Amazon’s smart assistant, Alexa, out of the home and into the automobile. Passengers will be able to ask Alexa to perform tasks that might usually require paying attention to the center console—making requests for snack stop locations, weather forecasts, or music, for instance.
In both cases, the automakers are clearly looking to keep drivers' eyes on the road. That’s an admirable goal given that distracted driving deaths are on the rise and semi-autonomous vehicles could compound the problem. It remains to be seen, however, where the trade-off lies. Extra convenience and more features that make the cabin feel more like a lounge than a car could conceivably cause greater distraction, rather than attenuating its effects.
That’s a problem that Nvidia’s latest plan could address, though. The company has announced that it wants to use semi-autonomous driving technology to make manual driving safer. The idea is to use sensors that are increasingly dotted around cars, such as cameras and radar, to augment human perception of road conditions. Its system will then intelligently provide cues by using cameras to detect what a driver hasn’t seen.
As well as diminishing the problem of distracted driving, such a setup might be one way to solve what those in the field of autonomous driving call "the hand-off"—the process by which a computer hands control of the vehicle back to a human. Such aids do, of course, need to be used with some caution: manual driving will always require concentration. But if drivers are able to stay alert, they could help make the roads a little safer.
These weird virtual creatures evolve their bodies to solve problems
They show how intelligence and body plans are closely linked—and could unlock AI for robots.
Surgeons have successfully tested a pig’s kidney in a human patient
The test, in a brain-dead patient, was very short but represents a milestone in the long quest to use animal organs in human transplants.
Is everything in the world a little bit conscious?
The idea that consciousness is widespread is attractive to many for intellectual and, perhaps, also emotional
reasons. But can it be tested? Surprisingly, perhaps it can.
We reviewed three at-home covid tests. The results were mixed.
Over-the-counter coronavirus tests are finally available in the US. Some are more accurate and easier to use than others.
