Intel, along with Carnegie Mellon University, has come up with an idea for a new headlight system that can make rain seem to disappear from the driver's direct line of sight.
According to CNET, the headlight uses a camera housed within the headlight assembly to detect rain (and presumably snow or hail) as it falls, and then it uses a processor to anticipate the path of the rain. Finally, the actual light is created by a projector, which uses the information supplied by the processor to block out the pixels where the rain is expected to be. This technology, as you can see in the image above, should help improve visibility since there will be less light reflected back at the driver by raindrops.
For now, the only way you can see this rain-cancelling technology is in a demonstration in the video report posted below, but Intel thinks that it could make its way into production within the next 10 years.
