Heads-up display GPS with Virtual Cable
Two things plague GPS users: being forced to deal with dubious direction vocalizations and the amount of time spent looking at the screen when you should be paying attention to the road. MVS is developing a solution and it's likely the most revolutionary concept to date.
The system is comprised of a series of mirrors that project a three-dimensional line onto the windshield giving drivers a heads-up display of their intended path of travel. The Virtual Cable shown above the top of the windscreen is usable at night and seems to integrate cleanly into the surrounding environment, allowing users to focus on the road and simply use their peripheral vision to guide them.
