Microsoft shows off next-gen Windows for connected cars

In the prototype Teixeira showed, the in-dash screen needs to do more than just “blast the UI” from the phone to the screen, he said. Microsoft is working on four things: reducing the “cognitive load,” or the requirement to think about what you’re doing; glanceability, or minimizing the “eye time” on the screen beyond 2 seconds; trying to minimize the effects of different screen sizes; and doing away with the need to touch tiny little virtual buttons—which might be OK on a phone, but much less so at 65 MPH. Most of the time, that interface should be voice-driven, essentially, by Microsoft’s Cortana technology.
