In 2016 Acura showed off its "Precision Cockpit" concept that included a touchpad with 1:1 mapping to a central display. It's supposed to improve on both touchscreens, which can require an awkward reach from the driver to somewhere out of their line of sight, and existing remotes that try to copy a mouse-controlled UI.
Now the company has announced that technology is coming to the 2019 RDX branded as a "True Touchpad." This Android-based car OS is the first use of a touchpad with absolute positioning in a car, making sure that wherever the driver taps on the pad corresponds to what is shown on the central 10.2-inch screen, which is mounted high up, in the driver's line of sight. Combined with a new natural language interface and an interactive heads-up display for the driver, it's supposed to be easier to use than any car software we've seen before.
