The latest patent to surface from Honda could add the touch dimension to window tints, should it come to mainstream application. While electro-photochromic windows have seen automotive applications before, Honda’s patent allows touchscreen-like control by varying the windows’ tinted area with the user dragging a finger across the window surface.

Pinch movements would be used for controlling other parameters of the window tint, though with safety in mind, these functions can only be accessed when the vehicle is stationary. Though the patent image suggests its application for a vehicle’s side windows, the technology could be applied to the front windscreen as well, which could see it replace physical sun visors in the role of blocking out the sun’s glare.

What do you think of this new approach to window tinting? Will touch surfaces continue to lead the way forward, or would you prefer more tactile, physical controls?
