Sony has obtained a patent for a new controller design that ditches all buttons in favour of a touch interface. The controller would come with optical sensors that register touch-based inputs. The new controller design would be fully customisable, allowing users to resize, remap, and remove buttons to their liking.Sony has obtained a patent for a new controller design that ditches all buttons in favour of a touch interface.
