This disclosure relates to systems, devices, and methods for unifying a two-dimensional (2D) interface and a three-dimensional (3D) interface of a computer device, with each interface having unique inputs and displays specific to each dimensionality. The present disclosure provides for identifying a display context value that indicates whether a user is viewing a two dimensional (2D) display of a 2D space or a three dimensional (3D) display of a 3D space of the computer device, as well as identifying an input context value that indicates whether a user input received at an input device is directed toward the 2D space or the 3D space of the computer device, and selecting one of a plurality of operating states of the computer device based on the display context value and the input context value.
