A method, apparatus, and computer-readable medium for a user interface (UI) for a head-mountable display (HMD). The method includes generating three-dimensional content for display by the HMD. The method also includes identifying three-dimensional coordinates for UI elements of the UI that are associated with the three-dimensional content. The three-dimensional coordinates identified within an angular range for the UI that includes a viewable region of a user while wearing the HMD. Additionally, the method includes, in response to a user input, displaying the UI elements at the identified three-dimensional coordinates over the three-dimensional content. The method may further include, after displaying the UI elements, moving the display of the UI elements on the HMD in a direction corresponding to a movement direction of the HMD in response to detecting movement of the HMD corresponding to movement of a head of the user wearing the HMD.
