Other expansions are sometimes used, such as substituting "mouse" and "mice" for menus, or "pull-down menu" and "pointing" for pointer.
For example, most mobile phones represent actions as icons and menus, but often do not rely on a conventional pointer or containerized windows to host program interactions.
Because programs contained by a WIMP interface subsequently rely on the same core input methods, the interactions throughout the system are standardized.
People with motor impairments, such as Parkinson's disease, may not be able to navigate devices precisely using the traditional mouse pointer for input.
To overcome these barriers, researchers continue to explore ways to make modern computer systems more accessible.
