Some human–computer interaction researchers consider WIMP to be ill-suited for multiple applications, especially those requiring precise human input or more than three dimensions of input. Drawing and writing are example of these limitations; a traditional pointer is limited by two dimensions, and consequently doesn't account for the pressure applied when using a physical writing utility. Pressure-sensitive
graphics tablets are often used to overcome this limitation. Another issue with WIMP-style user interfaces is that many implementations put users with disabilities at a disadvantage. For example, visually impaired users may have difficulty using applications when alternative text-based interfaces are not made available. 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. == Moving past the WIMP interface ==
