The User-Interface Technology Branch at NCCOSC RDTE Division has been conducting a series of studies to address the suitability of commercial off-the-shelf COTS graphic user-interface GUI methods for efficiency and performance in critical naval combat systems. This paper presents an advanced selection algorithm and method developed to increase user performance when masking selections on tactical displays. The method has also been applied with considerable success to a variety of cursor and pointing tasks. Typical GUIs allow user selection by 1 moving a cursor with a pointing device such as a mouse, trackball, joystick, touchscreen, and 2 placing the cursor on the object. Examples of GUI objects are the buttons, icons, folders, scroll bars, etc. used in many personal computer and workstation applications. This paper presents an improved method of selection and the theoretical basis for the significant performance gains achieved with various input devices tested. The method is applicable to all GUI styles and displays sizes, and is particularly useful for selections on small screens such as notebook computers. Considering the amount of work-hours spent pointing and clicking across all styles of available graphic user-interfaces, the costbenefit in applying this method to graphic user-interfaces is substantial, with the potential for increasing productivity across thousands of users and applications.
