Title: Computer input by color coding
Inventor: BROWN MAX R
IPC: G06F3/033
Filed: 1988-04-19
Granted: 1992-03-24
Abstract: ABSTRACT OF THE DISCLOSURE     A display technique that allows the user to input information to a computer in the form of color with character text is disclosed.   he technique provides an ergonomic approach to convey information to an application program by using color to specify functions or attributes.  Colors are used to reduce the number of interactions necessary to accomplish a task between the user and the application program.  In many systems a command has to be typed to save a file.  These commands range in size from one to many characters and require the user to key in each character and the filename.  The improvement described is a technique for typing the filename in a specified color that the application interprets to mean, for example, Save the file.  The technique assigns a color to data elements input to the system.  The color is interpreted by the application to indicate what specific function, attribute or value should be associated with the data element.  For example, if the user enters a file name with a brown background, the application interprets this to mean that the file is to be edited, and should be retrieved for editing if it exists on disk.  Thus, by associating a color with the data element, the specific function to be performed has been relayed without the overhead of additional keystrokes or character information.
