ABSTRACT:
BACKGROUND OF THE INVENTION
1. Technical Field
The present invention relates in general to a method and system for data processing and in particular to a method and system for customizing the output of a data processing system. Still more particularly, the present invention relates to a method and system for customizing the output of a data processing system to meet the needs of a visually or aurally-impaired user.
2. Description of the Related Art
The permeation of industrialized nations by computer technology has dramatically expanded the opportunities afforded individuals with physical impairments. For example, through the use of computers, sometimes in conjunction with specialized input devices, speech impairments no longer inhibit the free flow of interpersonal communication. In addition, individuals with physical impairments that curtail physical labor can succeed economically by exploiting the growing demand for computer programmers, operators, designers, and other technical personnel.
The use of computers to facilitate the communication and economic opportunities of individuals with physical impairments has created a market for specialized computer input devices, such as mouth-pieces and modified keypads, that accommodate the needs of impaired individuals. Because consumers of such input devices form a statistically small, specialized market, the specialized input devices tend to be fairly expensive as compared to conventional computer peripheral devices.
Thus, two computer equipment markets have developed—a first that targets individuals with physical impairments that would otherwise inhibit use of computer systems and a second that targets individuals without physical impairments. The present invention includes a recognition that it would be desirable to develop computer systems that can assist individuals with nominal to moderate physical impairments who are to some extent capable, even with difficulty, of utilizing conventional computer systems.
SUMMARY OF THE INVENTION
It is therefore one object of the present invention to provide a method and system for data processing.
It is another object of the present invention to provide a method and system for customizing the output of a data processing system.
It is yet another object of the present invention to provide a method and system for customizing the output of a data processing system to meet the needs of a visually or aurally-impaired user.
The foregoing objects are achieved as is now described. According to the method of the present invention, a user preference for an audio or visual user output of a data processing system is determined. Next, in response to determination of a user output having a first audio or visual frequency, the user output is mapped to a second audio or visual frequency in accordance with the user preference to obtain a customized user output. Thereafter, the customized user output is presented to the user by the data processing system. In one embodiment, the user preference is determined in response to administration of a test of the user's visual or aural acuity.
The above as well as additional objects, features, and advantages of the present invention will become apparent in the following detailed written description.
