The development of new hardware is around the corner. In the this day and age, the previous statement is not an earth shaking declaration. Every coupe of month, new commercials and articles come out how the memory is faster and smaller, how storage is bigger in less space, or how the process chip is faster. We are in the age of communication. Computers talking with one another via internet or intranet.
Communication is a big part of computer.
The only way an average person could communicate with a computer is through a keyboard or a mouse. The times are changing. The world of peripherals will make the communications with computers easier to use. For people who have disabilities, this will be an exciting time. Peripherals, such as a light pen, have been used by people with hands.
