SOLUTION: A CPU 155 performs calculations and logical operations needed for executing a program. A read-only memory 160 and a random access memory 165 constitute the main memory of the computer. A display interface 175 interfaces a high resolution display 120 to make information from busses visible. An eye tracker 190 is connected to the busses with an eye track interface 189. Then, the tracker controls the information on the display 120 by recognizing the position on the display 120 to where eyes of the user are directed and by selecting a text object based on this position.</p> |
