Evaluation and Improvement of Dvorak Keyboard Layout Using CADWORK

Abstract:

Article Preview

The keyboard layout proposed by Dvorak has been evaluated and improved by CADWORK. Data prepared with characters of the Dvorak layout were fed into CADWORK to search for improvement. The criterion employed by CADWORK for evaluation is the cycle time simulated using methods analysis of operations data. An improved layout was generated yielding a cycle time of 616.09 TMU while the Dvorak layout yielded a time of 622.69 TMU. A test to determine acceptability of the CADWORK improved layout using experienced keyboard users indicated that some participants typed faster with the CADWORK layout than others using the Dvorak layout.
