A Performance Evaluation on DSK and Qwerty Keyboards
Takeshi Okadome · International Journal of Computer Processing Of Languages · 2007
The performance difference between DSK and Qwerty keyboards is evaluated on the basis of the record of typing contest awards. The resulting estimation with some assumptions is that the expected speed gain of DSK over Qwerty is at least more than 10%. Besides the evaluation, a speed review of some ergonomic studies in the past keyboard performances is also presented and the conclusion is that the design of an optimal human-interface requires the knowledge about human factors.
