Richardson, Rose Mae M., Telson, Ronald U., Koch, Christopher G. and Chrysler, Susan T. (1987): Evaluation of Conventional, Serial, and Chord Keyboard Options for Mail Encoding. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 911-915.

“The motivation for the experiment was the integration of a work station display component and a suitable data entry device. Keying performance with three candidate keyboards was evaluated: (1) a one-handed conventional calculator keyboard, (2) a two-handed 10-key serial keyboard, and (3) a two-handed 10-key chord keyboard. Subjects were trained to criteria on a numerical data entry task and subsequently tested for performance in encoding five-digit strings. Measures of encoding response time and encoding errors showed a substantial advantage in training time for the calculator keyboard and two-handed serial keyboard over the two-handed chord keyboard.”
