OPERATOR PERFORMANCE ON A CHORD KEYBOARD.
The article presents a study on the operator performance of a multiple finger or chord keyboard. A total of 31 chords were ranked according to their difficulty as measured by the reaction times, and a quantitative measure obtained for the distribution. The results were used to predict the average re...

A total of 31 chords were ranked according to their difficulty as measured by the reaction times, and a quantitative measure obtained for the distribution. The results were used to predict the average response times and information rates using subgroups of the chords that involve less choice. It was noted that coding theory could be used to deduce the distribution of the frequency of occurrence of chords with the measured cost function that gives the maximum information rate through the man-machine link. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 1961 holdings: @attributes: islocal: N |
