✦ Synopsis
tested in various ways, and were observed and photographed while operating teleprinters. The load on each finger of the telegraphist and typist conferred by the standard keyboard was analysed and found to be maldistributed, the ring and little fingers being overloaded. Other features of keyboard design and work layout were identified as likely sources of inefficient operating postures and thus probably of symptoms in operating. An alternative keyboard layout is suggested which overcomes maldistribution, and to some extent the probable sources of postural difficulty. The results of the study support other changes to keyboard design suggested by Klockenberg nearly 50 years ago.
