Alternative Tastenbelegungen sicherer als QWERTY
In einer der wenigen Studien zur Untersuchung von Tastaturbelegungen und repetitiver Fingerbewegung kamen Forscher zu dem Schluss, dass die am häufigsten verwendete QWERTY-Tastenbelegung ein größeres Risiko für CTDs birgt als die Alternativen DVORAK oder ASINREDHOT. (Sowohl DVORAK- als auch ASINREDHOT-Belegungen ermöglichen es Schreibkräften, den Großteil ihrer Zeit auf der Grundreihe zu verbringen.) In einem Artikel,…

Layouts alternativos de teclas são mais seguros que QWERTY
(Entrambi i layout DVORAK e ASINREDHOT consentono ai dattilografi di trascorrere la maggior parte del loro tempo sulla riga di casa.) In un documento da presentare al meeting annuale dell’American Society of Biomechanics, gli autori hanno scoperto che i movimenti angolari delle dita esercitavano una maggiore pressione sul tunnel carpale rispetto alla semplice pressione di…

Layouts alternativos de teclas são mais seguros que QWERTY
Em um dos poucos estudos para examinar o layout do teclado e o movimento repetitivo dos dedos, os pesquisadores concluíram que o mapeamento de teclas QWERTY mais comumente usado pode representar um potencial maior para CTDs do que as alternativas DVORAK ou ASINREDHOT. (Os layouts DVORAK e ASINREDHOT permitem que os digitadores passem a maior…

Alternative key layouts safer than QWERTY
“While the amount of movement on a particular key is exactly the same in the keyboards we used, the problem is the large number of times you have to go to the top and bottom rows using QWERTY,” said Dr. Rick Robertson of the University of Pittsburgh Medical Center. “As soon as you move from…

The Costs of Carpal Tunnel Syndrome
The QWERTY keyboard layout dates from 1873, the same as the barbed wire patents which tamed the American west. A paper from the publication Hand, compared the costs of wrists crippled from Carpal Tunnel Syndrome. In the past, treatments were divided between two options, surgery, or non surgery. In 2006, there were 577,000 carpal tunnel…
