Título Investigation of applied forces in alphanumeric keyboard work
Información bibliográfica Jan. 1994, Vol.55, No.1, p.30-35. Illus. 17 ref.
Resumen First, three personal computer keyboards were tested as described by the American National Standard for Human Factors Engineering of visual display workstations (ANSI/HFS 100-1988). Second, keyboard reaction forces were recorded while ten subjects typed four alphanumeric sentences on the keyboards. The peak forces corresponding to each keystroke were 2.5 to 3.9 times the required activation forces, indicating that the subjects consistently displaced the keys to their limits. The average of the peak forces for all keystrokes was lowest for the keyboard with the lowest required activation force. Thus keyboard reaction forces can be used as an index of finger forces for keying tasks.
