ABSTRACT:
The present invention describes a device and a method to prevent RSI symptoms when keys are operated, and it contains a measuring device (4) to determine the force acting on the key, a device to compare the measured force with a finger stress model, and a device to make critical finger impact values (14, 16) perceptible. The inventive device may be positioned directly on the keyboard (2) as a stand-alone device, or it may be designed as part of a data processing system.
