ABSTRACT:
The object of the invention is to change the output conditions of a data processing device in accordance with a user's working state, and thereby reduce user fatigue and stress.
A keyboard is provided as an input device, the time intervals of depression of random pairs of key switches of the keyboard by a user are determined for all the key switch combinations of the keyboard, the scatter of the time intervals of depression of the pairs of key switches is regarded as an arbitrary distribution, a range determined by variance, in an arbitrary proportion, relative to the average value of the time interval distribution is determined, and if the time intervals of depression of arbitrary pairs of key switches by the user is outside this range, the data processing device's output conditions are altered.
