Ergonomics – study of designing equipment and devices that fit the human body, its movements, and its cognitive abilities. Branches of ergonomics ...
The two hands should begin motions at the same time. The two hands should not be idle at the same time except during rest periods. Motions of the arms should be made in opposite and symmetrical directions and should be made simultaneously
Because cognitive ergonomics is a small priority for many, it is especially important to diagnose and help what is needed. A comparison would be fixing what does not need to be fixed or vice-a-versa. [citation needed] Cognitive ergonomics aims at enhancing performance of cognitive tasks by means of several interventions, including these:
Cognitive ergonomics and cognitive engineering - studies cognition in work settings, in order to optimize human well-being and system performance. It is a subset of the larger field of human factors and ergonomics. Applied psychology - The use of psychological principles to overcome problems in other domains. It has been argued that engineering ...
Therbligs are elemental motions used in the study of workplace motion economy. A workplace task is analyzed by recording each of the therblig units for a process, with the results used for optimization of manual labour by eliminating unneeded movements.
[4]: 385 Consideration of physical ergonomics suggests the most relaxed typing position is one in which the keyboard user's forearms are parallel to the ground, with wrists held straight. To facilitate this posture, Klockenberg published a study in 1926 that suggested the primary key clusters for two-handed typists should be split into left and ...
