- - - - satisfy the
        machine requirements.
    - - Human Engineering or adaptation of the machine to man.
    - - man-machine system.
    - - U.S
        
        human factor engineering y
        engineering psicology
    - - Ergonomics
        
        is based on human engineering
    - - consider ergonomics as a science of physiologists and doctors
- - - - Heavy work must not exceed the capacity of each worker
      - Heavy physical work must alternate throughout the day
      - Heavy physical work must alternate throughout the day
  - - - That is to say
        
        to the set of psychophysical requirements to which the worker is subjected throughout his working day
- - - - the volume assigned to one or more people, as well as the means of work that work together with
        he (or they) in the work system to accomplish the task
    - - anthropometric and
        physiological of the human being
      - job in physical appearance
      - psychosocial conditions
  - - - allow the worker to modify the position of the body
      - include different tasks that are mentally stimulating
      - leave some latitude to the worker to make decisions
      - give the worker the feeling that they are doing something useful
      - provide adequate training so that the worker learns what tasks must
        perform and how to do them
      - facilitate adequate work and rest hours thanks to which the
        worker have enough time to complete tasks and rest
      - leave a period of adjustment to new tasks, especially if they require great physical effort, so that the worker gradually gets used to their work
- - - - The height of the work surface must be at least that which allows to establish the optimal position: horizontal thighs, vertical legs, relaxed shoulders, arm and forearm forming a right angle from the elbow or forearm
        tilted slightly down
    - - determined by two distances
        
        At knee level
        
        At ground level
      - The depth will be at least that which allows the required media to be placed at a correct viewing distance (for example: screens, visual media, etc.).
    - - These must be of sufficient size to allow the task to be carried out comfortably, and flexibility in the placement of the work tools. At least the width will be that corresponding to the measurement between the elbows of the 95th percentile man (approximately 50 cm.).
