Physiological Factors
Physiological Factors
Physiological factors encompass the physical aspect of the body. Designers use a range of physiological data to inform their design decisions. Some physiological factors that they may consider are:
Muscle strength in different positions: How strong a muscle is in different positions.
Endurance in different positions (how long a position can be maintained before discomfort sets in)
Visual acuity (how well the user can see under different conditions)
Tolerance to hot or cold temperatures
Range of frequencies that can be heard by humans
Hand/eye coordination
Comfort & Fatigue
Comfort & Fatigue
Comfort: This various between people. For instance the type of bed that a person will choose is determined by the firmness of the mattress.
Fatigue: When people are put under physical or mental stress/activities for extended periods, fatigue can set in. People react differently when they are fatigued. Errors can creep in which then could prove dangerous. Designers need to understand peoples tolerances and design products and environments that help to reduce fatigue.
The premise for Design for discomfort is to create a situation that provides comfort for only a limited amount of time. This approach has been adopted by airports, fast food chains, shopping malls, supermarkets and bus stations.

The design is to facilitate movement, to avoid loitering and to discourage people resting or stopping for long periods of time. This conversely will encourage movement to retails facilities.

Fatigue
Fatigue is the temporary diminishment of performance. Fatigue can be physical and/or mental. Fatigue can inform design decisions and can affect users.

Biomechanics in human factors
Biomechanics in human factors
Biomechanics in human factors includes the research and analysis of the mechanics (operation of our muscles, joints, tendons, etc.) of our human body.
The importance of analysing the biomechanics in the use of a product of a given artifact is crucial to ensure the well-being of the user. Factors to consider include posture, muscle strength and age of the target user and how they interact with the product which might include the handle size, surface texture, and torque required.
Biomechanics in human factor design deals with four key criteria:
