● aka human factors

● A body of knowledge about human abilities, human limitations and other human characteristics that are relevant to design

● Focuses on human and their interactions with the environment

Ergonomics

● A body of knowledge about human abilities, human limitations and other human characteristics that are relevant to design

Ergonomics

● Focuses on human and their interactions with the environment

Ergonomics

● First commandment of human factors

● Ergonomists design environments and products according to the physical (visual, auditory, tactile, strength, anthropometric), cognitive (learning, information processing, retention), and psychosocial (cultural influences, behavior, background) characteristics of humans.

“Honor Thy User”

● Ergonomists design environments and products according to the physical (visual, auditory, tactile, strength, anthropometric), cognitive (learning, information processing, retention), and psychosocial (cultural influences, behavior, background) characteristics of humans.

“Honor Thy User”

● Science of measurement of the human body, provides therapists with building blocks for understanding the complexities of the human form and how it interfaces with its environment

Anthropometry

● Science of measuring length, breadth and width in the human population

Static Anthropometry

Considerations in Anthropometry

GENDER DIFFERENCES

ETHNIC DIFFERENCES

AGING

OCCUPATIONAL DIFFERENCES

Considerations in Anthropometry

Men are generally larger than women, both overall and in limb length

GENDER DIFFERENCES —

TRUE OR FALSE:

● Males tend to accumulate fat tissues in the abdomen while females accumulate at the hips, thighs, and buttocks

TRUE

Considerations in Anthropometry

Different ethnic groups have different anthropometric measurements

ETHNIC DIFFERENCES —

TRUE OR FALSE:

● Black Africans have proportionally longer lower limbs than Europeans

● Whereas Asians have proportionally shorter limbs

TRUE

TRUE OR FALSE:

● Europeans have proportionally longer lower limbs than Black Africans

● Whereas Asians have proportionally longer limbs

FALSE:

Correct answer:

TRUE OR FALSE:

● Black Africans have proportionally longer lower limbs than Europeans

● Whereas Asians have proportionally shorter limbs

Considerations in Anthropometry

Anthropometric changes during adulthood are more subtle

3. AGING —

AGING: Fill in the blanks

● As people pass beyond ____yo, stature decreases and bodyweight increases

● After ____yo for men and ____yo for women, bodyweight decreases because nagseselan na panlasa nila during that age

AGING: Fill in the blanks

● As people pass beyond 30yo, stature decreases and bodyweight increases

● After 50yo for men and 60yo for women, bodyweight decreases because nagseselan na panlasa nila during that age

TRUE OR FALSE:

● As people pass beyond 30yo, stature decreases and bodyweight increases

● After 50yo for men and 60yo for women, bodyweight decreases

TRUE

TRUE OR FALSE:

● As people pass beyond 30yo, stature increases and bodyweight decreases

● After 50yo for men and 60yo for women, bodyweight increases

FALSE

Considerations in Anthropometry

The tendency for people of different occupations to have different anthropometric proportions is poorly understood.

OCCUPATIONAL DIFFERENCES —

● The person stands erect and looks straight ahead, with his or her arms in a relaxed posture at the side

Standing Posture

● The person sits erect and looks straight ahead

● The sitting surface is adjusted so that the personʼs thighs are parallel to the floor and the knees are bent to a 90-degree angle with the feet flat on the floor.

● The upper arm is relaxed and perpendicular to the horizontal plane, and the forearm is at a right angle to the upper arm and thus also parallel to the floor

Seated Posture

● The person sits erect and looks straight ahead

Seated Posture

● The sitting surface is adjusted so that the personʼs thighs are parallel to the floor and the knees are bent to a 90-degree angle with the feet flat on the floor.

Seated Posture

● The upper arm is relaxed and perpendicular to the horizontal plane, and the forearm is at a right angle to the upper arm and thus also parallel to the floor
