Engineering psychology focuses on optimizing the interaction between people and machines to improve safety, usability, and user experience, particularly in various industries including healthcare, defense, and consumer goods. The field has evolved from its origins in World War II to address the need for ergonomic solutions and to minimize human error in technology design. Engineering psychologists conduct research to understand user needs and ensure that products are safe, visually appealing, and accessible.

1. Engineering
Psychology
For our comfort, let’s call them EP.

2. What is Engineering Psychology?
• Human factors specialists
• Conduct research on how people work best
with machines
• Focuses on improving and adapting
technology, equipment, and work
environments to enhance human behavior
and capabilities. It is highly related to the field
of ergonomics.

3. Emerge of Engineering
Psychologist
• Originated within experimental
psychology that grew increasingly important
during World Wars I and II.
• This field of psychology emerged during the
1940. Safety concerns and user-friendliness
became a critical issue during World War II
since airplanes and other mechanical devices
were being mass produced

4. Emerge of Engineering Psychologist
• Field of engineering psychology has evolved over
the years since consumers have demanded safer
and ergonomic computers, power tools, chairs,
and other consumer goods.
• Medical errors have also increased demand for
engineering psychologists, says Haydee Cuevas, a
human factors consulting company. )

5. A tiny little facts about EP
• Utilize psychological principles to solve real
world problems. (All psychologist does)
•By minimizing the risks of accidents and
errors, EP make products, systems, and
workplaces safer.
•Analyzing how people interact and use
equipment and technology

6. A tiny little facts about EP
• Exploring ways to make technology more
accessible to people with disabilities
• Surveying populations to learn more about
user needs or to discover which products
appeal to specific demographics

7. Specialized in difference area
• Most engineering psychologists work in industry,
but some are employed by the government,
particularly on Defense projects. They are often
known as human factors specialists.
• Human-computer interaction, aerospace,
usability, human performance, education and
training, virtual reality, health care systems and
technology, product design, workplace safety,
environmental safety, and ergonomics,

8. In designing new products
• Feedback: Implementing consumer feedback
into designs, while ensuring products are safe
and ergonomic
• Human Error: Designing user-friendly and safe
products while eliminating human error

9. In designing new products
• Perception: Designing products that are not
only safe, but also visually appealing
• Profiling: Surveying enough population
samples to ensure products appeal to men,
women, children, college students, etc.

Dutch Lady

11. 1. Does your company hires engineering
psychologist?
– No (I am from FMCG company)
2. Do you think your company need engineering
psychologist?
– We do have industrial psychology, but not
engineering.

12. 3. In your opinion, is your workplace is a safe
place?
– Every manufacturing sites posed significant risk
even on a complete flat floor, you could trip over.
However, safety is a mindset, an awareness that
could keep you alert away from any unforeseen
danger.

– Every manufacturing sites posed significant risk
even on a complete flat floor, you could trip over.
However, safety is a mindset, an awareness that
could keep you alert away from any unforeseen
danger.

14. 5. Do the technology (machine, etc) used in your
company are safe, useful and reliable?
– Yes, the machines are covered with transparent
cover so that each parts can be seen to avoid any
accident.
6. Is there any accident ever has happened in
your company? What are the cause of the
accident, was it human error or machines
error?
– Yes, it is due to human errors who did not follow
instruction properly.

15. 7. Do the technology (machine, etc) used in your

– Consumer complaints are one of our KPI, we take
every complaint seriously and would conduct root-cause
analysis to that issue. Often, we faced
difficulties on defining the actual root-cause as the
defect rate are only about 0.5 ppm.
10.Does your company survey the population
samples about the need for the new product?
– Yes, this is the SOP.
