HUMAN FACTORS AND ERGONOMICS TEST
QUESTIONS AND ANSWERS
the study of interactions between people and technology and the factors which
affect their interaction is - ANSWER HFE (human factors and ergonomics)
the goal of HFE is - ANSWER To assure the performance of a system so that
defined users with defined skills and knowledge can carry out defined tasks,
using defined equipment, to defined standards under defined conditions.
a purposefully designed set of elements within a designated boundary is a -
ANSWER system
anatomical human-on-machine interactions include - ANSWER body and limb
posture and movement, force requirements, cycle and frequency of
movement(s), muscular fatigue
physiological human-on-machine interactions include - ANSWER rate of work
effect (O2 requirement, HR, etc.)
psychological human on machine interactions include - ANSWER skill
requirement, mental workload, compatibility
physical human on environment interactions include - ANSWER measurement
of human impact on local environment and associated implications; ex = static
anatomical machine on human interactions includes - ANSWER design of
controls
physical machine on human interactions includes - ANSWER measurement of
machine emissions on human, e.g., noise, vibration, temp.
physiological machine on human interactions includes - ANSWER does
sensory feedback exceed physiological tolerance thresholds.
psychological machine on human interactions includes - ANSWER application
of design to manage input load (compatibility) with user (Human)
, machine on environment interactions includes - ANSWER alteration in local
environment by machine emissions, heat, noise, noxious gases, etc; such as
Engineering changes to minimize emissions
physical / physiological environment on human interactions includes -
ANSWER measurement of conditions and impact, e.g., lighting, noise, temp.
environment on machine interactions includes - ANSWER affect of
Environment on Machine function, e.g., overheating, humidity, etc.; Industrial
hygienists, maintenance personnel, facilities, etc.
4 Methods of Systems Improvement are - ANSWER 1. Designing the user
interface to make it more compatible with the task and the user.
2. Changing the work environment so that people can work productively and
safely.
3. Changing the task to make it more compatible with user characteristics,
education, and
skills.
4. Changing the way work is organized to accommodate people's psychological
and social
needs.
