1.3 Flashcards
physiological factors
factors to do with physical aspects of the body
comfort
freedom from pain or physical discomfort
2 most important aspects of a product
intuitive + comfy
design for discomfort + example
to create a situation where comfort is provided for a limited amount of time (seats in fast food chains, shopping malls, which discourage people from stopping)
fatigue
feeling of tiredness, weakness; happens over time
what can fatigue lead to
MSD (muscuoskeletal disorders)
symptoms of MSD (+ расшифровать)
muscuoskeletal disorder
1 swelling
2 pain
3 range of motion loss
4 inability to perform functions
causes of MSD
1 awkward posture
2 static posture
3 repetitive movements
4 force
considerations for designers in relation to fatigue
performance - designs should reduce fatigue as much as possible
health + safety - fatigued users are more likely to injure themselves or others
biomechanics
analysis of the mechanics of people w the point minimising injuries + improving performance
why do designers consider biomechanics
1 they develop an inclusive design
2 they avoid harming the user
how do you develop an inclusive and safe design
consider:
1 force
2 repetition
3 posture
4 duration
considerations to create an inclusive and safe design
1 force
2 repetition
3 posture
4 duration
when do muscles fatigue fastest
when held in one position for long periods of time
design for inclusion
understanding user diversity and therefore including as many people as possible
advantages of designing ergonomically enhanced work environments
1 healthy workforce
2 enhanced productivity, reduced sick days
3 savings (employers save the money that would otherwise have been spent in compensation)
factors affecting muscle strength
pain
gender
age
training schedule
disability
considerations for designers
adjustability + pleasure
torque
a consideration in biomechanics; twisting force
