Human factors Flashcards
Why are product factors for animals are different?
They have different needs to humans
Why are there stereotypes?
Everyone is unique so we have to stereotype
This puts people into groups
Which can be used to target certain groups
Therefore products can be designed at a need for that group of people
What does inclusive mean?
It’s used for as many people as possible
Impossible to aim at everyone, but usually 5th-95th percentile
What does exclusive mean?
Used for a specific group e.g Children/Elderly/Male/Female etc
What are physiological factors?
Concerned with physical limitations of humans
We all vary in size, strength, stamina etc
We all have similar hand/eye co-ordination skills
What is anthropometric data?
Study of human body and movement of each part
When designing we should use this data to suit your target market
Anthropometric data is measurements taken from millions of people of all shapes and sizes, which is presented in charts
Designers use the 5th-95th percentile so 90% are accounted for
What are ergonomics?
Efficiency of people
Uses anthropometric data
Make things easier to use
Categories during design such as comfort, safety etc
What is a working triangle?
The efficient organisation and management of work space
Range of movement for each task
E.g Kitchens- Work area, oven, cooking hob
Car- Positions of buttons, steering wheel, pedals
What does it mean if a product is adjustable?
Adjusts to different people
E.g Chair- Changes height, changes angle of back support, wheels etc
What are psychological factors?
How the brain works
Works with the five senses ( Touch, taste, smell, sight, sound)
Have to make sure the brain reacts well to the five senses
E.g If smells nice, more likely to buy it. If it looks appealing, more likely to buy it, etc
What are sociological factors?
How people live and work together
Transport design- How much space someone needs on a seat in a bus etc
Size of rooms
Why is disability a problem for designers?
Disabled people rely on others ( this does include babies/young children/elderly as they all rely on others to live life, even though they don’t have any disabilities you would recognise)
So products have to be adapted to try and make disabled people more self-sufficient
Public services are the main issue, so have to adapt them. E.g buses lower the suspension so meet the height of a path for a wheel chari. Large taxis often have an attachable ramp
How do you make a something more accessible to a disabled person?
Lifts Braille Simple controls (for babies/children) Easy to open Restricted packaging (child safety locks)
Name the three human factors
Physiological
Psychological
Sociological
How is safety considered?
Size of components (gap between bars on a cot)
How hot something gets (kettle)
Size of baby products (able to swallow?)
