http://www.bettscomputers.com/

pages 303-309

People centred systems are designed so that the system fits the users' needs.
[tries to work out what your needs are, and meet your needs]

eg. Google search engine - allows for error and suggests the right input
ATM machine- bank comes to you, friendly user interface (least inconvenience)

Machine-centred system requires the user to serve the needs of the sytem.
-data might have to be in a particular format
-words would have to be spelt correctly
-formatting data and time it has to be entered
-prove identification; retina scan, thumb scanner
-particular location (eg. bank)
[performs a service for you, but may put you at an inconvenience]
eg.Graphics Calculator




Ergonomics is the science of designing the job, equipment and workplace to meet the needs of the worker.
