System users often judge a system by its interface rather than its functionality. A poorly designed interface p Can cause a user to make catastrophic errors. p Is the reason why so many software systems are never used. 4 https tailieudientucntt Human factors in interface design Limited short-term memory p People can instantaneously remember about 7 items of information. If you present more than this they are more liable to make mistakes. People make mistakes p When people make mistakes and systems go wrong inappropriate alarms and messages can increase stress and hence the likelihood of more mistakes. People are different p People have a wide range of physical capabilities. Designers should not just design for their own capabilities. People have different interaction preferences p Some like pictures some like text. 5 https tailieudientucntt UI design principles UI design must take account of the needs experience and capabilities of the system users. Designers should p be aware of peoples physical and mental limitations . limited short-term memory and p should recognise that people make mistakes. UI design principles underlie interface designs although not all principles are applicable to all designs. 6 https tailieudientucntt UI design principles User .
