What is Human Computer Interaction (HCI)
Human-Computer Interaction (HCI) is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design. Source
hereWhy Study HCI
1#To employ people more productively and effectively
– people costs now far outweigh
hardware and software costs
2#People now expect “easy to use” systems
– generally they are not tolerant
of poorly designed systems
– if a product is hard to use, they
will seek other products
3#Errors are costly in terms of
– loss of time & money
– loss of lives in critical
systems
– loss of morale
