Human–computer interaction studies the design and use of computer technology, focused on the interfaces between people and computers. the information provided is often subjective and may be selective. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design. 7.4.4 Query techniques....................... 38 atomic elements of speech that represent a distinct sound.
