Computer Interface Design

Paper Summary:

This paper explains that the computer interface includes both the hardware and software that enables the user to ask for information, to input data, to give command, and to get the computer to perform processes as needed. The author points out that the design of the interface is achieved by considering the role of the hardware and software, the demands of the user, and the physical, cognitive, psychological and even emotional needs of the user. The paper emphasizes that the user wants the hardware and software to provide its service as easily and effectively as possible. The author underscores that the field of interface design has expanded along with the many computer systems people access, such as PDAs, cell phones, MP3 players, DVD recorders and cable boxes.

From the Paper:

"Of course, the cell phone has become more complex and often uses an interface with which the consumer is not familiar. This has become an issue as the telephone tries to offer more and more services and more and more processes that can be accomplished with the cell phone. A related issue is that the size of the cell phone has been much reduced, leaving many users with a keyboard they can barely access without making a mistake. The problem of small size also plagues PDAs and laptops and adds to the difficulty involved in interface design."
