Summary

The interface between users and the system is important yet difficult to design. Users are error-prone, unpredictable, slow, and forgetful. They need a non-fatiguing interface with a rapid response time. Because no user frequently uses all of a system, the system should be self-descriptive, and easy to learn. Since some are heavy users, the system should be modifiable to allow system tuning. Basically all systems need to handle two kinds of users: the unsophisticated, infrequent user and the frequent user. The frequent user wants a powerful instrument easily adaptable to his needs requiring a minimum of control. Routine operations should be as consistent as possible so they can become reflex actions. The unsophisticated user wants a simple effective tool. He has a job to be done and doesn't care, and doesn't care to know, how the job should be done. In any case the system should show a regular rational exterior regardless of the effort needed to make it rational. With wider use of dedicated computers, user interfaces can be more flexible. (cbb 5/80)

The user interface is the external representation of a system. It uses symbols to communicate the system. Hypertext may be an ideal interface. For example, ZOG/KMS is easy to learn. (cbb 1/88)

Subtopic: adapting to systems up

Quote: people can get used to, and even promote, anything [potaWA_1979]
Quote: the persistence of negative results in user psychology suggests that many interface features are not important [moraTP3_1981]
Quote: users tend to compensate for deficiencies in software; these habits are difficult to change once established [boehBW_1979]
Quote: mastery of a system inhibits desire for change in that system, even if there are serious problems [potaWA_1979]

Subtopic: cognitive dimensions up

Quote: cognitive dimensions for human computer interaction, like mass, length, and time; perhaps cognitive strategy, notation, and the environment [greeTRG_1989]

Subtopic: noun-verb commnds up

Quote: noun-verb commands; specify what first, then give order; gives you time to check the target and make corrections [alzoD_1985]

Subtopic: mobile devices up

Quote: people prefer to view the center of the screen; move list to center before making a selection [hoobS5_2015]
Quote: tapping the center of the screen is the most accurate, followed by the sides, the top or bottom, and the corners; corners require twice as much space as the center [hoobS5_2015]
Quote: fingers get in the way; users will scroll in the middle of a screen for short contents, and on an edge for long labels [hoobS5_2015]

Subtopic: variety of human behavior up

Quote: all people sre temporarily disabled with noise, glare, rain, or distraction; mobile devices should work for everyone all the time [hoobS5_2015]
Quote: your users are not like you; they work in myriad ways, changing the way they work and regularly shifting their grip [hoobS5_2015]
Quote: people change thier hand position on portable devices as they change tasks and contexts; e.g., Hold & Tap, Cradle, 2 Fingers or Thumbs [hoobS5_2015]

Subtopic: UI vs. subject vs. implementation up

Quote: domain of interaction is independent of the domain of implementation and the subject domain [winoT7_1979]

Subtopic: state vs. UI up

Quote: many students confuse an object's state with mechanisms that affect that state [pausR10_1992]

Subtopic: interactivity metric up

Quote: interactivity is characterized by frequency of use, range of choices, and significance of choices [laurB_1991]

Subtopic: bibliography up

Quote: bibliography on user interface and electronic, typographic design [kerrST_1986]
