xv ;;Quote: for interactive computing, we usually attach an interface to a preexisting bundle of functionality

xvi ;;Quote: with interactive programs there is an overwhelming sense of something being in the way; cognitive train wrecks; limitations and constraints

xvi ;;Quote: direct engagement is the ideal of people engaging directly in their chosen activities; with emotional, artistic, and cognitive values

5 ;;Quote: Mac-literal students fail to use 'desktop' anywhere in their descriptions of the Finder

20 ;;Quote: interactivity is characterized by frequency of use, range of choices, and significance of choices

20+;;Quote: a very interactive program should let you do something that really mattered at any time, and it could be anything you could think of--just like real life

20 ;;Quote: interactive if you feel yourself participating in the ongoing action of the representation

20+;;Quote: interactive by orchestrating frequency, range, and significance; by sensory immersion and coupling kinesthetic input with visual response

21 ;;Quote: how can people participate as agents within representational contexts; e.g., actors and make-believe

24 ;;Quote: imprecision of dramatic representation is the price people pay to gain a kind of lifelikeness, surprise and delight

24+;;Quote: when imprecision of dramatic representation works, it is more rewarding with less effort than the precision of programming

78 ;;Quote: provide a potential for action using a selective rendering of the physical world

78+;;Quote: attempting to render the physical world completely would quickly bring the world's most powerful computers to their virtual knees

80 ;;Quote: coincidences in noncomic representations imply agency; people expect that the causes will be revealed

80 ;;Quote: any action is universally understood if its cause is revealed; even if it is something alien to a person's culture; Aristotle

94 ;;Quote: the difference between drama and narrative is enactment, unity of action, and the intensification of emotion and time

113 ;;Quote: engagement is similar to the theatrical notion of the "willing suspension of disbelief"; needed to enjoy a representation of an action

113 ;;Quote: a computer representation of a manuscript or spreadsheet is in fact pretend compared to physical artifacts; it is the activity that is real

114 ;;Quote: in a representational context there is no threat of pain, harm, or unintentional effects; allows a willing suspension of disbelief

115 ;;Quote: the dimension of change is best represented through time, not through past versions

115 ;;Quote: engagement in an interactive system requires a representational context in place of the system itself; no awareness of the system

116 ;;Quote: the proper object of an user interface is what the person is doing with the computer; i.e., don't model what the computer is doing

116 ;;Quote: agency is a key component of first-person experience; even though may describe it without agents, the ability to do something is a criterion

116+;;Quote: engagement in a user interface is a first-person experience

125 ;;Quote: art represents not what is, but something that might be; a wide range of deviations is allowed

126 ;;Quote: the tool metaphor--regardless of what users think they're doing, they are actually using computers to carry out their commands, just like programmers

129 ;;Quote: the problem with interface metaphors is that they are like reality but different and in unknown ways; really a simile

134 ;;Quote: in user interfaces, focus on designing the action
