Question 1

spatial relationship

Answer 1

the strategic arrangement and positioning of interface elements to enhance usability, navigation, and user experience

Question 2

dynamic relationships

Answer 2

interactive and responsive connection between a user
and the interface

Question 3

physical relationships

Answer 3

interactions between users and input/output devices,
influencing usability, accessibility, and ergonomic design considerations

Question 4

congruence

Answer 4

mapping is congruent if there is an exact spatial correspondence between controller input and the display output (movement of mouse is same as cursor)

Question 5

CD gain

Answer 5

the amount of movement in a display object, such as a cursor, for a given amount of movement in a control.

Question 6

latency

Answer 6

the delay between an input action and the corresponding
response on a display

Question 7

position control

Answer 7

the sensed property of the input device
controls the position of the object or view on a display (e.g. a mouse).

Question 8

velocity control

Answer 8

the sense property controls the velocity
of the object or view

Question 9

isotonic joystick

Answer 9

the user manipulates the stick
handle, which, in turn, swivels about a pivot-point. The property sensed is the
movement of the stick.

Question 10

isometric joystick

Answer 10

the stick does not move. The property sensed is the force
applied to the stick.

Question 11

Warrick’s principle

Answer 11

control-display compatibility is maximized when the direction of movement of a control matches the direction of movement of the associated display or indicator.

Question 12

natural relationships

Answer 12

relationships that are intuitive and do not require learning
