Quote: seeing and pointing is preferred over remembering and typing; reduces burden on memory [»smitDC_1982]

Quote: most interactions with a system are related to recent events; pronoun reference by pointing to portions of these events [»teitW3_1977]

Quote: with Smalltalk, needed little typing; most interaction through mouse and window menus [»morgC8_1981]

Quote: over 90% of executed KMS commands by pointing at an item [»akscRM7_1988a]

QuoteRef: goldA3_1976 ;;5 Mouse for pointing by the user

Quote: Apple Desktop Interface paradigms--select object then select action via a menu, or drag an object to another object representing an action [»apple_1987]

Quote: selecting before committing to action allows exploration and mistakes; because selecting has no other effect [»apple_1987]

Quote: if a Smalltalk command takes one parameter, select the item and invoke the command; allows you to change selection or command [»teslL8_1981]

Quote: remove modes from Smalltalk editing by selecting before command, and text replaces selected characters [»teslL8_1981]

Quote: Star commands specify the object and then invoke the command; noun-verb [»smitDC4_1982]

Quote: to move an object in Star, select it, push the MOVE key, and then select the destination [»smitDC4_1982]

Quote: selecting a menu item with a mouse requires a distinct physical mode; yet designed as a modeless system [»buxtW_1986]

Quote: with Smalltalk instead of typing the name of a procedure, you point to it in a list or activate its window [»teslL8_1981]

Quote: point-and-click is 90% of a user's interaction with KMS; twice as fast as menu selection [»akscRM7_1988a]

Quote: experienced users find the mouse faster and more accurate; novices did better with a light pen or knee control [»englWK3_1967]

Quote: can point with a mouse as fast as with a finger; a Fitts's law device [»smitDC4_1982]

Quote: derive Fitts' Law by assuming that the relative accuracy of movement is constant; the measured time for acquiring a target is within the computed range [»cardSK_1983]

Quote: Fitts' law also applies to constrained movement: speed of movement is linearly related to the normal constraint [»accoJ3_1997]

Quote: comparison of constrained pointing tasks and goal-crossing tasks for speed and accuracy [»accoJ4_2002]

Quote: fastest was orthogonal pointing and continuous orthogonal crossing; slowest was continuous collinear crossing [»accoJ4_2002]

Quote: movement time for pointing and goal crossing by the target-distance to target-width ratio

Quote: orthogonal pointing was 10% faster than collinear pointing [»accoJ4_2002]

Quote: for targeting tasks, the rate of performance increases uniformly as movement amplitude decreases and tolerance increases [»fittPM6_1954]

Quote: use point-completion deadlines to separate pointing time from search time in usability studies [»hornAJ9_2001]

Quote: search for upper-left targets faster than lower-right targets; 2x to 4x; roughly linear for three column layout; lower middle targets slower [»hornAJ9_2001]

Quote: 1/5 second search time for target-only layouts; independent of position

Quote: discrete orthogonal pointing had the lowest error rate, 2.5%; others similar to Fitts' collinear pointing, 7.6%; target distance and width was significant [»accoJ4_2002]

Quote: when practical for crossing, use orthogonal goals to the movement direction

Quote: goal crossing may be better than pointing; continuous action; bi-directional; double crossing; multiple selection; like gesturing [»accoJ4_2002]

Quote: goal crossing may work better for elderly users who have difficulty pointing and double clicking [»accoJ4_2002]

Quote: special command to place cursor at an optional component [»teitT6_1979]

Quote: use the steering law for trajectory-based tasks; like Fitts' law [»accoJ5_1999]

Quote: the Macintosh menu bar is about twice as fast as the Windows task bar; widgets on the border should extend to infinity [»accoJ4_2002]

Quote: for older adults, use a cursor with a large hot spot and sticky icons [»wordA3_1997]

Quote: fingers have a bandwidth of 17.6 bits/s; four times that of a mouse; can a device use this? [»cardSK4_1991]

Quote: selecting a graphics object in Lisa displays handles for moving or modifying the object [»willG2_1983]

Quote: selected objects in SUIT display black handles with a 1-pixel wide white border; always visible [»pausR10_1992]

Quote: SELECT mouse button for selecting objects and ADJUST mouse button for broadening or narrowing the selection [»smitDC_1982]

Quote: click the mouse button once to select an item, twice to open a window; Preference's tool to adjust [»stewG3_1983]

Quote: invoke icon animations when cursor inside the bounding box; users moved cursor to edge of box [»baecR4_1991]

Quote: in Magpie, whenever an item is selected, descriptive information is displayed in an adjoining pane [»deliNM5_1984]

Quote: use mouse to display the default value and likely alternatives for a field [»maloTW4_1987]

Quote: avoid jitter in remote mouse control by averaging data from last 7 points [»myerBA11_1998]

Quote: Sketchpad tracks the pseudo pen location, a bright dot at the nearest drawing part; used for drawing operations [»suthIE5_1963]
