246 ;;Quote: can point with a mouse as fast as with a finger; a Fitts's law device

244 ;;Quote: Star and Alto use a bit-mapped display

248 ;;Quote: use task analysis for user interface design; who are the users, what information do they use, and what methods

248 ;;Quote: after task analysis, build a new task environment for the user for the same goals

248 ;;Quote: Star based on the Alto; 1000 Alto's were built over a period of 8 years; one of largest prototyping efforts

248 ;;Quote: Star emphasized the easy concepts of concrete, visible, copying, choosing, recognizing, editing, interactive; and avoided their opposites

248 ;;Quote: the conceptual model of a system enables the user to understand and interact with the system

252 ;;Quote: documents should be more than file names; represent by icons, select with a mouse

252 ;;Quote: with icons, moving a document is the same as moving a piece of paper to a file

252 ;;Quote: the user's conceptual model is important because it changes the system's functionality

254 ;;Quote: in an office everything arrives by mail, so in Star messages are documents and documents are mailed

256 ;;Quote: Star's user interface resembles a desktop

256 ;;Quote: Star's desktop is an array of 154 squares; icons are centered in squares

258 ;;Quote: a record file is a collection of fields; can display records in a table or as a form with fields; query by example

258 ;;Quote: a well-designed system makes everything relevant to a task visible on the screen; aids memory

260 ;;Quote: when everything is visible, the display becomes reality, the user model; actions understood by visual effects; can conduct experiments

260 ;;Quote: Star eliminates the CODE key since it leads to invisible resources

262 ;;Quote: every key and command has a visual response; otherwise user model is destroyed

262 ;;Quote: most Star objects described by a property sheet; a form that can be displayed and modified

262 ;;Quote: property sheets support progressive disclosure by hiding complexity until needed

262 ;;Quote: the screen shows the visible characteristics of an object while a property sheet gives its underlying structure

264 ;;Quote: command parameters by an option sheet (a form); reduces memory requirements

264 ;;Quote: WYSIWYG is 'what you see is what you get' for document creation; eliminates iterations required with formatters

268 ;;Quote: Star has universally applicable commands: move, copy, delete, show/copy properties, again, undo, and help

268 ;;Quote: MOVE (dragging) is the most powerful command in Star; move graphics, formulas, files, mail, printing

268 ;;Quote: in Star you set margins by selecting a paragraph and changing its MARGINS property

268 ;;Quote: a user interface should be consistent; e.g., always select with the left mouse button

268 ;;Quote: consistency is hard to achieve in a user interface; use common paradigms where possible, e.g., editing

270 ;;Quote: in Star, editing is a common paradigm; used for managing files, working environment (desktop), and properties

272 ;;Quote: Star's file drawers and mail in-baskets are also databases; can be queried

272 ;;Quote: with Star, you create by copying; easier to modify than to create, e.g., icons and graphics

274 ;;Quote: all data icons treated uniformly; moving/mailing/etc. documents, folders, and record files

274 ;;Quote: simple things should be simple; complex things should be possible

276 ;;Quote: Star uses a two button mouse instead of three; increased consistency and simpler semantics

276 ;;Quote: critical parts of a system should be tested on users

276 ;;Quote: minimizing the number of keystrokes may not make a system easy to use; want overall simplicity

276 ;;Quote: a mode is a user interface state for interpreting operator input; not associated with an object

276 ;;Quote: Star commands specify the object and then invoke the command; noun-verb

276 ;;Quote: use noun-verb commands since have more judgment in selecting an object and can change selection

276 ;;Quote: insert text in Star by making a selection and begin typing

278 ;;Quote: to move an object in Star, select it, push the MOVE key, and then select the destination

278 ;;Quote: Star modes (e.g., for moving) work because Star posts a message, changes the cursor shape, and restricts the actions

278 ;;Quote: can initialize a blank document with a formatting layout, fixed text, graphics, and fields; acts as a form

278 ;;Quote: can set up 'transfer sheets' that contain useful graphics symbols

280 ;;Quote: can define multiple views of a record file; specify a filter, a sort order, and a formatting document

280 ;;Quote: fields in a Star record file displayed via a formatting document whose names correspond to fields; no inherent external representation

280 ;;Quote: use Star's CUStomer Programming Language (CUSP) to write computation rules for fields
