- In 1: Describes time-sharing hardware (65*3K memory + 96M disk), 12 CRTs each with a mouse, keyboard and handset.
- In 2b:
Goal is to develop an "augmentation system" that provides interactive
computer technology to investigate new ways of "conceptualizing,
visualizing, and organizing working material, and in procedures and
methods for working individually and cooperatively"
- In 2c-d: Describes
co-evolution environment. Recognizes that by self-prototyping they may
have limited perspective on external usability, but should be able to
develop some universal principles.
- Thus they are "bootstrapping" from system-development and a
system-development group to other complex tasks being handled by other
types of teams.
- Goal was also to do all of their work online.
Features of Lab and NLS:
- Fully interactive visual workstations, each with a CRT, mouse and keyboard(s) all connected by a time-sharing computer
- Mouse allows user to point at features on the screen
- Better than joystick or light pen for tasks
- Chord keyboard allows efficient interaction with mouse and keyboard interspersed.
- Files are structured so as to reflect the structure of the thought that they represent
- each file is a hierarchy (number represents path in hierarchy
1a2 is the second substatement of the first substatement of the first
statement of the file).
- possible to add cross-references both between and within files
- links by structure or "name" of bookmark
- Manipulable views
- can easily navigate through structure
- can limit depth of view
- can truncate text in viewed levels
- can select content by patterns
- a specification language for these views allows them to be stored and recalled
- Files can be modified both textually and structurally
- Files can be output on a number of devices
- A conference room with multiple terminals
