1988 · Graphics & interaction
Sketchpad turned a display into a place to manipulate geometric ideas.
Visual guide
Create geometric objects.
State relationships between them.
Change the drawing interactively.
Interactive graphics helped open the way to computer-aided design and more direct forms of human–computer interaction.
The display is a view of an underlying model; useful interaction depends on both the model and the interface.
01 · The idea
Ivan Sutherland’s Sketchpad let a user draw and modify shapes interactively with a light pen. The system could preserve constraints such as lines remaining parallel as a drawing changed. It demonstrated that a computer display could support a conversation between a person and a geometric model.

02 · The people
Ivan Sutherland created Sketchpad, a pioneering interactive graphics system developed during his doctoral work at MIT. It let users draw and manipulate geometric objects directly, combining graphical interaction with constraints and reusable structures. His later work advanced displays, virtual reality, and computer architecture. The 1988 award recognized a continuing career of graphics innovation; its contemporary announcement identified his affiliation as Sutherland, Sproull and Associates.

The story
Interactive tools could augment human collaboration, not just automate arithmetic.
