Designing Interactions Review: Part 1


Good Interaction Design
A well-designed system has:
a. Reassuring Feedback
b. Navigability
c. Consistency

When we design a computer-based system,
a. We are designing not just what it looks like but how it behaves
b. The quality of how we and it interact

a. Doug Engelbart
rsz_20131003_215023Doug Engelbart invented the mouse, and confirmed that it was the best device for pointing and clicking by testing a prototype against a range of alternative options. The mouse became the dominant design. His demonstration of NLS (standing for online System) to the Fall Joint Computer Conference in 1968 changed the world of computing for ever.

b. Stu Card
As Stu Card tested and improved versions of the mouse at Xerox PARC, he developed a supporting science for the design of human-computer interactions, allowing him to predict the likelihood of a design approach being successful. His theoretical understanding helped structure the design space so the movement through it could be more rapid.

c. Tim Mott

Tim Mott created the concept of guided fantasies to learn about user needs, and was one of the very first people to apply rigorous user testing to the design of user interfaces. He also invented a simple version of the desktop metaphor for screen representations of office tasks, called the Office Schematic.

d. Larry Tesler

“Iconic naming systems will be explored. A picture of a room full of cabinets with drawers and file folders is one approach to a spatial filing system.”

Larry Tesler was Tim’s partner in the development of desktop publishing solutions. His many inventions while he was at Xerox PARC include participatory design, cut-and-paste, editable dialog boxes and the Smalltalk browser.
