1940s – 1960s mputers : Tools for Calculation and Co Comp Symbolic Manipulation 2

1945 Co Comp mputer ers : tools to augment human cognition Vannevar Bush’s vision of computers 3

Memex inspired the First Graphical User Interface 1963: Ivan Sutherland’s CAD software, Sketchpad 4

Memex inspired the first interaction devices 1968: Douglas Engelbart’s mouse 5

Memex inspired the Internet 1969: ARPANET’s 6

The result of the Memex vision? NAILED IT! 7

What comes next? September 1991 8 Scientific American

“The most profound technologies are those that disappear . They weave themselves into the fabric of everyday life until they are indistinguishable from it.” Writing is the first But also street signs, graffiti, Writing is ubiquitous. information technology and candy wrappers. It is in books… And we hardly notice it anymore. 9

Writing is so ubiquitous, it disappears . It is in books 10

3 Device Sizes: tabs, pads and boards ~100 tabs ~10 pads ~1 board 19

Tabs Uses: Size: doors open only to the right badge • wearer, rooms greet people by name, • Location: telephone calls can be automatically • forwarded to wherever the recipient may be, • receptionists actually know where people are, ~100 Number: computer terminals retrieve the • preferences of whoever is sitting at them, and • appointment diaries write themselves. 20

tabs” of 2018? What are the “ ta Size: Location: ~100 Number: 21

Pads Size: Location: Number: ~10 “Pads differ from conventional portable computers in one crucial way. Whereas portable computers go everywhere with their owners, the pad that must be carried from place to place is a failure . Pads are intended to be "scrap computers" (analogous to scrap paper) that can be grabbed and used anywhere; they have no individualized identity or importance.” 22

What are the “ pad ads ” of 2018? Size: Location: Number: ~10 “The pad that must be carried from place to place is a failure. Pads can be grabbed and used anywhere; they have no individualized identity or importance.” 23

Boards Size: Uses: in the home, video screens and bulletin boards; in the office, bulletin boards, Location: whiteboards or flip charts. Number: ~1 24

What are the “ boa oards ” of 2018? Size: Location: Number: ~1 25

How does si size and location correspond to the eeds of people? ab abilities ilities an and need 26

Summary of Mark Weiser’s Predictions Many displays throughout the home and office Devices range in size and location ~1 board, ~10 pads, ~100 tabs Devices will disappear the way writing disappears And becomes an effortless part of our lives. 27

Evaluating Mark Weiser’s Vision 45

In what ways is this true today? “The most profound technologies are those that disappear . They weave themselves into the fabric of everyday life until they are indistinguishable from it.” 46
