Calculating devices in antiquity
• The abacus (plural abaci or abacuses), also called a counting
frame, is a calculating tool which has been used since ancient
times.
• It was the first calculating device that improved about 5000
years ago by the Chinese educationists.
• It was used in the ancient Near East, Europe, China, and Russia,
centuries before the adoption of the Hindu-Arabic numeral
system.
Konrad Zuse (1910-1995)
Invented the world’s first programmable computer (in
1941)
This remained the only working computer in Europe
up to 1951
ENIAC (~1946)
• First electronic numerical integrator and computer
in the US.
• Construction contract was signed in 1943.
• The first programmers of the ENIAC were six
women (“Refrigerator Ladies”).
Memex (1945)
Vannevar Bush was an Memex is a conceptual
American engineer, inventor and data storage and retrieval
science administrator, who system outlined by
during World War II headed the Vannevar Bush.
U.S. Office of Scientific Research and
Development (OSRD), through which
almost all wartime military R&D was
carried out, including important
developments in radar and the
initiation and early administration of
the Manhattan Project.
Memex (1945) cont.
“wholly new forms of encyclopedias will appear,
ready made with a mesh of associative trails running
through them…”
Memex (1945) cont.
“If the user wishes to consult a certain book, he
taps its code on the keyboard…”
“Frequently-used codes are mnemonic, so that
he seldom consults his code book;”
“He can add marginal notes and comments …
even … by a stylus scheme”
“All this is conventional…”
SketchPad by Ivan Sutherland
At MIT (1963)

SketchPad by Ivan Sutherland
(cont.)
• Direct manipulation of objects
• SketchPad paved the way for the Graphical User
Interface
• Sutherland’s PhD thesis also defined the terms
“objects” and “instance”.
• SketchPad is the first object-oriented programming
system.

Stanford (1963)
Nothing eventful happened in
the next 10 years…
Xerox Alto (1973)
It is a computer designed
from its inception to
support an operating
system based on a
graphical user interface,
later using the desktop
metaphor.
Xerox Alto (1973) (cont.)
VisiCalc (1979)
VisiCalc was the Killer App for
Personal Computers
• Turned the microcomputer from a hobby for nerds into
a serious thing.
• Because of it, IBM introduced the IBM PC.
• 2 years later suddenly, small and large
business bought computers
With the emergence of personal
computing in the late 1970s, everyone
became a potential computer user…
… but computer users still had to deal
with arcane commands and system
dialogs

HCI Disciplines
"HCI is concerned with understanding the influence
technology has on how people think, value, feel, and relate
and using this understanding to inform technology design."
Wright & McCarthy (2008)
HCI’s impact on society
We can now use computers as an
every-moment- partner
Less and less training is required for most
application and devices
Some examples
- Touch screen: direct interaction with
objects
- Voice control: for some people the
only way to interact with
computers
HCI’s impact on culture
Smartphones have changed how we
spend our "empty times": should we
read the news? answer emails? chat
with friends? play "2 Dots"? should
we just be bored?
Social Media have influenced how we
stay in touch with each other and how
find new friends and lovers.
Games, more than entertainment, can
be used as social and even
productive tools.
HCI’s impact on economy
Massive increase in productivity
HCI found how to speed up input and reduce its complexity
People can perform tasks faster than they used to
Reduced need for training
More people can use technology than ever before
What now???

Invented
by Charles “The idea for the technology came to Crump in 1988
when he decided to make a toy frog for his young
Hull daughter using a glue gun loaded with a mixture of
polyethylene and candle wax. He thought of creating
the shape layer by layer and of a way to automate the
process. In April 1992, Stratasys sold its first product,
the 3D Modeler.”

Activity/Assignment
Activity (10 minutes)
How would you change this thing?
Make sure your idea is innovative!
Sketch out your design on a piece of paper
and write your names on it
(this time we will collect it :) )
Reflection
What did you come up with?
What were the challenges?
Thank You
