2.  In 1975 Bill Gates and Paul Allen
started up a company called
Microsoft in which they had a
mission to put a computer in every
home.
 In 1980 Steve Bahlmer joined the
team and they were brought a
project code from IBM called chess.
The three of them then began
development of an operating system
(OS) that would manage the
hardware and also allow the
software to work with the computer
hardware.
 The development of the Microsoft
Disk Operating System (MS-DOS)
was finally completed in 1981 and
IBM shipped the first systems
running the new OS (Microsoft,
2015).
 Even though MS-DOS was still
difficult for many to use it still
allowed for people to interact with
computers in a whole new way and
really started a revolution in
personal computing.
1975-1981

3.  Once the Military decommissioned the ARPANET, the public use of the
internet was granted. When the World Wide Web became publically
available it changed the way that humans interacted with their
computers.
 Berners-Lee developed the first web browser software called fittingly and
utilized a server called CERN to demonstrate the use of the internet
which led to the launch (Bryant, 2011). Once the internet launched in
1991 their was a post made on a newsgroup page explaining how to
download and operate within the internet for all of the new users. Though
this release didn’t change everything about computing on the first day, it
definitely made a massive difference. Users were able to share, download,
and view content from anywhere they had a computer and internet
connection.
1991

4.  The first release of Google’s Android
Operating System (OS) was in 2008
which changed the mobile market and
the way that we interacted with our
cellular devices by creating an
interactive phone, computer, and
camera all in a single small device we
carried everywhere.
 Android released to consumers on the T-
Mobile HTC G1. The device didn’t have
anything spectacular when it came to
hardware but it they created an open
source operating system which started a
revolution in the mobile market (Verge
Staff, 2011).
 Android got a lot of things right
when it came to their user interface,
such as the notification window, the
use of widgets, and the overall look
and feel and they did this on their
first release. Though some changes
have occurred and their has been
much improvement to existing
features and added features to the
OS, they did an excellent job when
it came to the user experience.
2008

5.  What/How - Personal computing changed the way we interacted with computers and are
commonly referred to as PC’s. The PC is a hardware/software environment that works
together to allow for complex tasks to be completed and programs to run. These computers
use a number of ways to store data such as a DVDRW, CDRW, thumb drive, external hard
drive, SD card, and the internal storage. CD and DVD roms are still used but not nearly
like they used to be since personal computers and the way we store our data is rapidly
changing, using smaller and thinner devices with larger storage capacities and the ability
to install programs and share information quickly straight from the internet or by using a
USB thumb drive there is less of a need for the CD and DVD.
 Where/When – The personal computer was a home use computer that would allow people
to be able to use them not only at home but in the office, and also allow for people to use
them for entertainment. The PC allowed for computing power to be used whenever the
user wanted to and wherever they wanted to use it with the Laptop or Tablet PC.
 Who/Why – Anyone who wants to use a PC can and almost everyone does. It would be
easier to answer the question if you asked who does not use a PC. There are several
reasons to use a personal computer such as graphic design, web browsing, creating
numerous types of documents, online shopping, watching videos, video games, and the list
goes on and on.
Interaction Paradigm

6.  What/How – Mobile computing devices have a wide variety of products associated with
this category such as Laptops, Tablets, Smartphones, MP3 Players, Mobile GPS
navigation, and several other devices. The tablet computer incorporates a touchscreen for
its main I/O interface and can have a keyboard/mouse added through their USB ports
allowing for more functionality. Laptops come with keyboards attached with an embedded
touch mouse and have a wide range of sizes. These devices are portable because they use
batteries to power their hardware allowing for multiple on the go uses.
 Where/When – Like the name says, they are Mobile. This means that people can take
these devices with them and conduct computer function anywhere they want and at
anytime. With this functionality you can take the device anywhere, and they can use
location-based mobile services (LMS) allowing for a wide variety or other services such as
location based ads, GPS navigation built-in to the device, and several other services that
are based on their mobility.
 Who/Why – Just like personal computing its easier to ask who doesn’t use a mobile
computing device, they have become part of most peoples daily activities and are carried
in peoples pockets.
Interaction Paradigm

7.  Human computer interaction (HCI) is the usability,
functionality, and portability of computers. It is the study of
how humans interact with computers physically and mentally.
HCI is useful in the development of software because we need
to build upon the understanding of how it will best be
interacted with and how the human component can solve their
problem using the software program or operating system and
to incorporate the use of the software into new devices that
allow fore more portability and more/new integrations of
devices into our physical environment.
