4. INTRODUCTION
HCI (human-computer interaction) is the study of how people
interact with computers and to what extent computers are or are
not developed for successful interaction with human beings. HCI
consists of three parts
A)The user
B)The computer
C)The way they work together
5. PARTS OF HCI
USER
COMPUTER
USER AND COMPUTER WORK TOGETHER
6. USER
The person who actually uses a particular product. By "user", we
mean an individual user or a group of users working together. An
appreciation of the way people's sensory systems like sight,
hearing, touch, the way these sensors relay information is vital.
Also, different users form different conceptions or mental models
about their interactions and have different ways of learning and
keeping knowledge.
7. COMPUTER
The machine which inputs the human nature and data to
process it.When we talk about the computer, we're
referring to any technology ranging from desktop
computers, to large scale computer systems. For
example, if we were discussing the design of a Website,
then the Website itself would be referred to as "the
computer". Devices such as mobile phones or VCRs.
8. INTERACTION
There are obvious differences between humans and
machines. HCI attempts to ensure that they both get on
with each other and interact in a successful way. To achieve
a usable system, we need to apply what we know about
humans and computers, and consult with likely users
throughout the design process. The schedule and the
budget are important, and it is vital to find a balance
between what would be ideal for the users and what is
feasible in reality
9. TYPES OF HCI
1)Graphical user interface
2)menu driven interface
3)voice driven interface
4)command line interface
5)touch driven interface
10. GRAPHICAL USER INTERFACE
Graphical user interface is the visual way of
interacting with a computer using items such as
windows, icons, and menus, used by most modern
operating systems. The main pieces of a GUI are a
pointer icon windows menus scroll baars an
intuitive input device. Some common GUIs are the
ones associated with Microsoft Windows
Mac OSX
Chrome
OSGNOME
Android
11. MENU DRIVEN INTERFACE
This type of interface lets you interact with a
computer or device by working your way through
a series of screens or menus. Some examples
include :ATM machines Call center services
Complaint handling mechanism
12. VOICE DRIVEN INTERFACE
A voice-user interface makes spoken human interaction with
computers possible, using speech recognition to understand
spoken commands and answer questions, and typically text to
speech to play a reply. A voice command device is a device
controlled with a voice user interface
Some voice driven interface
(s)Google assistant
Apple siri
Athom Homey
LG Vacuum Cleaner
Mycroft
Samsung Smart TV
13. COMMAND LINE INTERFACE
A command-line interface is a means of interacting
with a computer program where the user issues
commands to the program in the form of
successive lines of text. The program which
handles the interface is called a command-line
interpreter or command-line processor EXAMPLES:
MS DOS
BIOS
CMD
14. TOUCH DRIVEN INTERFACE
Touch driven interface work by your finger
touching the screen. The touching is detected and
translated by the device into instructions. As well
as tapping, the screen can sense swiping and
pinching actions Examples
Cellphones
PDA
ATM machine
15. USES
•For application
design and
engineering.
Computer
Science
•For interactive
products like
mobile phones,
microwave
oven, etc.
Industrial
Design
•For interaction
between
technology and
organization
Sociology
•For application
of theories and
analytical
purpose.
Psychology
16. Ergonomics or
Human Factors
• User-
Equipment
• Design-
Environment
Neuroscience
• Neuroscience
enables us to
build more
accurate and
robust models
of human
cognitive
functions.
Cognitive
Psychology
• Understanding
human
behavior and
mental
processes
Engineering &
Computer
Science
• Faster
machines
• faster systems
• building better
interfaces.
Design
• Interface layout
ADVANTAGES
Teaching the
user
•The user
requires
proper
guidance to
use the
equipment
or else it
will be no
use for
them.
Computer
error
•Computers
are
designed by
humans in
every step.
Any lack of
information
can stop a
computer in
performing
more tasks.
Cheating the
system
•Fake finger
prints can
be used to
bypass
sensor.
•Heavy
makeup can
fool the face
recognition
systems.
Expense
•It is more
expensive
and
complex
than other
methods
Multitasking
•May not be
able to
detect
multiple
users
cooperating
DISADVANTAGES
17. CONCLUSION
Many everyday systems and products seem to be designed
with little regard to usability. This leads to frustration,
wasted time and errors. This list contains examples of
interactive products: mobile phone, computer, personal
organizer, remote control, soft drink machine, coffee
machine, ATM, ticket machine, library information system,
the web, photocopier, watch, printer, stereo, calculator,
videogame etc ¦.How many are actually easy, effortless, and
enjoyable to use?
