3. WHAT IS HCI ?
human beings.
• Human-computer interaction (HCI) is a field of
study concerned with how people interact with
computers and other digital technologies.
• It involves the design, evaluation, and
implementation of user interfaces and systems that
enable effective and efficient interaction between
humans and machines.
7. FACTORS OF HCI
• Organization Factors :- Training, job design, politics, work organization.
• Environmental Factors:- Health, Heating, Ventilation, Lighting.
• The User:- Cognitive process, Satisfaction, Experience.
• Comfort Factors:- Equipment, Seating, Layout.
• User Interface:-Input devices, Output devices, Use of color, Icons.
• Task factors:-Easy, Complex, Task allocation, Skills.
• Constraints:-Cost, Timescales, Budgets, Equipment.
• System Functionality:- Hardware, Software, Application.
• Productivity Factors:-Increase output, Increase quality, Decrease costs.

14. GOALS OF HCI
Safety – of users, of data
Utility –services are provided
Effectiveness- easy to find and use services
Efficiency- how quickly users can work
Usability- ease of learning and use
Appeal- how well user like the interface
From first impression to long-term satisfaction
23. Regional Analysis
In the Asia-Pacific area, mobile devices like smartphones &
tablets are increasingly the main way to access digital
systems, similar to other regions. As the region’s mobile
market expands, businesses that provide mobile-friendly
Human-Computer Interaction solutions are likely to be in high
demand.
24. •Europe to Have Admirable Growth in Human
Computer Interaction Market
Some of the most significant technology centres in the world
are located in Europe, including cities like London, Paris,
Berlin, & Amsterdam. These cities are in fact home to a large
number of cutting-edge start-ups and well-established
technology firms, which support the area’s robust
technological infrastructure and support the creation of fresh
Human-Computer Interaction products.

1942 and lived a good portion of his life
without a disability.
• Dr .hawking was diagnosed with
Amyotrophic lateral Sclerosis(ALS).
• As ALS progresses ,the degeneration of
motor neurons in the brain interface with
messages to muscles in the body.
• Dr. Hawking used assistive technology to
compensate for mobility and speech
difficulties. He used a thumb switch and a
blink-switch attached to his glasses to
control his computer.

27. Failure of :Google car “the waymo”
• Accidents: Despite rigorous testing and safety measures, self-driving cars
developed by Google have been involved in a few accidents. However accidents
were mostly caused by human error rather than a failure of the technology itself.
• Technical limitations:Self-driving cars face challenges in handling
complex and unpredictable driving scenarios, such as adverse weather conditions
or unexpected behavior from pedestrians or other vehicles.
• Public perception and acceptance: Many people still have
reservations and concerns about the safety and reliability of self-driving cars.
Building public trust and acceptance for this technology has been a challenge, and
incidents involving self-driving cars have sometimes fueled skepticism and fear.
28. “It's important to note that failures
and challenges are part of the
innovation process, and the
setbacks encountered by the Google
Cars project have contributed to the
ongoing development and
refinement of self-driving
technology.”
29. HCI IN INDIAN SCENERIO
•Global Innovation Index 2023 India Rank India is ranked 40th position out of 132 in
the Global Innovation Index (GII) 2023 rankings released by World Intellectual
Property Organization (WIPO).
30. •Launch year: 2015
Digital India is a campaign launched by the Government of India to
ensure that the Government's services are made available to
citizens electronically through improved online infrastructure and
by increasing Internet connectivity or making the country digitally
empowered in the field of technology.

36. CONCLUSION
Human –Computer Interaction (HCI) is a field of study that deals with the design,
development, and evaluation of computer system that people interact with .The
ultimate goal of HCI is to create user-friendly and efficient computer systems that
can enhance human productivity and satisfaction.
HCI has evolved over the years from being focused on physical input devices such
as keyboards and mice to include touchscreens,voice recognition, and other
natural user interfaces. Additionally ,HCI has become increasingly interdisciplinary,
incorporating knowledge and research from psychology .sociology ,anthropology ,
and other fields to inform the design of computer systems that meet human needs
and preferences.
Overall, the field of HCI is essential in ensuring that technology is designed and
implemented in a way that benefits humans and enhances their lives.
