Human Computer Interaction is one of the emerging concept in the field of Computer Science and Engineering. It is a technology that is going to change the way we interact with the computer and so on.....Enjoy viewing the magic of Computer Science and Engineering. Technology in your hands.... _S.Nalaemton

3. HCI involves
• The study
• Planning
• Design
• Uses of interaction between user
and the computer.
Three common interfaces:
• GUI
• VUI
• gUI

4. The History of HCI
The term HCI was popularized by
• Card
• Moran
• Newell
The first book on HCI :
‘The Psychology of Human-Computer
Interaction’ (1983).
The terms’ first known use was in 1975.

5. Yesterday…Today and Tomorrow!!!
Scenario Input Output
Early days • Connecting wires
• Paper tapes
• Punch cards
• Keyboard
• Lights on display
• Paper
• Teletype
Today • Keyboard
• Cursor keys
• Mouse
• Microphone
• Scrolling glass teletype
• Character terminal
• Bit mapped screen
• Audio
Future • Data gloves + suit
• Computer jewellery
• Natural language
• cameras
• Head mounted displays
• Ubiquitous computing
• Autonomous agents
• Multimedia

6. The misfortunes of HCI so far…
Poorly designed Human-Computer Interfaces leads
to many problems. Some of the fatal failures of HCI
include:
• Three Mile Island accident
• Aviation failure
The designs are conceptually fantastic but
unfortunately had undesirable results.

7. Goals of HCI
• Methods for implementing interfaces.
• Techniques for evaluating and comparing interfaces.
• Developing new interfaces and interaction techniques.
• Developing descriptive and predictive models and theories
of interaction.
• Design systems that minimize the barrier between human
mental model and the computer.

8. Applications of HCI
• Intelligent homes
• Intelligent offices
• Driver monitoring
• Intelligent gaming
• E-commerce
• Helping people with
disabilities

12. Multimodal Web Interface
Bharati:
A internet user interface for both language and computer
illiterate people: text, speech, icon.
Bharati Chopra:
Iconic module for the people unable to read/write in their
mother tongue.
Bharati Dhwani:
Speech based module for those who can speak but not
reading/writing ability in their mother tongue.
Bharati Akshar:
Text based module for the user unable to use English.

13. Multimodal Framework of Bharati

14. Helping People with disabilities
•A good application of multimodal systems is to address and assist
disabled people.
•In this system users can interact with machine using voice and head
movements.
•Two modalities are used and both are active continuously: speech and
head movements.
•Speech provides the needed information about the meaning of the
action that must be performed with an object selected by the cursor.
•The head position indicates the coordinates of the cursor on the screen
at the current moment.

15. Natural User Interface
 Advantages
 No training required
 Can be quicker than keyboard entry
 Hands-free
 Can be used by the disabled
 Disadvantages
 Emerging technology – still contains “bugs”
 Difficulty in dealing with homonyms
 Difficult to recognise all the different ways of saying things (and
regional dialects)
 Artificial languages are often more precise
