This document discusses human-computer interfaces and interaction. It introduces various types of interfaces that can be used for communication between humans and computers, including command line, graphical user interface, touch screen, virtual reality, voice control, gesture control, and brain control interfaces. The document also covers the advantages and disadvantages of different interfaces, as well as applications and the future of human-computer interaction.

3. • Introduction
o Understand the need to facilitate an effective dialogue
between humans and machines.
o Describe how the user-interface can be designed for
effective communication with the user.
o Explain the need to design systems which are
appropriate to users at all levels and in different
environments.

4. • What is Interface ?
o A point where two objects meet.
o A point where the human can tell the computer what to do.
o A point where the computer displays the requested
information.

5. •Human-Computer Interface
o A human and a computer communicates.
 A human usually has 5 senses:
 Sight.
 Hearing.
 Touch.
 Taste.
 Smell.
o A good interface match would include as many senses
as possible

6. • Graphical User Interface
o Used on computers first by Apple Macintosh, and
afterwards by Microsoft.
o A mouse is used to point and click on icons instead of
typing in a command.
o Dialogue boxes, menus, icons, toolbars etc form the
window on the computer screen.

7. GUI

8. • Touch Screen Interface
o A touch Screen Interface (TUI) is a computer pointing
technology based upon the sense of touch.
o TUI enables not only the sense of touch to innervate
and activate computer based functions

9. • Virtual Reality
 Virtual Reality is applications programs combine the
interfaces already mentioned to give a simulated three
dimensional world of sight, sound, touch and
movement.

10. • Voice Controlled Interface
o A VCI makes human interaction with computers
possible through a voice platform.
o A VCI is the interface to any speech application
controlling a machine by simply talking to it.

11. • Gesture Controlled Interface
o GCI is a technology with the goal of interpreting
human gestures.
o Gesture recognition enables humans to communicate
with the machine and interact naturally without any
mechanical devices.

12. • Brain Computer Interface
o A Brain Computer Interface is a direct Communication
pathway between an enhanced or wired brain and a
computer.
o A BCI is a collaboration between a brain and a device
that enables signals from brain to external activity.

13. • Advantages
 Very easy for the the user to interact with the computer
and maximise the performance.
 No need to learn complex languages.

14. • Disadvantage
o You have to teach user the how to interact.

15. • Applications
 Intelligent homes and offices.
 Driver Monitoring
 Intelligent Games
 E-Commerce
 Helping people with Disabilities

16. • Future of HCI
 HCI is emerging with various other designs concerned
with voice and touch sensory organs.
 Various proposals have been put forward for Emotion
Detection, Gesture Detection.
