Haptics is a technology that uses haptic devices to allow users to touch and feel virtual objects. By providing tactile and force feedback, haptic devices can simulate interactions with computer-generated environments and remotely touch objects. This enhances the sense of presence in virtual reality and telepresence by extending the sense of touch. Haptics has applications in gaming, virtual reality, virtual surgery, military training, robot control, and more. Continued development aims to make haptic devices smaller, lighter and easier to use.

3. • A haptic device gives people a sense of touch with
computer-generated environments, so that when
virtual objects are touched, they seem real and
tangible.
• Understanding and enabling a compelling
experience of Presence not limited to "being there",
but extended to "being in touch" with remote or virtual
surroundings.

4. • User should be able to touch the virtual object
and feel a response from it.
• In order to complete the imitation of the real world
one should be able to interact with the
environment and get a feedback.
• This feedback is called Haptic Feedback

5. • Human Haptics
• Machine Haptics
• Computer Haptics

6. • Virtual reality is a form of human-computer
interaction providing a virtual environment that one
can explore through direct interaction with our
senses.
• It’s only an imitation of the real world.

7. Haptics is implemented through different type of
interactions with a haptic device communicating
with the computer. These interactions can be
categorized into the different types of touch
sensations a user can receive:
• Tactile feedback
• Force feedback

11. It allows human to touch, feel and manipulate
3-D objects in virtual environments.

12. •Common interface devices like mouse and joystick
are only input devices. No feedback.
•Haptic devices are input-output devices.

22. •Haptic devices must be smaller so that they are
lighter, simpler and easier to use.
•Large potential for applications in critical fields as
well as for leisurely pleasures.
•The next important step towards realistically
simulated environments that have been
envisioned by science fiction authors.
