This is abt HAPTIC TECHNOLOGY You can know abt this technology simply by this PPT Thanking you LAKSHMI NARAYANA V.BALUSU

1. Haptics
‘Touch the virtual’
Presented By:1

2. ‘Haptics’ is derived from the Greek word ‘haptikos’
which means-”being able to come into contact ”

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

5. The real world
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

6. Basic idea
Haptics, is the technology of adding the
sensation of touch and feeling to computers.
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.

7. The Technology
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
7

8. Tactile feedback
Refers to the sensations felt by the skin.
It allows the user to feel things such as the
texture of surfaces, temperature and
vibration.
8

9. Force feedback
It reproduces the directional forces that
can result from solid boundaries.
E.g. the weight of virtual objects, inertia,
etc.

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

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

This device fits over the user's entire hand
like an exoskeleton and adds resistive force
feedback to each finger

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