• 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.

• 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

• Human Haptics

• Machine Haptics

• Computer Haptics

• 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.

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

.

It allows human to touch, feel and manipulate

3-D objects in virtual environments.

•Common interface devices like mouse and joystick

are only input devices. No feedback.

•Haptic devices are input-output devices.

•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.
