‘Haptics’ is derived from the Greek word ‘haptikos’ which
means – ‘being able to come into contact’.
Haptics is the science of applying touch (tactile) sensation and
control to interact with computer applications.
bidirectional communication between humans and computers
to include sensory feedback.
Haptics = Touch = Connection
Virtual reality is a form of human-computer interaction
providing a virtual environment that one can explore
through direct interaction with our senses.
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.
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
Refers to the sensations felt by the skin.
It allows the user to feel things such as the texture of
surfaces, temperature and vibration.
It reproduces the directional forces that can result from
E.g. the weight of virtual objects, inertia, etc.
It allows users 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.
