Haptic technology provides tactile feedback through devices that allow users to touch and feel virtual objects. It works by applying forces, vibrations or motions to the user through input/output devices like data gloves. This gives users the sense of touch when interacting with computer-generated environments. Common haptic devices include Phantom, which provides 3D touch feedback of virtual objects, and Cyber Grasp, which fits over the hand and provides force feedback to each finger. Haptics have applications in virtual reality, medicine, video games, mobile devices, arts and robotics. The future may see holographic interaction and remote surgery using haptics.

2. What is it…?
 Haptic technology is a tactile feedback technology
which takes advantage of the sense of touch by
applying forces, vibrations, or motions to the user.
 Haptics (pronounced HAP-tiks) is the science of
applying touch (tactile) sensation and control to
interaction with computer applications.
 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.

3.  By using special input/output devices (joysticks, data
gloves, or other devices), users can receive feedback from
computer applications in the form of felt sensations in the
hand or other parts of the body.

4. • 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.

5. Continued…
 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: Refers to the sensations felt by the
skin. It allows the user to feel things such as the
texture of surfaces, temperature and vibration.
 Force Feedback: It reproduces the directional forces
that can result from solid boundaries. E.g. the weight
of virtual objects, inertia, etc.

11.  Common interface devices like mouse and joystick
are only input devices. No feedback.
 Haptic devices are input-output devices where
output is in the form of sensation .

12. COMMONLY USED HAPTIC DEVICES
1.PHANTOM
 Provides a 3D touch to the virtual objects.
When the user move his finger, then he could really
feel the shape and size of the virtual 3D object that has
been already programmed.

13. 2.CYBER GRASP
 The Cyber Grasp system fits over the
users entire hand like an exoskeleton
and adds resistive force feedback to
each finger .
 Adapted to different size of the
fingers .
Located on the back of the hand .

15. MEDICAL APPLICATIONS
 Sense of touch is crucial for medical training.
 Various haptic interfaces for medical
simulation may prove especially useful for
training.

16. COMPUTER AND VIDEO GAMES
 Haptic feedback is commonly used in arcade games,
especially racing video games.
 Disney Research, Pittsburg (DRP) has shown off a
revolutionary technology called ‘Surround Haptics’
that can bring real life experience in video gaming
and film watching.

17. MOBILE DEVICES
Tactile haptic feedback is becoming
common in cellular devices.
VIRTUAL REALITY
Haptics are gaining widespread
acceptance as a key part of virtual
reality systems.

18. ARTS AND DESIGN
Haptics is used in virtual arts, such as
sound synthesis or graphic design and
animation.
ROBOTICS-
Haptic technology is also widely used in
teleoperation, or telerobotics.

20. FUTURE VISION
HOLOGRAPHIC INTERACTION
The feedback allows the user to interact with a hologram and
actually receive tactile response using radiation pressure.
MEDICAL APPLICATION
Use of a central workstation from which surgeons would perform
operations in various locations; with machine setup and patient
preparation performed by local nursing staff.
TEXTILE INDUSTRY
 User could study and feel the texture and quality of material
during the sale of cloth through internet.
