2. What is haptics???
2
HAPTICS-a technology that adds sense of touch to virtual
environment.
haptics interfaces allow the user to feel as well as to see virtual
objects on a computer, and so we can give an illusion of touching
surfaces, shaping virtual clay or moving objects around.

The phantom provides
single point, 3D force-feedback
to the user by stylus
attached to a moveable
arm.

CYBER GLOBE
Cyber Glove can sense the
postion and movement of
the fingers and wrist.
CYBER GRASP:
The Cyber Grasp is a full hand
force-feedback exo skeleton device.
9. Medical Training Applications
9
Such training
systems make use of
phantom's force display
capabilities to let medical
trainies experience.
10. Collision Detection
10
Collision detection is a
fundamental problem in
computer animation,
physically based modeling,
geometric modeling and
robotics.
12. Tactile Slip Display
12
Human fingers are able
to manipulate delicate objects
without either dropping and breaking
them.
13. Other Applications
13
MOBILE PHONES
samsung and motorola
supports haptics technology.
CARS
BMW 7 series makes use of
haptics technology.
14. Future Enhancements
14
The Virtual Braille
Display (VBD)
was created to investigate
the possibility of using the
lateral skin stretch
technology.
15. Haptic Torch for the Blind
15
The device, housed in a
torch, detects the distance
to objects.
16. More future vision

1.Holographic Interaction
The feedback allows the user to interact
with a hologram and actually receive
tactile response using acoustic radiation
pressure
2.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
3. Textile Industry
User could study and feel the texture and
quality of materail during the sale of cloth
through internet
17. Conclusion
17
The next important step towards
realistically simulated environments that
have been envisioned by science fiction
authors.
Continued implementation of tactile
devices to aid people with disabilities will
advance further
Future generations of mobile devices and
game console accessories will implement
more haptic feedback
Still embryonic when compared to full
fledged VR simulations
