HAPTICS
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.

How it works???
5
There are two types of rendering algorithms:1) geometry dependent force rendering algorithm2) surface property dependent force rendering algorithm
6
.
PHANTOM
7
The phantom provides
single point, 3D force-feedback
to the user by stylus
attached to a moveable
arm.
.
8
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.
Medical Training Applications
9
Such training
systems make use of
phantom's force display
capabilities to let medical
trainies experience.
Collision Detection
10
Collision detection is a
fundamental problem in
computer animation,
physically based modeling,
geometric modeling and
robotics.
Prostrate Cancer
11
This technology is used in branchtherapy treatment.
Tactile Slip Display
12
Human fingers are able
to manipulate delicate objects
without either dropping and breaking
them.
Other Applications
13
MOBILE PHONES
samsung and motorola
supports haptics technology.
CARS
BMW 7 series makes use of
haptics technology.
Future Enhancements
14
The Virtual Braille
Display (VBD)
was created to investigate
the possibility of using the
lateral skin stretch
technology.
Haptic Torch for the Blind
15
The device, housed in a
torch, detects the distance
to objects.
More future vision
16
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
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
