ppt on haptic technology

1. HAPTIC TECHNOLOGY

2. INTRODUCTON
 Haptic technology refers to technology that relates the
user with a virtual environment via the sense of touch by
applying forces ,vibration and or motion to the user
 It provides link between real and imaginary world
 When virtual objects are touched ,they seems real and
tangible

3. HAPTICS……??????
 Derived from greek word
‘haptikos’ meaning “able
to come in contact with “
 Haptics = Touch =
Connection
 Touch is the most
proficient senses ,the only
one capable of
simultaneous input and
output

4. WORKING OF HAPTIC SYSTEM:
BASIC SYSTEM CONFIGURATION

5. HAPTIC INFORMATION:
TACTILE INFORMATION
Refers to the information required by the sensors connected to
the body.
Kinematic information:
Refers to information acquired by the sensors in the joint .

6. CREATION OF VIRTUAL
ENVIRONMENT:
 VIRTUAL REALITY
Allow user to interact with a computer stimulated environment
 STIMULATED ENVIRONMENT
Stimulated environment can be stimulation of real and imaginary
world
 WIDE APPLICATION
can have wide application by amalgamation of different technologies
such as IOT

7. HAPTIC DEVICES
 VIRTUAL REALITY BASED DEVICES:
1.Exoskeleton and Stationary devices
2.Gloves and Wearable devices
 FEEDBACK DEVICES
1.Force feedback devices
2.Tactile feedback devices

8. COMMONLY USED HAPTIC DEVICES
PHANTOM
1.Provides 3d touch to the virtual objects
2.provides 6 D.O.F
3.When the user moves his finger, then he
could really feel the shape and size of the
virtual 3d objects that has been already programmed
4.virual 3dimension space in which the phantom operates
is called haptic scene

9. PHANTOM DEVICE:

10. CYBER GRASP:
1.The cyber grasp system fits over the entire hand like an
exoskeleton and add resistive
force feedback to each finger
2.Allow 4 d.o.f for each finger
3.can feel shape and size of computer
generated 3d objects

11. APPLICATIONS OF HAPTICS:
 MEDICAL APPLICATION
1.Telepresence operation by remote surgery
2.virtual medical training
3.3d holographic
 MILITARY APPLICATION
1.Virtual military training .This type of training will reduce
excessive cost

12. Contd…..
 Assistive technology for blind and visually
impaired
 Entertainment
gaming experience
 Museum Display
 Holographic interaction

13. LIMITATION
 High cost
 Large weight and size of haptic devices
 Devices can exert force with limited magnitude
and not equally well in all direction

14. CONCLUSION
 Continued implementation of tactile devices to aid people
with disabilities will advance further.
 Currently limited to consumer
 Future generation of mobile devices and game console
accessories will implement more haptic feedback
 Will bring revolutionary change in the world of
telecommunication
