3. INTRODUCTION
• Haptics ,is the technology of adding the sensation
of touch tand feeling to the computer
• When virtual abjects are touched they seem real
and tangible

4. HAPTICS....???
• Derived from greek word "haptikos'' meanings ABLE
TO COME INTO CONTACT WITH
• Haptic=Touch=Connection
• Touch is at the core of personal experience
• Of the live sense,touch is the most proficient the
only one capable of simultaenus input and output

5. HISTORY OF HAPTICS
• Scientis used term haptic word to label the subfield of their
studies that addressed human touch-based perception and
manipulation
• By 70s and 80s resarch effrot in a completely different
field,robotics also began to focus on manipulation and
pereciption by touch building a dexterus robotic hand
• In the early 1990s a new usage of the world haptics bagan
to emerge
• The conflence of several emerge technologie made
virtualized haptic,or computer haptics possible

6. HAPTIC INFORMATION
Combination of:
Trafic Information
Refer to the information acquired by
the senser connected by the body
Knesthetic Information
Refer to the information acquired by
the senser in joints

7. TYPE OF HAPTICS DEVICES
VIRTUAL REALITY/ TELEROBTICS BASED DEVICES
• Exoskeletons and stationary objects
• Gloves and wearable devices
• Points source and specific Task device
• Locomotion Interface
FEDBACK DEVICES
• Force Fedback Devices
• Tactile Display Devices

8. PHANTOM CYBER GRASP
HAPTIC DEVICES

9. COMMONLY USED HAPTIC DEVICES
1. PHANTOM
• Providing a 3D touch to the virtual objects
• Provides 6 d.o.f
• When the user move his finger, then he could really
feel the shaped and size of the virtual 3D object
that has been already programmed
• Virtual 3D dimensional space in which the phantom
operates is called haptic sense

11. 2. CYBER GRASP
• The CyberGrasp system fit over the user entire hand like
an ekoskeleton and adds resistive force feedback to
each other finger
• Allow 4 dof for each finger
• Adapted to different size of fingers
• Located on the back of the hand

12. APPLICATION OF HAPTICS
Surgery
Military applications
Arts and Design
Human asistive device
Mobiles
Game and Many more.....

13. LIMITATIONS
• High cost involved
• Large weight and size of haptic device (especially
wearable ones)
• Haptic interfaces can only exert force with limited
magnitudeand not equally well in all directions

14. CONCLUSION
• Continued implementation of tactile devices to aid people
with disabilities will advance further
• Currently limited to consumers
• Future generations of mobile devices and game console
accessories will implement more haptic feedback
