3.  Haptics is the science of applying tactile
sensation & control to interact with computer
applications.
 Illusion of touching and manipulating a real
physical objects.
 Sensation of touch is the brain’s most effective
learning mechanism.
abstract

4. • Haptic is the term derived from the Greek word
“Haptikos” which means ‘sense of touch’.
• Haptic refers to sensing and manipulation
through touch.
• It permit users to sense and manipulate 3-D
virtual objects with respect to shape ,weight ,
surface and temperature.
• Haptic technology does for the sense of touch
what computer graphics does for vision.
introduction

5.  FIRST GENERATION – Use of electromagnetic technologies.
 SECOND GENERATION –touch-coordinate specific responses
allowing the haptic effects to be localized to the position on screen.
 THIRD GENERATION – delivers both touch-coordinate specific
responses and customizable haptic effects.
 FOURTH GENERATION – pressure sensitivity. [R1]

8. • Tactile information :- refers to the sensation felt
by the skin. [R5]
•Kinesthetic information :- refers to information
acquired through the sensations originating in
muscles, tendons and joints. [R5]

10. applications
• Medical applications.
• Video games.
• Mobile consumer technologies.
• Assistive technology for the blind and visually
impaired.

11. advantages
 Working time is reduced.
 Communication is centered through touch and the
digital world can behave like the real world.
 Increase confidence in medical field.

12. limitations
 High cost involved.
 Large weight and size of haptic device.
 Haptic interfaces can only exert forces with limited
magnitude and not equally well in all directions.
The precision of touch requires a lot of advance design.
 Bandwidth limitation is a major problem .

13. This technology has proved that virtual objects can also
be touched ,felt and controlled.
 This technology make the future world as a sensible one
 This technology brings us one step closer to virtual
world.
