3. ‘HAPTIC’
 HAPTIC :having to do with sense of touch.
 HAPTIC :also known as force-feedback
technology
 Why use touch?
1. natural
2. Fast
3. Good for building up mental picture of 3D
objects.
4. Exploration.

4. GROUPS OF RECEPTORS
Sense of touch has 2 groups of receptors
 Kinesthetic
 Tactile

5. Location of Receptors
 Kinesthetic –
tendons, muscles
and articular joints
 Tactile- dermis &
epidermis

6. Architecture for Haptic
feedback

7. Haptic Devices

8. Medical training applications

9. Prostate Cancer
 Improves
Brachytheraphy by
increasing seed
distribution
accuracy.

10. Stroke Patients
Patients interact with
virtual worlds by feel.

11. Minimally Invasive surgery
 Measures forces
and torques.
 Determines Dof
forces.

12. Immersion:
 Mobiles –more
useful.
 Games –more
electrifying.
 Automobile controls-
more intuitive.
 Medical training
simulators-more
effective.

14. Torch for BLIND

15. Virtual Brailee Display: (vdb)

16. CONCLUSION:
 Future for online computing & E-
commerce.
 Part of a Person’s normal computer
interaction.
