Haptic technology, also known as force-feedback technology, uses the sense of touch through receptors in the skin, muscles, and joints. There are two groups of touch receptors: kinesthetic receptors in the tendons, muscles, and joints and tactile receptors in the dermis and epidermis. Haptic devices can provide haptic feedback and be used for medical training applications to increase accuracy, for stroke patients to interact with virtual worlds through touch, and to measure forces during minimally invasive surgery.

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

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.
