Haptic Technology that can create an experience of touch by applying force,vibrations and motion to the user. Haptic input devices provide the user a tactile feedback.

In virtual reality, medical testing scenarios, games, tactile feedback is used to provide the user a more authentic experience. While user is operating the system the tactile feedback provides him additional information so that error during the interaction with the system can be corrected.

In capacitive keypad there is only visual feedback, user can feel vibration also by using haptic technology.

The vibration motors are two basic varieties: coin and cylinder.

• Sense of touch is crucial for medical instruments.
• Various haptic interface for
  medical simulation may prove
  useful for training.
