Introduction

• A haptic interface is a force reflecting device
  which allows a user to touch, feel, manipulate,
  create, and/or alter simulated three-dimensional
  objects in a virtual environment
• Types
• Tactile
• Kinesthetic

Tactile Interfaces

• Sense of contact
• heat, cold, pain, pressure

4
Kinesthetic Interfaces

• Provide force feedback to the user

5
Kinesthetic Interfaces (cont.)

• Track the movement of the user's body and the
  forces he exerts
• Identify the effect objects of the VE
• Exerts realistic forces and torques which are
  felt by the user
