  1. What Is Haptics?  ‘Haptics’ is derived from the Greek word ‘haptikos’ which means – ‘being able to come into contact’.  Haptics is the science of applying touch (tactile) sensation and control to interact with computer applications.  Haptics refers to sensing and manipulation throgh touch.
  2. Haptics Technology  Haptic technology is a technology which takes advantage of the sense of touch by applying forces, vibrations, or motions to the user.  A haptic device gives people a sense of touch with computer-generated environments, so that when virtual objects are touched, they seem real and tangible.
  3. HAPTIC DEVICES Virtual reality/ Telerobotics based devices Feedback devices
  4. Types of haptic devices  Exo skeletons and stationary devices  Gloves and wearable devices  Point source and specific task devices  Locomotion interface  Tactile feedback devices  Force feedback devices
  5. Exo skeletons  Current haptic devices that are classified as exoskeletons are large & Immoble systems that the user must attach him- or herself to. Gloves & wearable devices  The user can move naturally without being weighted down by a large exoskeleton or immobile device
  6. Point sources&specific task devices  An interesting application of haptic feedback is in the form of full body force feedback called locomotion interfaces.  movement of force restriction devices in a confined space,simulate unrestrained human mobility such as walking and running for virtual reality. Locomotion interface  This is a class of devices that are very specialized for performing a particular given task  Specialized for performing a particular task.
  7. Haptic devices 1.Phantom • providing a 3D touch to the virtual objects • when the user move his finger, then he could really feel the shape and size of the virtual 3D object that has been already programmed. • It works monitoring the position of user fingertip or hand by optical encoder
  8. 2.Cyber grasp • The Cyber Grasp system fits over the user's entire hand like an exoskeleton and adds resistive force feedback to each finger • Adapted to different size of the fingers • Located on the back of the hand
  9. Haptics Feedback  Haptics is implemented through different type of interactions with a haptic device communicating with the computer. These interactions can be categorized into the different types of touch sensations a user can receive: 1)Tactile Feedback 2)Force Feedback
  10. Tactile Feedback  Refers to the sensations felt by the skin.  It allows the user to feel things such as the texture of surfaces, temperature and vibration.
  11. Force Feedback  Force feedback devices give us some feedback as a type of force during the interaction. There are many types of devices: game pads, joysticks, gloves, steering wheels, trackball, mice, etc.  It reproduces the directional forces that can result from solid boundaries. E.g. the weight of virtual objects, inertia, etc.
  12. Uses  Simulators  Video games  Mobile technology  Robotics  Medicine  Research The application of this technology is used in many fields such as:
  13. Teleoperators and simulators  Teleoperators are remote controlled robotic tools. When robotic tool comes in contact with the object of interest, then “force feedbacks” are sent back. This haptic technology is generally used when a scientist wants to investigate a dangerous substance e.g. Radioactive material. A robotic tool is sent instead and a scientist will get feedback through force.  Simulations are commonly used to give a feel of the real event to a person.  Haptic simulators are currently used in medical simulators and flight simulators for pilot training.
  14. Video Games  Video games such as car racing games, using peripherals such as joystics and steering wheels, create motion, give you a virtual simulation of driving a car. This is done through the use of haptic technology
  15. Medicine  Haptic teleoperators are used by surgeons to carry out operations with the least trauma and better outcomes for the patient  Telepresence surgery Surgeons perform operations remotely  “spider-sense” bodysuit, equipped with ultrasonic sensors and haptic feedback systems, which alerts the wearer of incoming threats allowing them to respond to attackers even when blindfolded
  16. Mobile Consumer Technologies  Haptic feed back (response) is becoming common in mobile phones. It enables users to feel clicks, vibrations and other tactile input.  Samsung, dubbed the Anycall Haptic, features a large touch-screen display just like the iPhone but provides the user with 22 kinds of touch sensations.
  17. Military & Robotics  Military Training in virtual environment.  Haptic technology is also widely used in tele operation or tele robotics RoboticsMilitary
  18. Future scope Holographic interaction The feedback allows user to interaction the feedback allows the user to ineract with a hologram and actually receive tactile response using acoustic radiation presure Medical applications Use of a central workstation from which surgeons would perform operations in various locations,with machine set up & patient preparation performed by local nursing staff Textile industry  User could study & feel the texture and quality of material during the sale of cloth through internet
