  3. 3. INTRODUCTION  Haptic Technology, or Haptics, is a tactile feedback technology that takes advantage of a user’s sense of touch by applying forces, vibration and motions to the user.  Derived from Greek word ‘Haptikos’ meaning “Sense of Touch”.  It has been described as “doing for the sense of touch what computer graphics does for vision”.  When virtual objects are touched, they seem real. 3

  7. 7. HAPTIC INFORMATION & RENDERING  Basically the information provide by the system is the combination of Tactile and Kinesthetic information.  The actual process used by the software to perform its calculations is called haptic rendering. 7 Fig.4: Heptic Rendering Architecture[4]

  10. 10. CHALLENGES  The precision of touch requires a lot of advance design.  Large weight, size & high cost involved of haptic devices (especially wearable ones).  Haptic interfaces can only exert forces with limited magnitude and not equally well in all directions.  Haptics projects rely on fixed installations of equipment and are not easily portable.  Haptic-rendering algorithms operate in discrete time whereas users operate in continuous time. 10
  11. 11. CONCLUSION  The next important step towards realistically simulated environments that have been envisioned by science fiction authors.  Haptic Technology enables users to simulate touch and utilize a new input as well as output technology.  Still embryonic when compared to full fledged VR simulations.  Future generations of mobile devices and game console accessories will implement more haptic feedback.  Holographic interaction, Military training, Medical & Textile industry these are the future vision for the haptic technology. 11
