HAPTIC TECHNOLOGY

INTRODUCTION

  • Haptic technology, or haptics, is a tactile feedback technology that takes advantage of our sense of touch by applying forces, vibrations, and/or motions to the user through a device. The word is derived from the Greek word “haptein” meaning “to fasten.”
    • Interfaces: established out of field of tele-operation
    • Telerobotic applications
slide3

Why Haptics ?

  • Touch is the first sense to develop when we are born and the last sense used before death.
  • It is 20 times faster than vision.
  • No need of continuous user interaction with the mobile device.
  • Need not be a map expert to understand the way haptic feedback works.
  • Humans are highly sensitive to vibrations up to1000Hz (most sensitive at 250Hz)
  • The user can interact with the real environment and people around rather than the mobile device.
slide4

Haptics System includes:

  • Immersion haptics system includes:
    • Sensor(s),
    • Actuator (motor) control circuitry,
    • One or more actuators that either vibrate or exert force,
    • Real-time algorithms (actuator control software, which we call a “player”) and a haptic effect library,
    • Application programming interface (API), and often a haptic effect authoring tool.

APPLICATIONS

  • For The Visually Impaired
  • Gaming Application
    • Casino gaming experience
    • Gaming Wheel
    • Game Pad
  • Automotive
  • Consumer electronics
    • Cue radio
  • Virtual education
  • Medical training applications

ADVANTAGES

  • Communication is centered through touch and the digital world can behave like the real world.
  • Working time is reduced since objects can be captured, manipulated, modified and rescaled digitally.
  • Medical field simulators allow would be surgeons to practice digitally, gaining confidence in the procedure before working on breathing patients.
  • With haptic hardware and software, the designer can maneuver the part and feel the result, as if he/she were handling the physical object.
slide11

limitations

  • The precision of touch requires a lot of advance design.  With only a sense of touch, haptic interfaces cannot deliver warnings.
  • Haptics applications can be extremely complex, requiring highly specialized hardware and considerable processing power.
  • The complexity also means that many haptics projects rely on fixed installations of equipment and are not easily portable.
  • Debugging issues—these are complicated since they involve real-time data analysis.
  • Costs for haptics projects can be considerably high.
slide12
FUTURE VISIONCan Touch be distributed over space and time, recorded and broadcasted like streaming data?
conclusion
CONCLUSION

1) Future for online computing and e-commerce.

2) Enhance the shopper experience and help online shopper to feel the merchandise without leave their home.

3) Because of the increasing applications of haptics, the cost of the haptic devices will drop in future.
