HAPTIC TECHNOLOGY

PRAVEEN KUMAR- BY

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

INTRODUCTION

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.

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.

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.

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.

FUTURE VISIONCan Touch be distributed over space and time, recorded and broadcasted like streaming data?

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.
