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.

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.

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

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
