 HAPTIC TECHONOLOGY

In our paper we have discussed the basic concepts behind haptic along with the haptic devices and how these devices are interacted to produce sense of touch and force feedback mechanisms. Also the implementation of this mechanism by means of haptic rendering and contact detection were discussed. We mainly focus on Application of Haptic Technology in Surgical Simulation and Medical Training'. Further we explained the storage and retrieval of haptic data while working with haptic devices. Also the necessity of haptic data compression is illustrated.

Haptic Technology

Introduction: Haptic, is the term derived from the Greek word, haptesthai, which means ‘to touch’. Haptic is defined as the “science of applying tactile sensation to human interaction with computers”. It enables a manual interaction with real, virtual and remote environment. Haptic permits users to sense (“feel”) and manipulate three-dimensional virtual objects with respect to such features as shape, weight, surface textures, and temperature.

A Haptic Device is one that involves physical contact between the computer and the user. By using Haptic devices, the user can not only feed information to the computer but can receive information from the computer in the form of a felt sensation on some part of the body. This is referred to as a Haptic interface.

In our paper we explain the basic concepts of ‘Haptic Technology and its Application in Surgical Simulation and Medical Training'.

Haptic Devices: Force feedback is the area of haptics that deals with devices that interact with the muscles and tendons that give the human a sensation of a force being applied-hardware and software that stimulates humans' sense of touch and feel through tactile vibrations or force feedback. These devices mainly consist of robotic manipulators that push back against a user with the forces that correspond to the environment that the virtual effector's is in. Tactile feedback makes use of devices that interact with the nerve endings in the skin to indicate heat, pressure, and texture. These devices typically have been used to indicate whether or not the user is in contact with a virtual object.
