HAPTIC TECHNOLOGY

A PAPER PRESENTED BY,

MOHAMMED MUDASSIR VARDA

INTRODUCTION Derived from Greek  word "HAPTIKOS" meaning

“ABLE TO COME INTO CONTACT WITH”

Haptic Technology or Haptics is a tactile feedback technology which takes the advantage of the sense of touch by applying force.

Haptics is a Technology of adding the sensation of touch and feeling to the Computers.

A Haptic Technology does the sense of touch what a Computer Graphics does for vision.

DEFINITION – HAPTICS Haptics is a Technology of adding the sensation

of touch and feeling to the Computers.

Haptics means both Force feedback and Tactile feedback.

Haptic Sensations combine the interaction of touch in new technology based products.

Haptics allows the user to input information and receive information through the sense of touch.

GENERATION - HAPTICS

First Generation – Use of Electromagnetic Technologies which produce a limited range of sensations.

Second Generation – Touch-Coordinates specific responses allowing the haptic effects to be localized to the position on a screen rather than the whole device.

Third Generation – Delivers both Touch-Coordinate specific responses and customized haptic effects.

Fourth Generation – Pressure Sensitivity, i.e. how hard you press on a flat surface can affect the response.  

HISTORY - HAPTICS Scientists used term haptics to label the subfield

of their studies.

By 70’s and 80’s research efforts in a completely different field, robotics also began to focus on manipulation and perception by touch building a dexterous robotic hand.

In the early 1990s a new usage of the word haptics began to emerge.

The confluence of several emerging technologies made virtualized haptics possible.

WORKING - HAPTICS The working of a haptic sensation requires

Sensors, Actuators, Control Software and Interface.

These Actuators create the force, vibration or texture that the user feels while interacting with the hardware.

The Software Control controls the actuators response based on the data collected from the sensors and the algorithms embedded within it. 

WORKING - HAPTICS

WORKING - HAPTICS

COMPONENTS - HAPTICS Basically the Haptic information provided by the

system is the combination of :

Tactile Sensation

Pressure

Vibration

Temperature

Kinesthetic

Sensation

Position

Orientation

Force

CREATION OF VIRTUAL REALITY

Virtual Reality allows user to interact with a computer-simulated environment.

Users interact with a VR either through input devices or through multimodal devices.

Simulated environment can be either similar or different from reality.

TYPES OF HAPTIC DEVICES

Virtual Reality

TeleRobotics

Taptic Engine 3D Touch

HAPTIC DEVICES

HAPTIC DEVICES

COMMON – HAPTIC DEVICE PHANTOM INTERFACE

It provides a 3D touch to the virtual objects

When the user move his finger, then he could really feel the shape and size of the virtual 3D object that has been already programmed.

The Virtual 3D space in which the phantom operates is called Haptic Sense. 

COMMON – HAPTIC DEVICES

COMMON – HAPTIC DEVICES TAPTIC ENGINE

With the combination of TAP and HAPTIC FEEDBACK taptic engine is a named and was created by Apple for its Technology.

It provides tactile sensations in the form of vibrations.

COMMON – HAPTIC DEVICES 3D TOUCH

3D Touch is a pressure-sensitive display feature introduced by Apple on its 2015 Smartphones.

3D Touch uses capacitive sensors integrated into the smartphone's display to sense three degrees of pressure.

3D Touch is an evolution of its FORCE TOUCH and Multi-Touch capabilities that were introduced in earlier.

3D Touch also provides users with tactile feedback via TAPTIC ENGINE 

APPLICATION – HAPTICS

MEDICAL - Sense of touch is crucial for medical training.

MUSEUM - For 3D digitization of priceless artifacts and objects from their sculpture and decorative arts collections.

ENTERTAINMENT - Haptics is used to enhance gaming experience.

MACBOOK - You force click by pressing on the trackpad and then applying more pressure. This allows you to take advantage of added functionality in many apps and system features on your Mac.

ADVANTAGES - HAPTICS Working time is reduces.

Communication is centered through touch and the digital world can behave like a real world.

Increase confidence in Medical Field.

With the Haptic Hardware and Software, user can feel as if they are touching the object it self.

DISADVANTAGES - HAPTICS Higher Cost.

Few Companies cannot afford Haptic Technology as its too costly.

Large Weight and Size.

The precision of touch requires a lot of advanced design.

LIMITATIONS High cost involved.

Large weight and size of haptic devices (Few devices).

Haptic interfaces can only exert forces with limited magnitude.

Haptic-rendering algorithms operate in discrete time whereas users operate in continuous time.

FUTURE VISION - HAPTICS HOLOGRAPHIC INTEGRATION - �The

feedback  will allows the user to interact with a hologram and receive tactile response as if the holographic object are real.

SMARTPHONES - In future, all smartphone companies will adopt this Technology.

SMARTWATCH - We can also see this haptic technology in Smartwatch in future.

CONCLUSION - HAPTICS Haptic Technologies have come a long way in bringing

this technology to reality.

Currently it is limited to Consumers.

Future generations of mobile devices and game console accessories will implement more haptic feedback.

Increasing applications of Haptics, the cost of the Haptic Devices will drop in future.

This Haptic Technology brings one step closer to Virtual World.
