What is haptics?

'Haptics' - derived from the Greek word meaning 'haptein' 'Haptics' - derived from the Greek word meaning 'haptein' which means to ‘contact‘ or ‘touch’.which means to ‘contact‘ or ‘touch’.

It is the ability to touch and feel virtual objects.

Reasons for its fast-growing use:Touch is capable of simultaneous input and output. Touch is at the core of personal experience.

Haptics = Touch = Connection

Characteristics of Haptics

““WHAT YOU SEE IS WHAT YOU SEE IS WHAT YOU FEEL !WHAT YOU FEEL !””

Unlike vision & audition, the haptic system can sense and act on the environment.

Can touch, feel, and manipulate objects in addition to seeing (and hearing) them.

HAPTICS - IntroductionHAPTICSHAPTICS Refers to sensing & manipulation

through touch. It includes:

1. HAPTIC TECHNOLOGY- Technology that interfaces

with the user through the sense of touch.

2. HAPTIC COMMUNICATION- The means by which people

communicate via touching.

3. HAPTICS PERCEPTION The process of recognizing

objects through touch.

Haptics TechnologyTechnology that interfaces to

the user via sense of touch by applying forces, vibrations, and/or motions to the user.

This mechanical stimulation is used to assist in the creation of virtual objects.

This emerging technology promises to have wide-reaching applications.

Haptics communication Means by which people

and computer communicate via touching.

Touch provides information about surfaces and textures .

Touch can convey messages specifically.

HAPTICS DEVICES

HAPTIC GLOVE

HIRO(Haptic Interface RObot)

FORCE-FEEDBACK GAMING DEVICES

1. Tactile : presence of heat & pressure.

2. Kinaesthetic :position, body movements and the forces which act on it.

3. Heat : gives the degree of hotness and coldness.

4. Texture : The roughness via friction measurement.

SENSORY INFORMTION

HAPTICS SYSTEM1. Sensor(s).

2. Actuator (motor) control circuitry.

3. One or more actuators that either vibrate or exert force.

4. Real-time algorithms actuator control software haptic effect library.

5. Application programming interface (API).

The API makes program calls to the actuator into the product’s OS.

The calls specify which effect in the haptic effect library to play.

When the user interacts with the product’s buttons, this control-position information is sent to the OS.

It then sends the play command through the control circuitry to the actuator.

HOW HAPTICS WORKS?

1. Force-feedback (Force-reflecting)

Deals with devices that interact with the muscles and tendons that give the human a sensation of a force being applied.

2. Tactile-Feedback

Deals with the devices that interact with the nerve endings in the skin which indicate heat, pressure, and texture.

TYPES OF HAPTIC FEEDBACKS

APPLICATIONS MEDICINE

CONSUSMER ELECTRONICS

MOBILE

INDUSTRIAL/

COMMERCIAL

AUTOMOTIVES

GAMING

Help the blind on reading books that are not written in Braille Characters.

Scanned letters are translated into Braille by electrical signal.

Projects the characters on the flat surface of the device whenever the user places it on the book.

It scans the text and converts it into voice that can be played through speaker.

1. Haptic Reader for the blind

2. Consumer Electronics

Samsung Cameras(TL220/TL225) -

Dual View Cameras Help Consumers Take the Perfect Self-Portrait on the Move

The smile detection feature automatically takes a photo when it senses a smile.

The haptic feedback on the rear LCD confirms when a selection is made.

Some simple haptic devices in the form of game controllers are force feedback joysticks and steering wheels.

E.g.: Simulated automobile

steering wheels that are programmed to provide a "feel" of the road.

3. Gaming

LG Cookie (LG KP500) Touchscreen Phone

with Tactile Feedback

Use tactile cues accompanying screen rotation, keypad slide, list scrolling etc.

Give the touch screen keypad touch effects for both button press and release.

4. Mobile

Immersion’s Immersion’s Endoscopy Endoscopy AccuTouch® AccuTouch® System:System:

Enables physicians to identify and address: Common complications. Become familiar with

the devices used during the procedure.

Patented force feedback technology offers a real feel for the procedure.

5. Medicine

A deaf person experiences the music, qualitatively similar to a normal person.

Haptic Chair has 4 contact speakers linked to a music source that vibrate in intensity according to the sound signals it receives.

AUDIO SIGNAL

DISCRETE VIBRO-TACTILE OUTPUT CHANNELS

LOGICAL PROGRESSION ALONG THE BACK OF THE BODY.

6. Haptic Chair/ Active Chair

The haptics jacket, designed by scientists at Philips ElectronicsPhilips Electronics..

Enables movie viewers to feel movies through a sense of touch.

Makes viewers feel anxiety and other emotions through signals such as:

Sending a SHIVER up the viewer's spine.

Creating TENSION in the limbs. Creating a pulse on the chest to

simulate a RAPID HEARTBEAT.

7. Haptic Jacket

PHANTOM OMNIA haptic device that teaches

visually impaired children how to write by providing them with a force-feedback.

Consists of a stylus mounted on a robotic arm.

Stylus moves and guides the hand of pupils in three dimensions.

8. Haptic Pen

1. Easy to understand & operates without prior knowledge.

2. Improves user performance, productivity & usability.

3. Large reduction in manipulation errors.

4. Works with a wide range of technologies.

ADVANTAGES OF HAPTICS

Using Technological developments we can feel the presence of our loved ones, in the near future.

FUTURE VISION

CONCLUSION HAPTICS ARE

IMPORTANT Training Experience Testing/Experimenting

DEVELOPING APPLICATIONS Faster Portable Easier/Understandable
