3. WHAT IS HAPTICS?
Haptics is related to sense of touch
which comes from the Greek word
HAPTESTHAI for to grasp or to
touch.
Touch is the first language.
From a very early age we become
sensitive to the specific qualities of
touch rather than its mere presence
or absence.
4. Haptics promises to open this
bottleneck by adding a new channel
of communication using the sense
of touch.
Haptics expands the notion of
bidirectional communication
between humans and computers to
include sensory feedback.
Haptics = Touch = Connection
5. Touch screens of all types the
ability to “touch back” with
unmistakable confirmation.
8. HISTORY
One of the earliest forms of haptic devices
is used in large modern aircraft that use
servomechanism systems to operate
control systems. Such systems tend to
be "one-way" in that forces applied
aerodynamically to the control surfaces are
not perceived at the controls, with the
missing normal forces simulated with
springs and weights.
9. HOW IT WORKS?
Haptics applications use specialized
hardware to provide sensory
feedback that simulates physical
properties and forces.
Haptic interfaces can take many forms;
a common configuration uses separate
mechanical linkages to connect a
person’s fingers to a computer interface.
12. Tactile information refers the information
acquired by the sensors which are actually connected
to the skin of the human body with a particular
reference to the spatial distribution of pressure, or
more generally, tractions, across the contact area.
For example when we handle flexible
materials like fabric and paper, we sense
the pressure variation across the fingertip.
This is actually a sort of tactile information.
13. FUNCTIONS OF HAPTICS :How touch and its underlying brain functions work :-
Haptic technology:- technology that
interfaces with the user through the sense
of touch.
Haptic communication:- the means by
which people and other animals
communicate via touching.
14. Haptic perception:- the process of
recognizing objects through touch.
Haptic poetry:- a liminal art form
combining characteristics of typography
and sculpture.
15. HAPTICS COMMUNICATION
Haptic communication is the means by
which people and other animals
communicate via touching.
It providing information about surfaces
and textures.
It is a component of nonverbal
communication in interpersonal
relationships, and vital in conveying
physical intimacy.
16. Human babies
have been
observed to
have enormous
difficulty
surviving if
they do not
possess a sense
of touch, even
if they retain
sight and
hearing.
17. In chimpanzees the sense of
touch is highly developed. As
new borns they see and hear
poorly but cling strongly to their
mothers.
Heslin (1974) outlines the four
haptic categories:
Functional/professional
Social/polite
Friendship/warmth
Love/intimacy
20. HAPTIC TECHNOLOGY
• Every
applications
use the haptic
concepts directly
or indirectly.
• In this fig. in
touchscreen cell,
internally there
are very small
boxes. when we
touch any
button, it will
sense that what
we want. And it
give it as a
output.
22. A form of computing that offers “a natural way
of interacting with information,” rather than
the “traditional user interface.”
Direct Interaction: The ability to "grab"
digital information with hands - interacting
with touch/gesture, not with a mouse or
keyboard.
Multi–Touch: The ability to recognize
multiple points of contact at the same time,
not just one (Ex. One finger, like with most
touch screens), but dozens.
Multi–User: The Surface’s screen is
horizontal, allowing many people to come
together around it and experience a
“collaborative, face–to–face
computing experience”.
Object Recognition: Physical objects can be
placed on the Surface’s screen to “trigger
different types of digital responses” (Ex.
cell phones, cameras, & glasses of wine).

23. 3-D gaming
Disney Research,
Pittsburg (DRP) has
shown off a
revolutionary
technology called
‘Surround Haptics’ that
can bring real life
experience in video
gaming and film
watching.
24. HAPTIC DEVICES
A haptic device is the one that provides a
physical interface between the user and the
virtual environment by means of a computer.
This can be done through an input/output device
that senses the body movement, such as joystick
or data glove.
By using haptic devices, the user can not only
feed information to the computer but can also
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.

31. Territoriality is personal space we don't
want others to invade.
Lyman and Scott (1967) identify 3 types of territorial
encroachments:
Invasion
Violation
Contamination
32. Invasion
INVASION is more all-encompassing and permanent. It is an
attempt to take over another's territory.
Violation
VIOLATION involves the unwarranted use of another's
territory. This may be done with the eyes, the voice or other
sounds, or with the body.
33. Contamination
CONTAMINATION is defiling another's territory, not by
presence but what we leave behind.
Defense
The 2 primary methods for territorial defense are:
Prevention
Reaction
34. If the prevention of territorial violations
does not work, how do people react?
35. Reaction
One response to invasion of our privacy is behavior that
restores our privacy zone. This response accepts the
invitation and cedes the territory.
Another response is the well-known elevator phenomenon,
in which people are crowded more closely than they like, so
everyone looks up or down as if to say “I’m not trying to
intrude into your space.”
A third response is to challenge the invasion—to stand your
ground and refuse to yield territory.
