This document discusses gestures, including their categories, social significance, and relationship to neurology. It defines a gesture as a form of non-verbal communication that uses visible bodily motions to convey messages instead of speech. Gestures are divided into categories like beat gestures used during speech and iconic gestures that elaborate speech meaning. The document also discusses the social roles of gestures across cultures and how both gestures and spoken language are represented together in the brain, with gestures helping facilitate understanding. It concludes by noting how technology is now able to interact with gestures through computer vision and motion detection.

3.  A gesture is a form of non-verbal communication or non-

when we speak & which are closely coordinated with
speech.
 Iconic :- It is used during speech production known as
iconic gestures are more full of content, and may echo,
or elaborate, the meaning of the co-occurring speech.

 Language development :- Young children under the age
of two seem to rely on pointing gestures to refer to
objects that they do not know the names of. Once the
words are learned language they didn't use the signs.

5.  Single handed gestures:-
Okay sign made by connecting the thumb and forefinger
in a circle and holding the other fingers straight.

6.  It play a central role in religious or spiritual rituals such as
the Christian sign of the cross.
 In Hinduism and Buddhism, a mudra (Sanskrit, literally

important.
 In France, “a light, quick handshake is common. To offer
a strong, pumping handshake would be considered
uncultured.

7.  Both symbolic gesture and spoken language in the
present human brain.
 A way to represent the thoughts of an individual, which
are prompted in working memory.
 “The understanding of gestures is not the same as
understanding spoken language."
 These two functions work together and gestures help
facilitate understanding, but they only "partly drive the
neural language system.“
 speech and gesture are innately linked in the brain and
work in an efficiently wired and choreographed system.

8.  The movement of gestures can be used to interact with
technology like computers, using touch or multi-touch
popularised by the Smartphone's.
 The development in the technology for betterment of the
Human begin for there suitable work.
 It can be conducted with techniques from computer
vision and image processing.
 Now the physical movement detection and visual motion
capture , used in video game consoles.
