What is gesture????

Gesture –any “moment’’.

Gesture is a form of non-verbal communication in which visible bodily actions communication particular message, either in place or speech or together and in parallel words.

Gestures can originate from any bodily motion or state but commonly originate from the face or hand.

3

Types of gesture

Dynamic- This gesture change over a period of time .ex A waving hand means “goodbye”.

Static- This gesture is in stable period of time. ex A stop hand. Gesture to Gesture recognition

This involves: 1) A posture: A static configuration without the movement of

the body part. 2) A gesture: A dynamic movement of the body part.

4

Objective

Provide the physically challenged users a better way to interact with the computers.

Provide a more natural Human Computer Interface. Helpful for handicap people. Interfacing user with software. Direction as well as count both will be responsible for the

hardware control.

Introduction

Two common technologies for hand gesture recognitionglove-based method• Using special glove-based device to extract hand

posture• Annoying

vision-based method• 3D hand/arm modeling• Appearance modeling

6

History

The hand gesture recognition is developed by many scienst in different field.Tin H -Hand tracking and recognize MAL (Myanmar Alphabets Language)William F -First Implementation of gesture recognition and real time. Manar M.- Developed ArSL(Arabic sign language)

7

CSL and Pre-processing

CSL is the abbreviation for Chinese Sign Language.

30 letters in CSL alphabet Objects in recognition.

Pre-processing hand gesture recognition

Detection of Hand Gesture Regions

Aim to fix on the valid frames and locate the hand region from the rest of the image.

Low time consuming fast processing rate real time speed

Detect skin region from the rest of the image by using color. Each color has three components RGB.

Three Stages Of Hand gesture

10

Inputs Devices

The ability to track person’s movement and some variation within tool and environment

Wired gloves-To detect the hand moments,postion n rotation (5- 10 degree).

Depth aware camera-Useful to detect the hand in short range (approximate a 3D representation ).

Single camera –Normal camera.

30 different gestures, 120 samples/gesture36*36 pixels3600 training samples vs. d = 1296Difficult to describe the data distributionReduce the dimensionality of hand gesture images

16

Based on the representation by skin pixels can be detected and form a binary image sequence M’(x,y,t) – region maskAnother binary image sequence M’’(x,y,t) which reflects the motion information is produced between every consecutive pair of intensity images – motion mask

Transformed the detection results into gray-scale images with 36*36 pixels.

Advantages

Able to understand people better.

Comm. Is able to carry out in an emergency.

Used for handicap people.

The system is connected in simple and active way.

Easy to used, no need to use special hardware.

System is fast, modular.

17

Disadvantages

High cost

Some assumption was made for the system like:-

o Input image include.o Many hand can perform the device.o Gesture are made with right hand only.o The arm must be vertical.o The palm is facing towards the camera.

18

conclusion

The most important of this hand gesture based in input modes is that using this method.

The user can interact with the application from a distance without using the keyboard or mouse

And in future scope we can design a framework through a application domain.

Also the framework may be useful for controlling different types of games which can be control by the hand gesture recognition
