ABSTRACT
 This project describes the design and the development of hardware and
software of a portable Virtual Reality Headset.
 It is responsible for the execution of main software and display of the
rendered images on the screen.
 The Inertial Measurement Unit (IMU) present in the device tracks the
users head movement and communicates with Rasberry Pi using the
Arduino platform and is basically used for following reasons.
1.For remote complete view of surroundings in order to execute any task more
effectively.
2.To enhance the capability of operation involved in tele-operation of patient.
INTRODUCTION
 This is an innovative approach towards real time implementation for virtual reality
environment.
 In this system, we have used a concept of real time position tracking of wearable gadget;
also video screen is optimized in such a way that it will show real time clear view of the
camera signal with proper focal length adjustment.
 Multi-Axis accelerometer or gyroscope MEMS sensor is used for head movement in all
direction for 360 degree tracking. By proper scaling exact replica actions are performed
on the remote end to the for 3D movement of the camera lens which will makes the
virtually presence of the viewer at the point. So as operator moves his head in 3D
movement, viewer gets exact same view as of remote real location environment. The
surveillance vehicle will be driven with the help of remote control based on wireless long
range connectivity media.
TRANSMITTER RECEIVER
BLOCK DIAGRAM DESCRIPTION
 As shown in block diagram, whole system is divided into two main parts; at transmitter end the system is
controlled by the main processing unit as atmega avr based core.
 As an primary sensor, the 3 axis gyro is connected which will track the real time head position of the head or its
movement in all direction and based on the values the data command are transmitted to the receiver unit for
servo mechanism for camera movement in same proportion.
 On the same channel the remote control signals are also send to operate the complete robot vehicle movement
in all directions.
 These both the signals are transmitted in 2.4HGz RF link with long range operationally capabilities. Whereas video
and audio signals are transmitted on 135-145 KHz frequency.
 On receiver remote vehicle end, the head potion data is decoded and send to the servo driver and this will
control dual link assemble for the 3D movement if the camera in all the direction. The movement of the complete
robot is done by motor driver and wheel assembly.
 This camera is having the capabilities to work under night or day light conditions and also captures the audio with
the video signals with the help of built in mic. This encoded video-audio data is transmitted on low RF frequency
to the receiver end.
 On receiver and TFT display with video decoder is used which shows the real time video captured by the camera.
Portable power supply is provided on both the end for easy handling operation and portability.
Controller AVR-
ATMEGA 328
 It is 8 bit AVR RISC based
microcontroller.
 It’s operate between 1.8-
5.5v
Display – LCD –
Graphics TFT
Display
 It is 7” TFT display.
 It can be used in any
embedded system &
Industrial devices.
Camera – 1.2GHz RF
link CAM
 Two 1.2GHz 6dBi or 2.4GHz 7dBi.
 omni-directional antennas for the
camera and the receiver.
 It captures audio & visual signals.
CIRCUIT AND HW/SW REQUIREMENT
RF Channel – 2.4G
Hz link
RF data modem working at
2.4 Ghz frequency in half
duplex mode with automatic
switching of receive/transmit
mode with LED indication.
Accelerometer –
ADXL 335
 A dynamic sensor
capable of a vast range
of sensing.
 It can measure
acceleration in one, two,
or three orthogonal axes.
Software
1. Langauge –
Embedded ‘C’.
2. Compiler –
Arduino IDE.
 We can implement this on robotic arm which can used operation or automobile assembly
operation.
 Everything we experience in life can be reduced to electrical activity stimulating our brains as
our sensory organs deliver information about the external world. This interpretation is what we
consider to be "reality." In this sense, the brain is reality.
 Everything you see, hear, feel, taste and smell is an interpretation of what's outside, and
created entirely inside your head. We tend to believe that this interpretation matches very
closely to the external world. Nothing could be further from the truth.
 VR is the ultimate medium of syntactical intent; the only way to figuratively "show" someone
exactly what you mean is to literally show them. Words are exceptionally ineffective at
conveying meaning, as they are a low-bandwidth, lossy medium of knowledge transference.
 Virtual reality is a software created, artificial environment that places the user in what seems
like a real life situation.
 The future seems good in India as well. India has a large resource of gamers and engineers who
can build affordable VR technology for Indians.
APPLICATON
1 Can be used in hospital visit
2 Can be used in Military operation
3 Can be used in Rescue operation
4 Can be used in Police Training
5 Can be used to Helping The Paralyzed
6 Can be used in Surgery Simulators
7 Can be used in Architecture
CONCLUSION & REFERENCES
By considering above said system, we can
conclude that this system will give a virtual
presence at the remote location with the
help of advance visual capabilities and
with effective control over the operation
of the robot vehicle.
 This system will enhance the performance
in the application of rescue or medical
field with more effective handling and
view of the location or object.

  • 4. INTRODUCTION  This is an innovative approach towards real time implementation for virtual reality environment.  In this system, we have used a concept of real time position tracking of wearable gadget; also video screen is optimized in such a way that it will show real time clear view of the camera signal with proper focal length adjustment.  Multi-Axis accelerometer or gyroscope MEMS sensor is used for head movement in all direction for 360 degree tracking. By proper scaling exact replica actions are performed on the remote end to the for 3D movement of the camera lens which will makes the virtually presence of the viewer at the point. So as operator moves his head in 3D movement, viewer gets exact same view as of remote real location environment. The surveillance vehicle will be driven with the help of remote control based on wireless long range connectivity media.
  • 6. BLOCK DIAGRAM DESCRIPTION  As shown in block diagram, whole system is divided into two main parts; at transmitter end the system is controlled by the main processing unit as atmega avr based core.  As an primary sensor, the 3 axis gyro is connected which will track the real time head position of the head or its movement in all direction and based on the values the data command are transmitted to the receiver unit for servo mechanism for camera movement in same proportion.  On the same channel the remote control signals are also send to operate the complete robot vehicle movement in all directions.  These both the signals are transmitted in 2.4HGz RF link with long range operationally capabilities. Whereas video and audio signals are transmitted on 135-145 KHz frequency.  On receiver remote vehicle end, the head potion data is decoded and send to the servo driver and this will control dual link assemble for the 3D movement if the camera in all the direction. The movement of the complete robot is done by motor driver and wheel assembly.  This camera is having the capabilities to work under night or day light conditions and also captures the audio with the video signals with the help of built in mic. This encoded video-audio data is transmitted on low RF frequency to the receiver end.  On receiver and TFT display with video decoder is used which shows the real time video captured by the camera. Portable power supply is provided on both the end for easy handling operation and portability.

This interpretation is what we consider to be "reality." In this sense, the brain is reality.  Everything you see, hear, feel, taste and smell is an interpretation of what's outside, and created entirely inside your head. We tend to believe that this interpretation matches very closely to the external world. Nothing could be further from the truth.  VR is the ultimate medium of syntactical intent; the only way to figuratively "show" someone exactly what you mean is to literally show them. Words are exceptionally ineffective at conveying meaning, as they are a low-bandwidth, lossy medium of knowledge transference.  Virtual reality is a software created, artificial environment that places the user in what seems like a real life situation.  The future seems good in India as well. India has a large resource of gamers and engineers who can build affordable VR technology for Indians.
