Tele Immersion Full Seminar Report. ABSTRACT Tele -immersion is an advanced form of virtual reality that will allow users in different places to interact in real time in a shared simulated environment. This technology causes users to feel as if they were in the same room. The tele-immersion technology uses a "tele-cubicle" which is equipped with large screens, scanners, sensors, and cameras.
The tele-cubicles are linked together in real-time so that they form one larger cubicle. Through the virtual environment, participants are able to interact with other group members. Also, virtual objects and data can be passed through the walls between participants, and placed on the shared table in the middle for viewing.
Tele immersion has the potential to significantly impact educational, scientific, manufacturing, and many other fields. Internet 2 is the successor to the "commodity Internet", as the existing Internet is now known. Internet 2 is a collaborative project, overseen by the University Corporation for Advanced Internet Development, and worked on by US universities and a number of government agencies and corporate sponsors.
However you have visitors from Japan coming to ink a mega business deal the same day. So you go to a room you call the holodeck. There, inside a simulated environment, you contact your business associates using information technology. You are able to conduct a meeting with them almost as if you in Chennai. You even shake hands with their holographic images, because they seem to be right there! With tele-immersion you will interact instantly with your friend on the other side of the globe through a simulated holographic environment.
This technology, which will come along with internet2, will change the way we work, study and get medical help. It will change the way we live. Users will feel as if they are actually looking, talking and meeting with each other face to face in the same place, even though they may be miles apart physically. In a tele-immersive environment, computer recognized the presence and movements of individuals as well as physical and virtual objects.
They can then track these people and nonliving objects, and project them in a realistic way across many geographic locations. The three steps to constructing a holographic environment are: The computer recognizes the presence and movements of people and objects.
The computer tracks those images. The computer projects those images on a strereoimmersive surface. Simulated environment to replicate real time movements. By combining cameras and Internet telephony, video conferencing has allowed real time exchange of more information than ever, without physically bringing each person into one central room. It described a graphics display that would allow the user to experience a completely computer rendered environment.
In , Abilene, a backbone research project, was launched and now serves as a base for Internet2 research. The head of advanced network and services proposed tele-immersion at the application that could drive internet2 research forward.
That is how the national tele-immersion initiative as formed in may, researchers at the Universities of North Carolina UNC , the Universities of Pennsylvania and advanced network and services reached a milestone in developing this technology. Today scientists are still developing this new communication technology. There are several groups working together on the national tele-immersion initiative NTII to make this wonderful technology available to the common men.
At the other end, the people, who appeared as 3d image, where tracked with and array of 8 ordinary video cameras while three other video cameras captured real life patterns projected in each room to calculate distance.
This enabled the proper depth to the recreated on the screen. So if an observer move here head to the left, she could see the corresponding image that would be seen if she were actually in the room with the person on the screen.
Views of cameras Tele immersed environment Scientists are developing new technologies support this type of communication. Apart of these new technologies is: Tele cubical : Users will communicate by using this technology. It consist of a Stereo immersive desk surface and two stereoimmersive wall surfaces. These three display surfaces join to form a virtual conference table in the centre.
This will allow the realistic inclusion of tele-immersion into the work environment, as it will take up the usual amount of desk space. Internet2 : This will replace the current internet infrastructure. This high bandwidth, high speed network is necessary to transfer the large amounts of data that tele-immersion will produce. Bandwidth issues : Network bandwidth required to make tele-immersion work is one of the main concerns of this new technology.
It is estimated that as much as 1. This is much higher than the average home connection bandwidth. The exact amount of bandwidth needed for each scene depends on the complexity of the background. With time, the number of megabits used will fall as advanced compression techniques are established.
This can carry megabits per second and supports, at a basic level, a three way conversation. Although OC3 lines are times faster than normal broadband, they are also more expensive. Initially, bandwidth-intensive application will have to be limited to the larger organizations that can afford high connection speeds. The amount of data sent to render this tele-presence will also require fast processing power. This will need to be available as required on the internet.
A new network called the Grid could be a solution. The Grid will use distributed computing. There are not enough supercomputers to ideal with the enormous amount of data that will rush through the net in the future.
As a solution, new network will connect their PCs so they can share processing power and hard disk space. They will be locked into a grideffectively creating one supercomputer. Haptic sensors : would allow to touch projections as if they were real. Desktop supercomputers : would perform the trillions of calculations needed to create a holographic environment. A network of computers that share power could also possibly support these environments.
Following the flow of information tele-immersion depends on intense data processing at each end of a connection, mediated by high performance network. From the sender : Parallel processors accept visual inputs from the cameras and reinterpret the scene as a 3-Dimensional computer model. To the receiver : Specific rendering of remote people and places are synthesized from the model as it is received to match the point of view of each eye of a user.
The whole process repeats many times a second to keep up with the user head motion Generating the 3-d image : 1. An array of cameras views people and their surroundings from different angle. Each camera generates an image from its point of view many times in a second. Each set of the images taken at a given instant is sorted into subsets of overlapping trios of images views taken by the cameras 3. The disparities are then analyzed to yield depths that would account for the differences between what each camera sees.
All the depth maps are combined into a single viewpoint independent sculptural model of the scene at a given moment.
Process of combining the depth maps provide maps opportunities Tele -immersion and virtual reality : Tele -immersion may sound like virtual reality but there are major differences between the two technologies. While virtual reality allows you to move in a computergenerated 3-D environment, tele-immersion can only create a 3d environment that you can see but not interact with. However, interaction is possible by combining the two technologies.
Imagine a video game free of joysticks, in which you become a participant in the game, fighting monsters or scoring touchdowns. Instead of traveling hundreds of miles to visit your relatives during the holidays, you can simply call them up and join them in a shared holographic room. Doctors and Soldiers could use tele-immersion to train in a simulated environment.
Building inspectors could tour structures without living their desks. Automobile designers from different continents could meet to develop the next generation of vehicles. Surgeons indifferent geographical space could experiment with virtual medical procedures before working on actual patients.
Medical technologies that are physically inaccessible in some places could be used to save lives by manipulating virtual models, instance, offshore oilrigs and ships. In the entertainment industry, ballroom dancers could train together from separate physical spaces. Instead of commuting to work for a board meeting, business persons could attend it by projecting themselves into the conference room. The list of applications is large and varied, and one thing is crystal clear- this technology will significantly affect the educational, scientific and medical sectors.
Medicine : Tele -immersion can be immense use the field of medicine. The way medicine is thought and practiced has always been very hands-on. It is impossible to treat a patient over the phone or give instructions for a tumour to be removed without physically being there.
With the help of tele-immersion, 3d surgical learning for virtual operation is now in place and, in the future, the hope is to be able to carry out real surgery on real patients.
A geographically distanced surgeon could be tele-immersed into an operation theatre to perform an operation. This could patiently be life saving if the patient is in need of special care either a technique or a piece of equipment , which is not available at the particular location.
The argument against this is: how reliable is this technology? What would be the legal implication if the technology fails suddenly and the tele-immersed surgeon disappears in the middle of an operation, with the patient left without medical help?
How accurate are the movements of the transported doctor when within an environment? These are difficult questions to answer and there are bond to be many skeptics. Uses in Education : In education, tele-immersion can be used to bring together students at remote sites in a single environment relationship among educational institutions could improve tremendously in the future with the use of tele-immersion.
Already, the academic world is sharing information on research and development to better the end results. Tele immersion will only promote this collaboration. This will be distinct advantage in surgical training. While it will not replace the hands on training, this technology will give surgeons a chance to learn complex situations before the treat their patients. With tele-immersion in schools, students could have access to data or control a telescope from a remote location, or meet the students from other countries by projecting themselves into a foreign space.
Internet2 will provide access to digital libraries and labs, opening up the lines of communication for students.

It is and you have a very important meeting with your business. However you have visitors from Japan coming for a mega. Is there any technology by which you can deal with both of. The answer is yes and the name of that technology is Tele-Immersion.
Tele-Immersion is a new medium that enables a user to share a virtual space with remote participants. The user is immersed in a 3D world that is transmitted from a remote site. This medium for human interaction, enabled by digital technology, approximates the illusion that a person is in the same physical space as others, even though they may be thousands of miles distant. It combines the display and interaction techniques of virtual reality with new computer-vision technologies.
