Teleimmersion

Introduction

Using teleimmersion, you can visit an individual across the world without stepping a foot outside your room. Advancements in telecommunication and media compression and processing techniques make telecommunicating geographically possible. A National Tele-Immersion Initiative leads the way to make all these things possible. They are working on projects to have users share the same physical space in a real time world, as if they are sitting in front of each other in the same room. In this regard, Advanced Network & Services played a vital role, to bring together the experts in this field together. Jaron Lanier, one of the pioneers in development of Virtual Reality (which according to him is “the brain anticipates a virtual world instead of the physical one”) in 1980’s, is involved with the team, which started work in middle of 1997 with collaboration from Brown University, Providence Naval Post Guard School, Monterey University of North Carolina, Chapel Hill, University of Pennsylvania, Philadelphia, and University of California, Berkeley.

What 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. Thus with the aid of this new technology, users at geographically distributed sites can collaborate in real time in a shared, simulated, hybrid environment submerging in one another’s presence and feel as if they are sharing the same physical space. It is the ultimate synthesis of media technologies:

• 3D environment scanning
• projective and display technologies
• tracking technologies
• audio technologies

The considerable requirements for tele-immersion system, make it one of the most challenging net applications.

In a tele-immersive environment computers recognize the presence and movements of individuals and objects, track those individuals and images, and then permit them to be projected in realistic, multiple, geographically distributed immersive environments on stereo-immersive surfaces. This requires sampling and resynthesis of the physical environment as well as the users' faces and bodies, which is a new challenge that will move the range of emerging technologies, such as scene depth extraction and warp rendering, to the next level.

Tele-immersive environments will therefore facilitate not only interaction between users themselves but also between users and computer generated models and simulations. This will require expanding the boundaries of computer vision, tracking, display, and rendering technologies. As a result, all of this will enable users to achieve a compelling experience and it will lay the groundwork for a higher degree of their inclusion into the entire system.

Tele-immersive systems have potential to significantly change educational, scientific and manufacturing paradigms. They will show their full strength in the systems where having 3D reconstructed ‘real’ objects coupled with 3D virtual objects is crucial for the successful fulfillment of the tasks. It may also be the case that some tasks would not be possible to complete without having such combination of sensory information. There are several applications that will profit from tele-immersive systems. Collaborative mechanical CAD applications as well as different medical applications are two that will benefit significantly.

Tele-immersion may sound like conventional video conferencing. But it is much more. Where video conferencing delivers flat images to a screen, tele-immersion recreates an entire remote environment. Although not so, tele-immersion may seem like another kind of virtual reality. Virtual reality allows people to move around in a pre-programmed representation of a 3D environment, whereas tele-immersion is measuring the real world and conveying the results to the sensory system.

Sony Adds Virtual Expander to Micro Vault USB Storage Media - an old Article

PARK RIDGE, N.J., May, 31, 2005 -- Sony's latest enhancements to its Micro Vaultâ„¢ USB storage media line include a new Virtual Expander feature that stretches the virtual capacity of the device to store as much as three times more data. 

The Virtual Expander feature is included in the latest Classic and Mini Micro Vault designs. 

In addition, Sony is introducing the Micro Vault Turbo with a rapid 28MB/sec maximum transfer speed. Together, these products create a comprehensive offering for increasingly storage-hungry users who need to take more data and high quality multimedia content wherever they go. 

"Virtual Expander meets the ever-increasing need for more storage, freeing Micro Vault users to store, share and transport more data than ever," said Mike Lucas, director of marketing for Sony Electronics' consumer media group. "This new feature is extremely attractive because it adds versatility and value for consumers." 

Good in a Crunch

The Virtual Expander feature is an integrated feature that allows users to virtually squeeze more into their Micro Vault media effortlessly. Files are automatically compressed/decompressed when loaded on and off, creating virtual storage that is as much as three times the native capacity (depending on file type - already compressed files may not compress further). Once activated, users maximize their storage capabilities seamlessly. Users can choose to compress individual files or the entire device contents at once. 

Speedier Storage, Greater Security

Another advance in Sony's storage lineup is Micro Vault Turbo, featuring a pace setting 28MB/sec maximum transfer speed and a software suite featuring Password Lock. Micro Vault Turbo media makes quick work of moving large amounts of data and accessing large files such as high-resolution pictures or DVD-quality video. Micro Vault Turbo media comes in a champagne-color shell and offers 1GB capacity. 

Other offerings that round out the Micro Vault lineup include the Fingerprint Access Micro Vault with advanced biometric security plus file encryption for protecting sensitive information and Micro Vault Pro media, delivering 5GB of high-speed storage in a form factor about the length and width of a business card. 

Storage for Today's Digital Lifestyle

"Micro Vault is a powerful tool to extend our digital lifestyles wherever we go, Lucas said. "Consumers want their data at their fingertips, and this makes it easy." 

Micro Vault media with the Virtual Expander feature is currently shipping at the same suggested retail prices as the prior Micro Vault line. Micro Vault Turbo media will ship in June at a suggested retail price of $129.99. 

Professional way of setting Passwords

1. Use a minimum of eight characters; more characters are better, as long as you are comfortable remembering them are typing them.
2. Do not base the password on a dictionary word. Eg: redhat
3. use a variety of different types of characters; use at least three of the following
1. lower case letters
2. upper case letters (passwords are generally case sensitive)
3. numbers
4. punctuation and other special characters
4. avoid using your real name, login name or variations thereof

eg: with a login name of sally, a poor password would be s@lly.

5. Avoid using easy to determine personal information, such as your birthday, anniversary, etc.
6. avoid using formulas, such as 1+1=2
7. Avoid excessive complexity if it tempts you to perform such unsafe practice as writing the password onto a notepad near your monitor.

File Systems - An overview

            File system is the system that is used to store/retrieve the information or data in a stable way for future purpose in a hard disk. This file system may vary from operating system to operating system. To maintain the communication between one operating system to other install different operating systems in a common file system or mount the relevant file system drives whenever necessary. Let us know the basic Windows file systems and Linux file systems in this article.

Windows File systems

Even though there are several file systems in the various operating system environments, the four major are taking into account normally as far as Windows operating system is concerned.

FAT 16/FAT

            File Allocation Table 16 bit is the expansion of FAT16. FAT is the short form for expressing FAT16 in Windows latest versions in these days. This is the oldest file system which will be no longer in use.

            Access to files on a local partition is available through MS-DOS, all versions of Windows, and OS/2.

FAT 32

            This holds 32 bit for storing data and more securer than FAT16/FAT. This is normally used by the Windows and Linux beginners.

            Access to files on a local partition is available only through Windows 95 OSR2, Windows 98, Windows Millennium Edition, Windows 2000, Windows XP, and products in the Windows Server 2003 family.

Figure 1File System Interface

NTFS

            New Technology File System is the expansion of NTFS which holds advance operations in Windows. This is used for Windows and Linux advanced users. Advanced security, compression, encryption and quota management are the salient features of this file system.

A computer running Windows 2000, Windows XP, or a product in the Windows Server 2003 family can access files on a local NTFS partition. A computer running Windows NT 4.0 with Service Pack 5 or later might be able to access some files. Other operating systems allow no local access.

CDFS

            This is the file system that is used in compact disk which holds the expansion of Compact Disk File System. This is platform independent file system and it can be used for reading as well as writing the information on compact disc. This is commonly used by all kinds of users.

The following table is explained us the difference between the various file systems in the operating system Windows.

Types	FAT 16	FAT 32	NTFS	CDFS
Cluster size	16KB to 64KB	4KB	4KB	No cluster size
Maximum partition size	4GB	32 GB	2TB	700-800MB
Security	No	No	Advanced security policies	-
Compression	No	No	Yes	-
Encryption	No	No	Yes	-
Quota	No	No	Yes	-
Quota Management	No	No	Yes	-

Linux File systems

In Linux operating system, we have four major file systems that are commonly used world wide in these days.

ext2

            This is the file system that is used to install Linux normally little bit earlier. There is no journaling support. We can use this file system now also for installing.

Command to format a partition in ext2   mkfs.ext2

Instance: mkfs.ext2 /dev/hda3

ext3

            It is another file system that is also used to install Linux in these days which holds the journaling facility. The journaling facility is having the online database updation service, which is commonly used in the real-life situations.

Command to format a partition in ext3   mkfs.ext3

Instance: mkfs.ext3 /dev/hda3

            FAT/FAT16/FAT32 file systems can be mounted easily with the ext2 as well as ext3 file systems. For mounting ntfs file system, the third party rpm (tool) has to be downloaded from the internet. (for further reference: http://www.rpmfind.org)

Figure 2 File System Overview

vfat

            FAT/FAT16/FAT32 is considered as vfat as far as Linux operating system is concerned. Virtual File Allocation Table is the expansion of this file system. This is generally used for sharing files between Windows and Linux.

swap

            This is the special type file system which doesn’t have the mount point in Linux. This is creating virtual memory for running other applications in the operating system specified. Normally it has the size of the double of the RAM size of the specified system.

The following table explains about the various file systems in Linux

Types	Ext2/Ext3/vfat	Swap
Mount point	Yes	No
Accessed by Windows	No	No
Can it access Windows	Yes	Yes
Partition size	User’s wish	User’s wish / double the RAM size normally
Quota	Yes	Not applicable
Reformatted	Yes	Not applicable
Priority setting	Can’t set	Can set

Note:

1. There is no explicit swap file system in Windows environment. Virtual memory is using to replace the swap file system in Windows.
2. If in the case of installing dual operating systems in a single machine (say Windows 2003 and Linux Enterprise 5.0), we can fix the swap file system as a single file.
3. The administrator can expand the virtual file system in Windows after installing the specified operating system. Similar to that the swap file system size can be extended after installing operating systems. More than one swap file system partitions can be created and fixed up the priorities for those things in Linux environment.

DFS (Distributed File System) is another file system that is available Windows 2003 server. It is used to distribute the information through out the network in windows environment only.

Distributed File System (DFS) can be used to make it easier for users to access and manage files that are physically distributed across a network. With DFS, can make files that are distributed across multiple servers appear to users as if they reside in one place on the network.
