If a new webcam technology from Microsoft get the go-ahead, then instant messaging could get a whole lot more interesting.

Currently under development at the Microsoft research labs in Cambridge, England, the new webcam, i2i consists of two lenses, which carefully follows an individuals movement. Using an exclusively developed algorithm to cleverly blend what each lens is seeing, resulting in the creation of an accurate stereo "cylopean" image.

All very technical, but for the 18.5 million people source Microsoft who regularly use webcams while they are using instant messengers, i2i means that it will appear as if users are looking into each others eyes.

Antonio Criminisi, lead researcher of Microsofts Machine Learning and Perception Group, said.

"We were able to come up with an algorithm that was able to take two images and capture a corresponding map in 3D. Using this powerful technology, we can now synthetically create an image as if the person is looking straight into your eyes."

According to Dr Criminisi, the biggest challenge for the backroom boys at Microsoft was in calculating how the visual brain works. In particular, how it sees and sorts out colors, shapes and distances.

"Essentially, what we have done is replace human eyes with cameras and the human brain with a computer."

The real magic behind this technology is the newly developed stereo algorithm, which makes it possible to accurately reconstruct a 3D, geometric image in real time and on a standard computer. Fundamentally, this is the same technology which was used to recreate the stunning 3D images of the Martian surface, which were beamed back by the NASA rover.

With the ability to generate realistic looking background images in order that users can pretend they are somewhere other than where they really are! Commenting, Dr Criminisi said.

"This is important for privacy, as I may not want you to see how untidy my bedroom is."

A feature likely to capture the teens market is that of Smart Icons. Instead of typing in the usual pictorial emotion e.g. : i2i can superimpose free floating, 3D ones which can then be instructed to float freely around a persons head or anywhere else for that matter.

While Dr Criminisi admits there are still issues to iron out before the project is passed on to Microsoft Development, he is pleased with what has been achieved in under two years. Dr Criminisis team is already experimenting with code which enables users to create their own wrap-around avatar, 3D face and then have it move as if it were their own.

You really enjoy those dvd movies and games and the last thing you need or want is to experience problems with your dvd drive.

To prepare for the possibility of having your dvd drive leaving you out in the cold one morning,we will dicuss problems that may cause dvd failure as well as the procedures you should take to correct these problems.

As with all drives,be sure to double check the failure. If the dvd drive will not read the dvd, try running another dvd in the drive. Make sure the dvd has no scratches and is clean.

Visually inspect the drive if the drive is external and if the drive is enternal,check the computer.Check to see if the computer has good ventilation to help keep it cool.Here are the common dvd problems with their solutions.

DVD DRIVE HAS NO POWER

First..For external drives that have no power,first check to see if anything or anyone has caused the power cord to become unplugged.Rule out the wall outlet by plugging in another device such as a radio and see if it plays.

Second...If youve proven the wall outlet to be good,but you still dont have power,check the surge protector for any signs of damage.If the surge protector is good,check the cord.

Third..If youre certain the surge protector or wall outlet is providing power,double check the cord by plugging it in a few times.If no power is present,you will have to replace the cord or the drive itself.

Internal dvd drives receive their power from the connector from the power supply.Try another connector to the drive. if the internal dvd drive still does not receive power after using another connector,the drive is faulty.

DRIVE HAS POWER BUT TRAY WONT OPEN

You may experience the tray failing to open.Should this happen,press the button a couple times to see if it will open.If the tray fail to open,reboot your computer and try to open the tray.

When rebooting the system,notice the monitor to see if the drive is recognized by the computer.Some systems will not display installed hardware during bootup.If this is the case,you will have to access your BIOS to check if the dvd drive is being registered.

You can also try the manual eject button on the drive to get it to open.Use something very small but firm to press in the pinhole in front of the drive to open the tray.

Shut the computer off and unplug it.Use something like a long paperclip to insert in the pinhole to open the tray. The tray may open a couple inches and you can grab it with your fingers to open it completely.

DRIVE IS NOT RECOGNIZED BY WINDOWS

Be sure the operating system is recognizing the drive by clicking on My Computer.Windows XP will show "drives with removable storage".If your drive is present, highlight the drive,right click and select properties.Click on properties and you should see "this drive is working properly".

If you see another message such as "this drive is not working properly",you may be able to update the device driver.If the drive is not present in My computer,reboot the computer and access the cmos setup.

In the cmos setup,the dvd drive should be present.The drive may not be properly installed or one of the cables have become disconnected if the drive is missing

If you check the drive cables and are certain they are connected correctly,it may be that the data cable is faulty and the drive controller may be at fault.And we cant overlook the fact that the drive itself may be bad.

DRIVE HAS POWER BUT WILL NOT READ DVD

First..try another dvd since a dirty or scratched dvd may not play.If the new dvd fail to play as well,check to see if the operating system is recognizing the drive

Click on My Computer and highlight the dvd drive.Right click and select properties.The statement "This device is working properly" should be present.If not or you see another message,try to update the device driver.

In the My Computer screen,highlight the dvd drive,and select the Properties screen,select Drivers,and then select update device driver.

Another cause may be the Windows Registry is corrupt. You can use software utilities such as PC Bug Doctor to repair your registry. Download this free repair utility at http://www.pcbugdoctor.com/download.html.

To make a backup of your registry with Windows 98, just go to Start, select Run, enter scanregw and click OK. This will run Scanregw.exe.

Restore your registry in Windows 98 by typing scanreg / restore at the Dos Prompt.You can also use.Winrescue XP at http://www.superwin.com/index.htm is a neat little utility for backup and restore of Windows XP.

The dvd drive or writer is an awesome storage and data backup drive.Use it to the fullest to enjoy music,video, audio,and more.Understand everything about this drive before something goes wrong.

Should your audio die on you,check the dvd to be sure it is not dirty or damaged.Look at the audio cable for signs of looseness.Inspect this cable to be sure it is inserted in the connector completely and that is indeed inserted in the correct connector.

If you have a dvd drive,take the time to visit the support web site and download the latest device drivers or patches to keep your drive running at peak performance.

So you have this great digital camera and you’ve taken lots of great photos. Now what Well you could go to a store and have them print your images for you, but isn’t that what you did with film The point of all this great digital technology is that you can print your own photos at home without having to pay someone else to do it. Here are some tips to help you get started:

1. It’ll seem like a lot of money at first but spend the money to get a good printer. Six color at least. Ink jets are wonderful for printing snapshots. You won’t need more than that. Also look around at the computer brands that sell computer packages for digital printing, the printer that they recommend is perfect for printing photos at home.

2. Buy some photo editing software. There are lots of brands out there many of them for pros but you can easily find software under one hundred dollars that will have lots more options than you will ever use. Look for software that has automatic settings so that the computer can automatically color correct, auto focus, brighten, or darken, etc. At least until you learn number 3.

3. Learn your equipment. Take the time play with the settings. Don’t try to print perfect photos right away. Most people with a little time and practice can learn to do basic photo special effects. Give yourself the time to learn.

4. There is one place that you are going to have to spend some money and it’s on paper. You can have a great image but unfortunately you cannot skimp on paper. Get the nice thick glossy paper, it’s worth it. I’ve tried the cheaper paper, which is good for test prints, but you need the high quality stuff for good prints.

5. DPI, dots per inch. Depending on your printer and your software you may be able to print up to 1200 dpi which is probably unnecessary for what you’re doing. For up to a 4 by 6 inch print you only need about 300 dpi. Most people cannot see the difference between a 300 dpi an a 600 dpi at 4 by 6 inches. For 5 by 7 or 8 by 10 you can go up to 600 dpi.

These steps will help you on your way to printing great digital photos at home. Remember though make sure that you have fun printing all those memories.

FYI Just so that you have a frame of reference, I’m a professional photographer and I have a six color ink jet that I paid less than $300 for and photo editing software that I paid less than $100. I print my 5 by 7 images for shows at 600 dpi.
