How long can you sit at your computer without hurting? Thirty minutes? Sixty minutes? Sitting for prolonged periods with poor body positioning can be very fatiguing. Over time, the fatigued area becomes strained and pain sets in.

With a correctly configured workstation you should be able to sit for hours without hurting your back, neck, arms, or wrists. Below are the recommendations I give my patients to help them achieve correct ergonomics or body positioning.

Choosing a well-designed office chair is an essential step in achieving good computer ergonomics. A good chair will preserve and support the natural curves of your back. In the neck and low back the spine curves in, and in the middle back the spine curves out. To perform well the contour of the chair’s back should match the curves of your back. (See the “Good vs. bad computer posture” drawing by clicking on the link in the resource box.) This support keeps you from slouching when you sit.

A taller seat back is better than a shorter one. The lower portion of the seat back should support your lower back’s inward curve, and the upper portion should support your middle back’s outward curve.

Sit all the way back in your chair so the seat back can do its job of supporting the curves of your spine.

A good chair must be well padded. I’ve seen trendy “mesh” chairs in office-supply stores but have never found one that was satisfactory. Mesh chairs are too stiff and hard. Nothing beats old-fashioned foam padding in a chair. The seat cushion should fit your body and be well padded.

Your legs should be parallel to the ground; and those with short legs may need a footstool. A chair that reclines offers a good change of position that can help prevent fatigue. Reclining allows you to change positions and still receive the support of a well-contoured seat back.

Once you have a properly supporting chair, you can turn your attention to the desktop.

One of the most common computer workstation errors is poor monitor placement. A correctly positioned monitor will help you to avoid neck and shoulder pain. The ergonomic principle here is to keep your head and neck in a neutral position: This is accomplished by looking straight ahead. You don’t want to look up and down, and you don’t want to look left and right.

You keep your head from looking up and down by keeping your head and eyes level. This is accomplished by raising the computer monitor so that your eyes hit the screen three quarters of the way up (See the graphic in the resource box.) A level head keeps your neck muscles from having to constantly contract to hold your head in a poor position.

You keep your head from looking left and right by placing the monitor directly in back of the keyboard. This avoids the common practice of placing the monitor off to the side. This side positioning causes your neck to …

The computer mouse is a very essential tool in how you navigate and operate your PC, which means that if this device grinds to a halt then a problem arises, so take the time to fix it. Many USB mouse problems can be easily solved with a few simple steps:

One, clean the mouse

USB mouse can cause trouble when its parts get dirty or grimy. If your device becomes to stick, you need to clean it. For a roller mouse, take the mouse apart, clean the ball with mild soap and warm water, clean the internal rollers carefully with a cotton swab dipped in rubbing alcohol, and let them air dry. For an optical mouse, you can use a cotton swab dipped in some rubbing alcohol to clean its “eye” on the mouse bottom and let it air dry.

Two, replace the broken parts

Sometimes if the mouse cursor moves ineffectively, maybe some part like the switch in your mouse is broken, so swap it with another new one and test.

Three, change the speed of the mouse tracking

If the mouse pointer is too slow or too sensitive, try the following steps:

Step 1 Start – Control Panel – Mouse

Step 2 choose the Pointer Options tab

Step 3 On the first section of this box, you can see Select a pointer speed, and adjust the slide bar there to change the speed of the tracking.

Four, check the connections

Because the pointing device is constantly being used and moved, it can occasionally be unplugged from the computer. If your mouse can not be detected by your computer or it stops working from time to time, you need to make sure the cord and the USB port are both in the good-working condition and the cable is securely plugged into the USB port.

Five, install mouse drivers

If cleaning and checking the mouse doesn’t work, you may need to reconfigure the mouse driver. Try to uninstall and reinstall your mouse driver or download a driver tool like <a rel=”nofollow” onclick=”javascript:ga(‘send’, ‘pageview’, ‘/outgoing/article_exit_link/3065578’);” href=”http://www.pcdriverhelper.com/Mouse.html”>Driver Helper</a> to help you perform it automatically.…

A few years ago 5.1 surround sound DVD video players looked likely to become standard kit in every living room in the technology friendly world.

So now a few years on, what has happened to the original promise of surround sound music? Well the answer to that is ‘lots, but not nearly enough.’

For those that don’t know already, 5.1 surround sound is basically five speakers and a sub-woofer placed around your room allowing you to listen to music or a movie soundtrack literally surrounded by speakers. The film industry pioneered it for theatres and it then became available as a DVD player add-on for home entertainment systems.

Now at least 100,000,000 people world-wide own systems, which can and should be used for all manner of surround sound music DVDs.

I hear you say, ‘but surround sound music on DVD hasn’t really caught on. All that wire in my living room’.

Even though the consumer can buy a DVD player and surround speaker system cheaply enough, surround sound music hasn’t really caught fire yet. Why?

There are reasons why we should all remain confident that surround sound music will become more popular, but at the moment it’s still an infant child.

The amount of different DVD and surround sound formats is confusing and can be offputting.

The consumer desperately wants an end to the confusing compatibility war between different surround sound formats.

Many music artists would start producing DVDs if it wasn’t so complex, just as there are many consumers that would purchase a surround sound DVD system for the same reason. They should be able to buy a DVD player and play any product claiming to play DVDs.

Consumer surround sound formats currently include sound on video DVDs encoded as Dolby 5.1 surround sound or DTS; the competing DVD-Audio (DVD-A) and Super Audio CD (SACD) formats and MP3 Surround.

There are 5.1, 6.1, 7.1 systems, four speaker systems, even one speaker systems and ‘simulated surround sound systems.’ Phew! See what I mean?

They all have their uses, but the I feel the music business would be wise to embrace one format. Every time the consumer buys a surround sound music product they have to research whether it will be compatible to their particular system.

The good news here is that slowly, but surely things are improving. As long as there is no ‘new’ new format to rock the boat, the problem of incompatibility could become a thing of the past.

There are many great web sites to visit which do explain (in as much detail as you could possibly imagine) all the different formats and help you decide what to buy.

How about all that wire in my living room though?

There are wireless speaker systems available, but the cheaper ones are for mainly rear-channel wireless amplification. This doesn’t quite get rid of all the wires and limits people who have odd shaped rooms. But they are better than nothing.

It would be great for a ‘let’s make it …

Yes, it can be done. In fact, many gamers and HD video enthusiasts use LCD TVs instead of standard PC monitors to views movies from their Home Theater PCs or HTPCs. 32″ LCD TVS are quite common among HTPC users as they are a cross between the more preferred 42″ plasma TV and the more modest 22″ LCD computer monitors. But 42″ high definition LCDs are getting mainstream and they can likewise be used as PC monitors. There are certain things to consider though.

– First is the fact the LCD TVs are basically derived from LCD PC monitors but enhanced and specialized to display movies that can rival Plasma TVs. The characteristics for a good high definition display on LCD, like high contrast ratios and response time used to be an issue as they were inferior to that on Plasma. But the newer LCD TVs and monitors have evened out the Plasma edge in the 42″ screen sizes and below. Plasma still reigns supreme above that size though LCDs are catching up.

– Because of higher dot pitches, you need to set the PC video output to match the LCD TV’s native resolution in order to display readable fine texts. This ensures exact pixel mapping between the computer and your display. Full-HD means 1080p resolution while HD-ready means either no digital tuner or 720p resolution. It is strongly recommended that you stick to 1080p resolution even for 32 inchers as pixel density is higher and allows a more comfortable reading of displayed text if you are going to use the LCD TV for word documents and spreadsheets. Bear in mind that for any given resolution, you get looser pixel density the bigger the screen size is.

– Consider your viewing distance. Typically, you would be seated 1ft – 1.5ft away from a monitor screen 15″ – 22″ in size on a regular computer table. With a 32″ LCD TV, you will need to seat farther back at around 2.5ft – 4ft away to have a better view of the entire screen. Check to ensure that your computer furniture can accommodate this. Otherwise, you could be running your face right smack on a large 32″ panel.

– Connections between the LCD TV and you PC can be problematic for certain LCD models. The problem starts with HDCP technology which is a security hand-shaking protocol that all 1080p LCD TVs now have. If your PC video card is not HCDP-compliant and your LCD TV is, you will not be able to view Blu-ray movies which have HDCP compliance built into the software when using HDCP-compliant DVI or HDMI connection. In addition, it is possible that the LCD TV will not display anything if it cannot verify that the signal it is receiving has HDCP. Either you get a blank display or the LCD TV automatically downscales its resolution to 720p or lower. To be safe, make sure the LCD TV you’re getting has at least a VGA terminal so you can …

The computer monitor or visual display unit is the device that displays information that the computer program presents to you. It is your eye into the computer. There are three types of monitors; the CRT (Cathode Ray Tube), the LCD (Liquid Crystal Display), and the Plasma Display. The CRT is the oldest technology; it is your old large TV tube and is being replaced by the LCD and Plasma displays. The Plasma display is more expensive and heavier, therefore lending itself to situations that require much larger displays. 

The LCD display is what you see when you look for computer monitors at the store. This is the most popular display technology nowadays. You will have to consider the specifications when selecting a monitor. The specs you should be concerned with are; the width, resolution, brightness, contrast ratio, response time, the interface, and the viewing angle.

The width is the first item you look at when selecting a monitor. The question you ask is; how big a monitor do you want? The width is measured diagonally from opposite corners. Also, think about the viewing area, sometimes there is an unused area at the edge of the display.

Resolution refers to the quality of the picture. How small are the details that you can see. This is determined by the pixel size, as well as the pixel pitch. A pixel is the smallest piece of information in an image. You will have better resolution with a smaller pixel size. The pixel pitch measures how many pixels per inch. Again, you will have better resolution with a larger number of pixels per inch.

Brightness is the amount of light that is emitted from the monitor. Think about viewing the monitor in a darkened room, and then viewing the monitor in bright sunlight. Where will you see the picture better? Which display works better in a well lighted room? You begin to see that the display with the greater brightness has the advantage. Brightness is measured in nits or candelas per square meter. Looking at the retail offerings you see that many monitors have 300 nits of brightness. This is good for most applications.

Contrast Ratio is the ratio of the light emitted by the brightest color (white) to that of the darkest color (black). The higher the ratio the clearer you see the image.

Response Time is the amount of time a pixel in an LCD monitor takes to go from black to white and back to black again. It is measured in milliseconds (ms). Lower numbers mean faster transitions and less ghosting.

The Interface is the connector and cable used to connect the computer monitor to the computer. The LCD display can use an analogue VGA connection or a digital interface like DVI, HDMI, or DisplayPort. DisplayPort is not readily available at this time.

The Viewing Angle is the maximum angle at which a display can be viewed with acceptable visual performance.

iPhones, PDA’s and bank kiosks all have touch screen panels that are used everyday, all not requiring computer mice. Since touch screens are becoming more and more everyday tools, it’s not surprising to think that perhaps someday the computer mouse we all have come to depend on will be obsolete. What will we all do with the world’s enormous supply of plastic computer mice? Here are just a few suggestions.

     
  • Paper weight

If in fact the computer mouse becomes obsolete, everyone will have one that they don’t need or use, but perhaps they can be used for something. A computer mouse would make an efficient paperweight to secure paper and files sitting on your desk if you happen to be sitting next to a window or strong air conditioning.

 

     
  • Nostalgic Christmas Ornament

Okay, so someday, generations later when the computer mouse is all but a funny memory, you will be able to keep its memory alive by holding onto one of these once-precious tools and tie a red ribbon to it for decorating your holiday tree. The computer mouse usually is a shiny and attractive piece which people may even mistake for a precious ornament you cherish.

 

     
  • Bronzed Piece of Art

Since your computer mouse will likely be in a museum some day, get a head’s start on making your computer mouse legendary by dipping it in gold, bronze or even spray paint to give it that museum quality look. Place it on the mantle, on a pillar in your office or hang it on the wall. Even if people snicker, they will admire the lengths you went to display an old friend you once knew so well.

 

     
  • Game Piece

Since there will be a ton of computer mice sent to the recycling center, why not collect them and recycle them in another way like making them useful again. Instead of the car or thimble piece in Monopoly, use a computer mouse as your piece. Use the computer mouse in any game that requires pieces really, or perhaps invent your own game using computer mice as pieces. Paint them, place stickers on them or dust them in glitter for a fun gaming piece that will no doubt make your piece stand out above the rest.

 

     
  • Decorative Wall Designs

While you are at that recycling center picking up old computer mice for game pieces, pick up a whole lot more for decorating an entire wall of your house for a cool look. Give the futuristic look by using a product from the past. Your guests will marvel at your creativity and think of you as the ultimate environmentalist. You may even start a trend in computer mice décor.

When touch screen panels take over your life and the computer mouse no longer serves it’s purpose, give it another chance to be useful again. Think of it as going “Green,” or being practical, however you want to call it, the end doesn’t have to be the recycling pit …

Portable music has come a long way since the days of the walkman in the 1980s. The walkman, popularized by Sony, allowed music addicts to travel with their favorite music in cassettes wherever they went as long as they had enough batteries to keep the device running. Then the walkman met its nemesis, the Discman, also released by Sony although Phillips electronics was the brains behind the switch from cassette to compact disc. Compact discs or CDs, introduced studio sound music to the public and music quality has never been the same again. But CDs are also cumbersome and large and therefore had to store. They are also not friendly to extremes of temperatures and can be scratched and easily damaged just like the prehistoric vinyl 12′ records of the 60s and 70s. To counter this, Apple Computers invented the iPod which at this point is the ultimate in portable music and video.

The iPod boasts a huge memory capacity and therefore the ability to store, not one, but hundreds of CDs! This means that instead of traveling with a bagful of CDs and cassettes, one can easily download their entire music collection in digital format to their iPod. One can therefore walk or travel or jog or go camping with a small portable iPod containing thousands of songs.
Recently, Apple came up with portable speakers for the iPod. These are hugely popular because instead of one person listening to their music using their headsets, more than one person can enjoy quality music or podcasts. This can be highly ideal especially for college students and study groups who need to listen to podcasts.

When shopping for iPod speakers, there is as wide an array as there are manufacturers. This is because other than the regular household names’ consumer electronics manufacturers, there are many other manufactures who have capitalized on the rise of the iPod and are now creating speakers and other accessories. When discussing the best speakers, we need to examine the need. Some people’s usage is more than others. The brands that are currently hot in the market right now are Logitech, which is a respected computer speakers and accessories maker.

For anywhere between $90 and $200, you can find decent Logitech iPod speakers which boast quality sound. Altec Lansing is another company that has gained a name for itself especially when it comes to speakers. Altec has also been manufacturing car stereo speakers for a while and they therefore have the experience to back their quality. A pair of iPod Altec Lansing speakers will cost you around $150.00 although the same company also produces more costly iPod speakers called the InMotion i600 and the Pure-Fi Dream which can run you close to $200.00. The Chestnut Hill Sound George have also gained renown due to their exceptional sound quality but these can range about $500.00 and are therefore on the pricy side. iPod speakers are definitely here to stay and anyone serious about transforming their musical experience should invest …

This article will explain how to connect your PC to a Big Screen TV, and experience the ultimate in HD picture and HD sound, using the existing PC outputs. 

The set up is actually very simple, and will most likely only require an additional minimal purchase of an HDMI cable to connect the PC to the big screen.  The HDMI (High Definition Modular Interface) cable will carry both HD sound and picture to your Big Screen TV.

Before you begin, you will need to verify that the Motherboard on your PC has an outlet to plug in a second display.  Most of the newer motherboards contain both VGA and HDMI outputs on the same board.  You will also need to verify that your Big Screen TV has an HDMI input.

To complete the installation, first install (1) end of the HDMI cable into the HDMI output on the back of the PC.  Plug the other end of the HDMI cable into the HDMI Input on the big screen TV.  Then, configure your PC for using dual monitors.  To configure your PC using the MS -Vista OS, Click on the  Vista Start Logo, Click on Control Panel.  Click on Personalization, Click on Adjust screen resolution.  You should now see the Display Settings window with the existing computer monitor (labeled 1), and a second smaller monitor(labeled 2).  Located immediately below the monitor icons, you will see the drop-down selector box with both monitors listed.  By default the number (2) monitor will be the Big Screen TV.  Immediately below the selector, check the (2) boxes, This is my main monitor, and extend the desktop on to this monitor. Click OK and Close the window.

Now for an example, resize your I.E.  browser window, so it is about half the size of your computer screen.  Grab the top of the browser window, and drag it over to the other monitor.  After dragging the window, you should now see the I.E. browser window open on your other screen(Big Screen TV).

Now the fun part!   Go to one the new free movie sites like,  HULU, and now you can watch the show on your Big Screen TV courtesy of your PC.

The office chair was strategically designed to amplify productivity of clerical employees by making it possible for employees to remain sitting at their desks for normal than long periods of time.

Back in the mid 1800’s businesses began to expand the traditional model of a family business with little emphasis on administration. During this time office work was expanding, an awareness of the office environment, technology and equipment became part of the cultural focus on increasing productivity. This awareness have rise to chairs specifically designed for administrative employees, along came the office chair.

A swiveling chair with caster wheels allowed employees to remain sitting and yet get to a number of locations within their operational area, thus eliminating the time and energy expended in standing. A wooden saddle seat was designed to fit and support the body of a seated employee and the slatted back and armrests provided additional support to increase comfort. Like our modern chairs, many of these models were somewhat adjustable to provide the maximum comfort and thus the maximum working time.

The Ergonomic chair is an alternative to traditional office chairs; the ergonomic chairs generally take a little getting use to, but usually become very comfortable over time. Then Ergonomic chair is very beneficial for people with lower back pain or discomfort.There are three types of Ergonomic chairs:

The Kneeling chair has no back and places the employee in a modified kneeling position. The design encourages good posture by sliding hips forward and alignment of the back, shoulder and neck.The Saddle chair can be used as either a desk or computer chair. Shaped in the shape of a horse’s saddle and puts the user in a position similar to that of riding a horse.The Exercise chair is shaped like a ball and is large enough to support a user in any long-term sitting usage. …
