Optical Mice: The Fall/Winter Collection – THG.RU

Technological Considerations

The optical mouse has numerous advantages. Since it has no mechanical parts, it is almost impervious to wear and needs no maintenance. There’s no longer the need to clean the inaccessible wheels with Q-tips and rubbing alcohol. Furthermore, since its movement no longer depends on good contact, the mouse pad has become obsolete. The optical mouse illuminates the surface on which it moves, and an infrared optical sensor takes snapshots at regular intervals. A processor then compares these pictures with each other to determine the coordinates. Agilent Technologies, a spin off of HP, originally developed the process.

Quakers’ Complaints

The thing about mice is that they have to react immediately, especially for gamers, and especially for those addicted to Quake. If there is the slightest delay between mouse movement and the moment at which this movement is retransmitted to the screen, gamers will start complaining. The time lag is partly determined by the image correlation processing speed, which is expressed by the number of shots per second. This parameter also determines the ability of the mouse to follow very rapid movements without lagging behind or making mistakes in the coordinates.

If the first generations of optical mice were content with 1500 snapshots a second, this figure has improved drastically, although Saitek is still using the original Agilent process. Logitech has increased the speed to 2000 shots a second, and Microsoft has chosen to go even further, by offering a refresh rate of 6000 shots a second. They claim that this is the price to be paid for the ability to be able to move the mouse at top speed without any time lag or position error. It remains to be seen whether this really translates into better performance or whether it is just a marketing ploy.

Screen Resolution

Unfortunately, the refresh rate is not the only parameter that has to be taken into account. Resolution also plays a part. This is measured in dpi (dots per inch), and expresses the precision of the mouse. In fact, it is more correct to speak of cpi (count per inch) as Agilent Technologies does. Most of the latest optical mice are capable of 400 cpi, meaning that they transmit the coordinates 400 times per inch of movement. This figure implies two things: the precision and physical movement required. Let me explain.

The higher the resolution, the less the mouse needs to be moved in order to transmit the co-ordinates. The phenomenon is magnified, of course, in relation to the screen resolution. It is only on a screen of 1280×1200 pixels or more that the resolutions of the mouse becomes crucial. Microsoft and Saitek display a resolution of 400 cpi but Logitech is aiming to satisfy sharpshooters with 800 cpi. This is in some ways a response to Microsoft’s 6000 images a second. After all, optical-mechanical mice such as the Rasor can achieve a precision of 2000 cpi. Logitech claims that at a maximum screen resolution of 1600×1200, you shouldn’t be forced to repeat the mouse movement in order to get a response on the screen, although that is what you have to do with mice whose capacity is 800 cpi. Mice with a 400 cpi rating need to be moved further to achieve this. Remember, you can also adjust the speed from the Windows control panel within the limitations of the mouse and that the speed is reduced to 50% by default.

Logitech mice are actually too fast for me at this adjusted speed, and as this interferes with accuracy, I tend to reduce the speed. I’m not really convinced by this argument of the distance covered, but Logitech, like other manufacturers, also claims that the resolution has an effect on the general precision of the mouse and especially on quick movements, which would seem to be reasonable. The problem is that in an optical mouse, the two parameters of resolution and refresh rate are combined. I must confess that this is where my technical know-how runs out and I cannot possibly say whether it is the resolution or the refresh rate that is the most important, or whether it is a combination of the two and if so, in what proportions. If anyone has written a doctorate on the subject, please e-mail us immediately. It is probably reasonable to conclude that the refresh rate ought to improve the response time of the mouse and that the resolution ought to improve precision. This needs practical evaluation with gaming, and for once it should be done subjectively.

Area, Ergonomics & Features

Although an optical mouse does not need a mouse pad, it is not too happy with surfaces that are overly reflective. It goes berserk if you are using a glass or black-lacquered Formica surface. Having said that, all the mice used in this test were extremely tolerant and will work on almost any surface. Even a sheet of white or black paper is no handicap. If a problem arises, all you need to do is dig out your old mouse pad. In any case, we advise you to use a mouse pad for game-playing as a general rule because the mouse glides more smoothly over a mouse pad and takes less wear and tear as well.

The shape of the mouse is also an important factor in its performance. If it is shaped to the palm of the hand and comfortable to use, your hand won’t get tired, even after extended use. As for the other features, most mice have additional buttons because all optical mice are supplied with the scrolling wheel, which is now standard. The additional buttons can be easily assigned using the software supplied by all manufacturers. Having said this, if you don’t use them, don’t install the drivers because they could create a conflict or slow down the mouse. Windows Millennium, Windows 2000 and Windows XP recognize all the mice we tested automatically. Under Windows 98, you may need to resort to installing the driver supplied with the mouse.

Connection

All the mice in this comparative study use the USB port, and that’s a good thing, not only for plug ‘n’ play but for precision as well. The USB port enables 125 data exchanges per second. The speed of the standard PS/2 port varies, depending on the operating system used, from 40 to 60 data exchanges per second. Of course, the PS/2 port can be sped up by installing utilities but they take up CPU time. So even though Logitech and Microsoft supply PS/2 adapters, don’t run the mouse from the PS/2 port or you will slow it down.

Logitech Innovations: Greater Precision

All the new Logitech optical mice are now equipped with a sensor that captures 2000 shots a second with a resolution of 800 cpi. We therefore began by comparing this upgrade with previous models. This was easy because the plain Mouse Wheel has not been modified in any other way. As I explained in the technological introduction, the shortest physical distance for moving across the screen at high resolution does not seem to me to be a significant factor. Precision and reaction time are another matter. In a first-person action game there is a significant gain in precision. You can, without a doubt, target things more accurately and quickly. Personally, I had no problem with the reaction time of the first generation of sensors, so it’s hard for me to get excited about the even greater precision of this new mouse. On the other hand, I have experimented with both mice at top speed, playing First Person Shooters (FPS) fast and furiously, and my impression of greater precision was indeed confirmed.

Operating Software

Logitech is now delivering mice with new software for programming the buttons, and this is useful if the mouse has more than two programmable buttons. One might be tempted to say that you can forego using the software if Windows recognizes your mouse. But for once, there is a little plus that won me over. You can use the software to install a really cute WebWheel function. When you are in a browser and you push the knob, a small wheel appears on the screen, displaying the most frequently used functions, such as “update” or “previous page”. All you need to do is move the mouse in order to select a function then click to confirm. It’s easy and efficient! Of course, Logitech takes advantage of it by making it a portal for its own website, but that’s no big deal. In fact, I ought to suggest that they include a link to Tom’s on their WebWheel!

Logitech Wheel Mouse Optical SE (or not)

Logitech’s standard optical mouse is equipped with 800 dpi technology that they have dubbed “X2”, and it’s now available in metallic red for a more striking appearance. The SE only refers to the color, because the blue model currently on sale without the “SE” is also equipped with the new technology. So you can choose the color according to taste. Just be sure that “X2” appears on the package to avoid confusing them with the previous generation of mice. The mouse has a classic shape and is comfortable for both right-handed and left-handed users. The proportions are just right for all types of hands. It has no bells and whistles, being content with two buttons and a knob, all very easy to activate. Personally, I find this mouse ideal for playing a FPS. It isn’t too bulky or too heavy, the perfect weapon, in fact. Furthermore, its precision and reaction speed are excellent, so the price of $26 is justified.

Logitech Cordless Optical Mouse

After being the first manufacturer to bring out a cordless optical mouse, Logitech is at it again with this simpler and less expensive device ($40). Typical of Logitech mice, the connection is made via radio transmission. All you need to do to install it is insert the batteries into the mouse, connect it to a USB port and make the link between the base and the mouse by pressing the Connect buttons. The shape is classic, comfortable for both right-handed and left-handed users. It is also less bulky and lighter than the other cordless optical mice. This makes it more suitable for gaming and especially for FPS. Unfortunately, the radio link reaction time is not fast enough for this type of game. When you are moving very quickly and stop suddenly in order to aim, you may find that you are not that accurate. This only applies to Quake enthusiasts and Red Faction players. In the case of a slower FPS and other strategy games, it is absolutely no problem.

On the other hand, the absence of a cord has lots of advantages. The batteries also last for a long time – Logitech uses several energy-saving strategies when the mouse is not in use. This is no problem for the user because as soon as the mouse is moved or clicked, it starts up again immediately. Since the energy management function is the same one that we have been using for ages, we can estimate that the batteries will last for about two months when used intensively for 10 hours a day, and thus confirming the claims made by the manufacturer. The general ergonomics are excellent and the buttons operate smoothly as does the scroll wheel. This cordless model has every advantage: precision, good ergonomics and a reasonable price.

Logitech’s Dual Optical MouseMan

Logitech decided to go even further with product improvements by integrating a second optical sensor in this mouse. Both sensors work together; if the first one finds itself missing data the second one takes over and vice versa. Logitech claims that this makes the mouse less sensitive to different surfaces and that it improves accuracy because it’s never in a situation where data is lacking. In fact, the Dual mouse can be used on any kind of surface – even a translucent grey plastic folder with a slightly raised grid pattern on the surface did not hinder its performance, although its rivals threw in the towel.

That being said, once can’t expect miracles – it failed to work on a mirror. But anyway, who would want to use a mouse on a translucent folder or on a mirror? And that’s where the problem lies. The other mice work perfectly well in almost all cases, so why invest a penny more in this technology? The answer is: because it responds faster. Although I have found that there’s nothing more accurate than the Wheel Mouse in graphics applications (e.g. Photoshop for Windows), in FPS situations it is a huge advantage. It moves with exceptional smoothness and repositions itself to a fraction of an inch after long movements. This is the Logitech mouse that Quake fanatics will want to use. On the other hand, its fairly large, sloping shape is exclusively designed for right-handers. The shape is very ergonomic for general use but is a bit bulky for action games. The buttons and the knob have a smooth, light action and move exceptionally well. The third button on the left is easy to reach and can always come in handy. Furthermore, at a price of $49, it remains fairly inexpensive.

Microsoft Innovations: Ergonomics And Speed

As I mentioned in the introduction, Microsoft has improved its optical sensor, especially the processor that goes with it, so that it now takes 6000 shots per second and, according to the manufacturer, this ought to guarantee zero time-lag, something that FPS players will appreciate. The resolution has not changed, however, remaining at the standard 400 cpi. As in the case of the Logitech mouse, we began by comparing two identical models, the Optical Intellimouse, whose new version differs only in the new sensor. Genuine progress has been made, the mouse really does respond better. When playing Counter Strike or Red Faction, it gives the impression of being more effective in situations where a quick sweeping motion is called for, followed by a sudden stop to aim accurately. Our Quake-playing testers unanimously approved this new development. There really is no time lag and the precision is excellent.

Then we compared the new Microsoft technology with that of Logitech, alternating between Intellimouse and Wheel Mouse. First of all, it should be said that both mice did well in their FPS trials. With regards to performance in very fast games such as Red Faction, the Microsoft mouse took the lead, but the Dual Optical Mouse is generally just as good, so deciding between the two is simply a matter of personal taste. Microsoft mice are more sensitive, but the Dual Optical moves more smoothly.

The driver that is bundled with the Microsoft mouse is in version 4 and lets you easily program the buttons. If you don’t want to use buttons 3 and 4, don’t install it.

Microsoft Optical IntelliMouse

This is Microsoft’s basic optical mouse and it has a number of advantages. The shape is suitable for both right-handers and left-handers, and its grainy coating is very comfortable and prevents sweaty palms from slipping. The position is natural and the proportions fit all sizes of hands. The buttons and knob are easy to operate. The shape is particularly well suited for FPS, and the four programmable buttons are by no means superfluous. As with Logitech’s Wheel Mouse, make sure that the words “6000 images per second” appear on the packaging to avoid buying an older model by mistake. At $20, it is quite expensive but well equipped.

Intellimouse Explorer 3.0

This first optical mouse made by Microsoft has been completely overhauled. The initial version was too cumbersome but this one has perfect ergonomics, though solely for right-handers. This mouse is not small but it is so comfortable that it seems like an extension of the hand when playing action games. The four buttons are exceptionally accurate and easy to operate, as is the knob. It is also perfectly balanced in its distribution of mass. If you are right-handed, then this is clearly the most ergonomic and least tiring mouse to use out of all those tested here. Combined with its new sensor, the Explorer should satisfy even the most demanding users and especially FPS fans. The price of $47 makes it a bit expensive for a second-generation mouse, especially when compared to $49 for Logitech’s Dual Optical.

Intellimouse Wireless Explorer

This has got to be the ultimate mouse, or close to it. Not only is it cordless, but no installation is required, either. You just plug it in and it works with a base station that can be placed three feet away without reception problems. Transmission is via radio waves. Two batteries power the mouse and the manufacturer promises that they will last for four months, using advanced energy-saving technology. In fact, it detects the presence of your hand and starts up as soon as you use it. However, in practice there is sometimes a short pause, but you get used to it. We haven’t had to time to check how long the batteries last, of course, but even if they only last two months like Logitech’s batteries, that is perfectly acceptable.

The ergonomic shape is designed for right-handers exclusively, especially those who don’t have massive paws. As soon as a device reaches the optimum in ergonomics, it becomes less usable for those at the extreme ends of the spectrum. On the other hand, no pun intended, right-handed people whose hands are not overly large will find it as comfortable as can be. Despite its rather large size and the weight due to the batteries, it fits naturally in the palm of the hand and can be easily manipulated without ever tiring the user. The four buttons and the knob can be operated smoothly and precisely. Furthermore, it benefits from the same technology used by other Intellimice, so no worries on this score. It is thus the perfect mouse, or rather it would be if it didn’t cost $65, which is quite steep. Furthermore, like the Logitech models, the cordless mouse does not convince me as being the best device available for playing FPS and other high-speed games such as Quake or Red Faction. I find the response time to be slower than with a conventional mouse.

Saitek’s Asset: Originality

Saitek has entered the optical mouse market more recently, along with the second wave of manufacturers. This British maker still uses first generation detectors and 1500 shots a second, with a precision of 400 cpi. I would therefore recommend a Logitech or Microsoft mouse for Quake-players. However, as mentioned earlier, this recommendation only applies to extreme FPS multi-player situations, so most users won’t notice the difference. Saitek mice are neither more nor less sensitive to different surfaces than the Microsoft and Logitech versions. On the other hand, the least that can be said is that the range is original.

Saitek Optical Mouse Pro

This mouse is visually striking, looking somewhat like an escapee from a sci-fi series of the Star Trek New Generation type. It’s in your face, lit up in blue, a whole new ball game. The mouse is designed for use by left-handers as well as right-handers and fits comfortably in the hand initially, but the back isn’t rounded and becomes slightly awkward with intense use. Furthermore, although the material itself is pleasing to the touch, the assembly looks cheap, and the joints and edges tend to make cracking noises when under pressure. This is a subjective remark and probably does not affect the overall solidity of the device. The two buttons are easy to operate, and the knob is quite firm but not annoyingly so.

As an added value, Saitek has equipped it with an amusing function, activated through the software supplied – the mouse alerts you when an e-mail has arrived by flashing. It flashes slowly for a normal message and quickly for an urgent message. This function operates independently of the navigator and is an upstream function, which means that once the e-mail arrives in the in-box, it no longer flashes. So this is of no use unless you check mail at regular intervals. It’s up to you to decide whether this rather gimmicky function could be of interest. If not, the driver merely uses the standard Windows interface. To summarize, the Optical Pro is not a bad price ($40), but considering that it is the same as Logitech’s Wheel Mouse, this seems a bit costly.

Optical Force Key

Logitech found its vibrating mouse to be more of a white elephant than a mouse, but that has not stopped Saitek from regressing and asking $15 extra for the additional vibrator function. Apart from this, it is exactly the same mouse as the Optical Pro. Let me remind you of the principle of tactile mice. This process was developed by Immersion and makes your mouse vibrate at varying degrees of intensity and speed. You may even feel it give a little jolt or hiccup. The idea is to enable you to feel objects or get some physical sense of them using a virtual 3D relief effect.

At first, it’s quite fun to visit a site that claims to demonstrate the technology. You click on an engine and feel it starting up. It offers tactile sensations which, combined with the vibrations, gives you the impression that you are really moving your mouse over pebbles or a grid. Once the novelty has worn off, however, it’s time to find applications for it. You could sensitize your Windows desktop, for instance. Another negative is that this is not yet available in the US market, but you can check through Saitek’s Web site for local availability.

Pull down on a window and the vibration gives the impression of resistance. Pressing a button gives a jolt of awareness of its physical existence. Here again, you may find this amusing at first, but I can assure you that after half an hour you will only be interested in one thing – urgently unplugging the vibrator, which fortunately is an option. In the end, there’s only one suitable use for it: gaming. In a strategy game, if you can “feel” the units or the terrain you may be able to operate the mouse with greater accuracy. Unfortunately, there is currently only one game, Black & White, which can generate these effects. And even here, after playing it for an hour it will begin to wear on your nerves, just as when you use it under Windows. So it is only a useless gimmick, and one that costs $54.

Saitek Wireless Optical

Like Logitech and Microsoft, Saitek’s cordless optical runs via radio transmission. It is extremely conventional in shape, which is a stark contrast to the rest of the products manufactured by this firm. In fact it is quite conservative, and even dreary, but oh well, there’s no accounting for taste. Saitek chose an original method of powering it, however. The mouse has two small rechargeable batteries. The problem is that they need recharging, and so you will eventually find yourself with a mouse on the end of a cord again. The charger consists of a miniature plug at the end of the cord, which has to be plugged into the side of the mouse. Not only is this impractical but the connection looks like it has been put together ad hoc.

But that’s not all – the base unit needs to be really close by. As soon as you move it more than a foot (30 cm) away, the connection becomes problematic. Add to this a rather cumbersome installation procedure and you will soon realize that I am not exactly enraptured. Furthermore, although the mouse feels fine in the hand, the buttons are much too stiff and you will get a cramp in your fingers if you use it in an action game. Quite honestly, this mouse is not a great buy.

Summary Table & Conclusion

For wealthy right-handers, whether or not they like playing FPS games, I would recommend the Microsoft Explorer 3.0 mouse, which has exceptionally fast response and is absolutely comfortable. Otherwise, the Logitech Dual Optical is also comfortable to use and offers optimal precision and smoothness as well.

For wealthy left-handers and Quake-players, the Intellimouse Optical by Microsoft is the best choice. It has easy contours, an excellent grip and an immediate response. The two extra buttons could be useful for games.

Finally, if you are looking for a simple mouse that is accurate and not too expensive, go for Logitech’s WheelMouse Optical SE. It is equally suitable for the right-handed and the left-handed, and its metallic coating gives it a pleasant look and feel.
