Around 13% of the population on earth is left handed. Many people prefer using their left hand for wide range of activities like using computer, throwing, eating etc. fortunately there are mouse designed for left handed computer users.   Before the establishment of left handed computer mouse, most of the left handed computer users have only had a choice of regular right handed computer mouse or ambidextrous mouse.  With the launch of ergonomic computer mouse, the computer mouse has changed its shape a lot. These types of mouse are usually shaped after the hand of the computer user.  So in this case if the mouse is designed for the right handed computer user then it can’t be used by a left handed computer user. However, after a long wait Logitech launched a special computer mouse for left handed computer users.

There are many left handed people who still use regular computer mouse for pointing on the computer and hold them in the left hand instead of right hand.  In such case, you can change the settings of the computer mouse and can change the button functioning.  Usually left click button of the computer mouse is clicked by the index finger as it is the most demanding and the index finger is appropriate for clicking mouse button.

Right click button on computer mouse is used less often and can be clicked with the middle or ring finger. Left handed people mostly operate mouse in such manner. However, in order to do this if you work with regular mouse, then you must change your mouse button function setting. You can use the left button as a right one and the other way round. If you don’t know how to change the mouse button setting then you can follow these steps – click start, then go in control panel and then select settings in the new opened window. Then go in printers and other hardware and click the mouse icon in the new window. You will see many tabs of options in the mouse window, but you need the first option i.e. buttons. Tick the option switch primary and secondary buttons and then you can enjoy computer working with left hand.  This type of setting can be applied to all regular and ambidextrous computer mice.

Here comes world’s first Voice Mouse or I must say voice computer mouse that follows voice command and works according to it. It just waits for your command and performs whatever you request.

First Voice Mouse was developed by an Israeli-American firm and has promised with a lot of new features to come in coming years. Voice Mouse is a device that is like a God gift to those people who have physical disability, like blindness or incapable to use hands. You can control movement of cursor comfortably. Using Voice Mouse is not a child’s play; its user has to make proper coordination of voice command and visual perception.

This hand-free navigation tool can be use to open files simply on voice. Voice Mouse increases your accessibility. Using Voice Mouse, user can write emails and can modify documents very easily. You can direct cursor of Voice Mouse to menus, toolbar buttons etc. You can also perform double click or right click using your voice as command. Qpointer a product of Commodios firm is powered by Microsoft speech recognition engine allowing its users to click any of the objects on computer screen through voice. This product is beneficial for those who suffer from paralysis.  With the help of Qpointer disabled people are also entering in computer field as there is no other way for them to use computer system. Voice Mouse is a complete solution for everyone who wants to be in touch to computers, but could not do so due to some handicap.

Voice mouse controls the pointer on screen on the basis of voice command given to it. Anyone can use it easily as it does not require complicated installation. The design of voice mouse was made based on the fact that the user should be able to produce simple voice command to perform certain operations. The system provides some basic interaction protocol and application specific protocols that allows user to operate voice mouse easily. In case of basic protocol, you have to choose four vowels that are A, E, I, O, U. Here each vowel is associated with direction of motion of pointer on the screen. In the same way combination of vowels as AE, AI, AO, EA tells about the pressure, the release and the click of mouse buttons to perform operations like double click and drag and drop. Association made between commands like (A, E, I, O, AE, AI…..) and events like pointer right, pointer left, pointer up, pointer down, click left button etc is done by user. Next protocol i.e. application protocol gets activated when cursor enters any particular area on the computer screen.  These protocols take user commands to perform certain actions that can be seen on screen. Suppose user describes window of any file or application in configuration file, now as soon as pointer enters in to that particular window application protocol gets activated. Using Voice Mouse, you can type words using virtual keyboard. So no need to type keyboard manually. All you have to do is give command to Voice Mouse to perform operations asked by its users.

Now let’s see what are the hardware and software requirements needed in order to use Voice Mouse. If you want to use Voice Mouse for your system you must have an Audio Card like Sound Blaster and one head mounted speaking microphone. And in software you need to have operating system either Windows 95 or WindowsNT. With these basic requirements you can have a voice mouse that can work wonders for you.

We all use computers every day and we all need to become familiar with as many important aspects regarding computer hardware components and software programs that we can use with our computers as well because otherwise we cannot actually use our computers properly and we will not be as efficient as we could be by gaining the knowledge and the necessary skills for using our computers and for improving their functions.

One important computer hardware component is the mouse which we all use every day and which we all know that it has been highly improved in the last few years. Numerous types of computer mouse devices have been made available on the market in time and this makes it possible for us to use the one that we might consider more appropriate for us to work with according to our preferences and to different factors that we need to take into account when analyzing such important devices.



In order to become able to decide which of these various types of computer mouse devices might be the most appropriate one for us to work with it is first of all important for us to become aware of these various types of computer mouse devices and afterwards to consider the main purpose in which we might need to usually use them so that we might take the best decision in the end.

One such type of computer mouse devices is represented by the mechanical mouse. When it is moved, the ball is being turned by it. Its optical encoding type of disks are known to present light holes and infrared LEDs are also included in it and they can be discovered to shine through its disks.

The second type of well known computer mouse devices is represented by the optical mouse. This type of mouse uses a light emitting type of diode as well as photodiodes in the idea of detecting the movements that are relative to the surface on which it is used. This is also the main difference in what concerns the way in which these two types of computers mouse devices, the mechanical and the optical one are known to function.

3D mice have also become more familiar among computer users in the last few years. The interesting thing about this type of computer mouse devices is that they do not need a specific surface on which to operate. Logitech and Gyration are the two most familiar computer mouse manufacturers who have designed interesting models of optical mice. Much computer mice have become familiar among computer users under the name of flying mice as well and they are known to function through ultrasounds in most of the cases.



These are some of the most important types of computer mouse devices that we can all find available nowadays and from which we can all choose to use the one that we might consider more appropriate according to our own preferences and needs.

When we have a computer or we are willing to buy and to have one it is important to be somehow informed about all the possibilities regarding the components of the computer, about which type of computer monitor would be better, which type of hard disk and software would be the best performing one and with which you would not have any kind of problems.

It might be useful for us to know what  type of speakers are better and offer a better sound quality, what type of keyboard and mouse are easier and comfortable to use especially if you are person who has to work a lot on the computer or you will stay a great deal of time in front of the PC because these elements are all very important.



It is obvious that you cannot know all the possible aspects and what type of element to choose from the beginning but you can ask for advice to the ones who have already used them and you can find  out if they had problems with them. If they did not have problems, it might be useful for you to know what type of features they present and of they were pleased with it. This way you can find a lot of real information direct from the best people and they are the direct users of the PC which are normal user like you.

It is also true  that opinions may be subjective in general but in the end we are all subjective so you cannot say that they are completely wrong. Now there is a trend in reducing the number of wires that are connected to the computer  and which can bother you somehow, it depends on the type of desk that you have, where the computer is placed and how the wires are hidden or where they are put. The most common wireless elements that have been used in the last few years are the keyboard and the mouse.  Many of the users have been very pleased because this type of products also enables them with movement freedom.

One of the better computer mouse devices from this point of view as well as in what concerns its price but also its quality and functions is the Logitech cordless click optical mouse;  because Logitech is a company which has very good products in this field of IT and computers. The mouse is not that expensive, it works  well,  it is wireless and also it is an optical mouse that moves very  well and the click system is comfortable to be used.

When it comes to technology, we have to admire and appreciate its efforts made to accommodate just about everybody. Actually, it kind of has to, in order to maintain a steady flow of customers. Somewhat special are the recent innovative outbursts of computer hardware designed for the physically disabled people. Just because most of us take for granted the easy access of our fingers and hands to the keyboard and the mouse, it doesn’t mean that it’s quite that easy, if at all possible for others.

Most people have heard of Stephen Hawking. He is suffering from motor neurone disease also known as amyotrophic lateral sclerosis (ALS) which, in time, practically paralyzed him completely. Up until recently though, he still could slowly and faintly move his fingers. A great mind like his was surely in need of a computer, but he had no motor abilities like us to help him use a keyboard or a regular mouse. Still, he was given an unusual mouse which was his only interface with the computer. The cursor on the screen moves constantly, and he only needed to click the mouse in order for the cursor to select a certain word.

It’s true. There a lot of people that are physically impaired when it comes to using even such a simple thing like the mouse. Just take into consideration a person who has no arms. Sure enough, technology has made it possible nowadays for such a person to get a good mouse experience using… their feet! The mouse has a rather different aspect (depending on the producer) but its functions and mechanisms are the same as the regular mouse.

There even are computer mice for disabled people that can function with just a slight touch of a fingertip. Using motion and pressure sensors, these mice record any slight movement of the fingertip and “translate” it to a more complex virtual movement on-screen. These kinds of mice have been invented and are a good option for people who suffer from paralysis. Using just that mouse a person can perform virtually any tasks on the computer. Of course, software developers had to come up with virtual keyboards and other virtual aids integrated in the operating system to help the physically impaired person.



Other, more interesting computer mice for disabled people use laser or radio waves technology. The mouse in those cases is practically a helmet on the head of the person that has a light beam pointed toward a receiver. When the person moves his head, the cursor on the screen moves accordingly to the signal of the movement processed after the receiver sends in the coordinates. It’s more like a remote control really, if you think about it.



Even a blind person can benefit from a mouse nowadays. The mouse is specially designed to have indented characters on its surface instead of buttons for clicking. There are also a wide variety of joystick computer mice out there. These help people with locomotor impediments (locomotor ataxia for example).

Next time you handle a mouse or use a keyboard, just take a second and consider that the fact that you’re healthy and can easily do these things isn’t something you should always take for granted.
