Mice & Keyboards

Choosing a Mouse

All mice perform the same basic functionality needed to control a computer this being moving a pointer around the screen and allowing the user to select items. the differences between mice can be separated into 3 main areas. The type of connection to the computer, the buttons and how the mouse detects movement.

Connection types
Serial and PS/2 - These are used less and less often as old mice are replaced with newer USB and wireless models
USB - Most mice today use USB to connect to computers, even some wireless mice have a USB adapter to allow the computer to receive directions from the mouse.
Wireless - Wireless mice come in two basic types, RF and Bluetooth, some computers have built in Bluetooth and so Bluetooth mice do not need anything extra to connect to these computers, other wireless mice have a small USB connector to allow the mouse to send directions to the computer.

Buttons
The 1st mice only had 1 button and today Apple Mac's only need a single button to do most tasks mice with more than one button can be used with the additional buttons being assigned to different functions. All mice for PCs come with at least 2 buttons and newer mice come with at least a 3rd button or scroll wheel. Some newer mice have additional buttons that can be set to perform custom tasks such as previous/next web page or custom commands for your favourite game.

Detecting movement
The 1st mice used a small ball that turned when the mouse was moved, this movement would then be converted in to electrical signals and sent to the computer. Newer mice use light reflecting from a surface to detect when the mouse is moved with even newer mice using lasers which provide higher accuracy which is great for detailed work or fast paced game play, Logitech has released mice with Darkfield Laser Tracking™ which allows the mouse to work even on glass, which was a problem for mice previously.

Shape and size
Today mice come in many different sizes and shapes, it is important to find a mouse that you feel comfortable with, so that the mouse feels comfortable in your hand and is not to heavy to move, newer mice even allow you to adjust the weight of the mouse by adding and removing small weights so you can select the weight you prefer.

Choosing a Keyboard

All keyboards perform the same basic functionality needed to control a computer this being typing characters onto the screen. The differences between keyboards can be separated into 3 main areas. The type of connection to the computer, the feel of the keys and any additional keys it may have.

Connection types
PS/2 - These are used less and less often as old keyboards are replaced with newer USB and wireless models
USB - Most keyboards today use USB to connect to computers, even some wireless keyboards have a USB adapter to allow the computer to receive keystrokes from the keyboard.
Wireless - Wireless keyboards come in two basic types, RF and Bluetooth, some computers have built in Bluetooth and so Bluetooth keyboards do not need anything extra to connect to these computers, other wireless keyboards have a small USB connector to allow the keyboard to send keystrokes to the computer.

Feel of keys
The early keyboards were clunky and had to be pressed quite hard which made them hard to use for long periods of time, thankfully newer keyboards require less effort to use and so are gentler on the hands and fingers. there are many different types of keys but the main ones include the traditional spring type keys found in most modern keyboards, the calculator like keys that are a lot flatter and used for some laptops and some full sized keyboards and the other is keys made from rubber or some other plastic like material to give keys a rubbery feel, these keys are generally found in "roll up" keyboards.

Additional keys and key layout
Most keyboards use what is called the QWERTY key layout so called because the keys in QWERTY are next to each other. These keyboards are found most often but there are others available if you can find them. Other than the positions of the letters and numbers on a keyboard, the other symbols may be in different locations (or different symbols entirely) depending on the country the keyboard is designed for most keyboards in Australia use US or US International key layouts. Most keyboards have what is called a number pad on the side of the keyboard for fast entering of numbers like when using a calculator but other keyboards may not include these keys and so the keyboard is more compact, notebook keyboards often do not include these keys, or they are included but to use them the user has to hold down an additional key (called a function key, often shown as Fn on the keyboard) to activate them. Some keyboards are called multimedia keyboards and have buttons to control the computers volume as well as having shortcut keys to move to the next/previous song. Yet other keyboards have what are called macro keys, these are controlled by software and provide shortcuts to things like web browsers and email programs. More expensive keyboards have buttons that can be customised with the user's own macros and are ideal for gamming where you need a key to perform a complex action quickly, examples of these can be seen in the Logitech G series of Keyboards.

Shape and size
Today keyboards come in many different sizes and shapes, it is important to find a keyboard that you feel comfortable with and that has the keys you need and where you prefer the keys to be.

Additional features of newer keyboards
Illuminated keys - Some of the newer keyboards have illuminated keys which make them easier to see in low light conditions or for those with poor eyesight, Logitech have several different models with illuminated keys.
Macro keys - Some of the newer keyboards have what are called macro keys, these keys can be programmed to perform tasks the user wants to perform regularly, ideal for gamming.

Which mouse is right for me?

When selecting a mouse, you need to consider the differences above and select the mouse that meets your needs. If you are only after a basic mouse then most will be fine, however if you are after a mouse for a specific function, such as graphic design or gamming then you will probably want a mouse with higher accuracy and additional buttons or one that you can adjust the weight to make long use more comfortable.
