TYPES OF MOUSE
Douglas Engel Bert of the Stanford Research Institute invented the very first mouse in the year 1963. But later on the mouse underwent fast evolution.
The various tracking methods used in the mouse are as follows:
1. Ball Tracking Mouse
This ball tracking method has originated from the original track wheel mouse. It uses a ball and a set of rollers for the X and Y-axes for motion tracking. But now these kinds of mouse are not produced largely. This mouse is bulky and it provides average tracking performance.
2. Optical Tracking Mouse
These kinds of mouse are very popular now. It uses LED and a sensor to find the movement of the mouse and send the tracking information to the computer system. The performance of this mouse is better. They are very accurate in tracking performance for daily use. They have the capability to use most surfaces except transparent surfaces.
3. Laser Tracking Mouse
This is the latest type, and functions with the help of Laser. These kinds of mouse are popularly used in First Person Shooter (FPS) Games.
4. Red Ball Tracking Mouse
The Red Ball Tracking method uses a prominent red colour ball to reduce hand movement. It is designed in a way to save space and it requires only thumb and finger movement. These types of mouse are mostly used for drawing purposes as it has high efficiency and accuracy.
Apart from the tracking method, mouse can be classified on the basis of connectivity. They are:
(1) The Wired Mouse
Wired mouse utilize electric cables to connect to the computer. It uses the feature of PS/2 or USB interface. The optimum cable length of the mouse is about 6 feet. If used with a notebook the length may be about 2 to 3 feet.
(2) Wireless Mouse
For utilizing wireless technology, it is important to have a wireless receiver connected. There are lots of benefits by using the wireless mouse. It has no tangled wires. This wireless mouse works with a battery. But the life of the battery will be short.
(3) Bluetooth Wireless
The main advantage of Bluetooth technology is the capacity for long operation and high protection against interference. This wireless technology permits you to use the mouse in an operating range of up to 30 feet. But some of the exceptional models are able to provide an extended range of up to 60 feet.
(4) RF Wireless
RF (Radio Frequency) wireless technology provides an operating range of 15 feet. The recent development in RF wireless technology is 2.4 GHz RF standard, and it provides an extended range of up to 30 feet.
FEATURES TO CONSIDER WHEN BUYING A MOUSE
1. Interface
Most mouse now uses the USB and PS/2 Ports. But some older motherboards may have only PS/2port and no USB port. To use this connectivity the mouse has to be featured with a USB connector. Normally all notebook computers have at least one USB port. The main advantage of this USB port is hot swapping. Hot swapping is a process, which allows you to plug or unplug a mouse at any time while the system is functioning.
2. Buttons
Most mouse has at least two buttons and only one wheel for scrolling. More buttons in mouse can perform better. For example, the addition of back and forward buttons aid in the navigation of the web. There is software, which can be used to program the additional buttons that you want to have. It is easy to map more buttons to perform the copy and paste function.
3. Wheels
A wheel in a mouse can be used to scroll vertically in lot of applications like Mozilla Fire Fox, Internet Explorer and Microsoft Word. The recent advancement in the design of the wheel is a “Tilt Wheel”. This tilt technology allows you to tilt from side to side for horizontal scrolling. Some of the mouse has got two wheels. One wheel is used for scrolling vertically and other for scrolling horizontally.
4. Orientation
Hand Orientation is an important feature to be considered. The left-handers may pay attention to the hand orientation of the mouse. Mouse is usually designed for the right hand users. Generally symmetrically designed mouse are recommended for the left-hand users.
This was all about the different types or various forms of mouse available in the market, how they function along with the tracking technology and what features have to be considered while buying the device. Keep these points in mind when you plan to purchase a new mouse for your computer.

Mouse is provided with a button on its top front portion which is used by the user to click the options on the computer screen to perform an action. Mouse pointers are shaped like an arrow pointing towards the top of the display device. As the user moves the mouse, the pointer moves as a reference point.
The mouse needs a pad to place it over for smooth movement and it allows an optical mechanical mouse more traction. The mouse pad is commonly rectangular with flat cloth or plastic objects. The mouse sensitivity is the speed at which its pointer moves on the screen. If the sensitivity is more then it needs less effort and moves faster to get across the screen. But low mouse sensitivity needs more effort and moves slower. Mouse driver that is commonly included with the operating system enables the computer to communicate with a mouse.
A rare piece of mouse available in the market is the Foot mouse that enables the user to control the mouse with their feet. Cordless mouse operates a device without a wire that possibly will cause knotted movement. As it has no wire it requires type of device to broadcast a signal.

Mouse - An input device within your palm!
October 19, 2007
As everyone knows, mouse is a pointing device mostly used with computers. It uses unique technology to choose a menu or function in computers. With the support of two dimensional motions, it performs efficiently. A mouse has been designed with a small case. The case has been designed in such a manner to hold it comfortably. The case has 2 or 3 buttons. Mostly mouse come with wheels which is essential for executing system dependent operations. The movements of the mouse will be displayed on the screen as a pointer which usually resembles like an arrow mark.
• Oldest Mouse
The very first mouse was introduced in the year 1963. The first mouse was not small as we get now. The size of the oldest mouse was very bulky. They functioned with the help of 2 gear wheels. These wheels were fixed perpendicular to each other. The movements or rotations of these wheels were translated as motions.
• Mechanical Mouse
Gradually the size of the mouse started to reduce. External wheels were replaced by balls. The balls will turn around. The devices have two rollers namely X and Y. These grippers hold the ball which becomes a base for the physical movement of the balls. This types of ball mouse was used in 1972. The device can rotate in any directions with the help of balls. Instead of ordinary balls inverted track balls were used in the midst of 1980s and 1990s. Two rollers were housed inside the ball mouse. Each roller was equipped with the device for horizontal as well as vertical motions. The signals will be sent from the mouse to the computer with the help of wire connections.
• Optical Mouse
A unique technology has been used nowadays in designing mouse. A light emitting diode and photodiode have been used for detecting the physical movement of the mouse. An optoelectronic sensor plays an essential role in the performance of optical mouse. Chip is used for processing the changes usually happening among the frames. Today’s mouse manufacturers have designed mouse with the potential to process up to 1512 frames in one second. The major difference between mechanical and optical mouse is the detecting technology. Mechanical mouse use the balls to detect the movements optically. They were never bothered about the surface compatibility. But optical mouse use sensor light reflections to detect the motions.
• Laser Mouse
Mouse that functions with laser technology is known as ‘laser mouse. This high tech mouse was introduced during the year 2000. Logitech has the credit as "first laser mouse introducer" in the market. Instead of LED technology, IR laser is used which enhances the images. This laser mouse has an advantage of high surface tracking power and lower energy consumption. You can use wireless laser mouse but they are comparatively a bit expensive.
