What is Mouse A mouse is a pointing device that functions by detecting two- dimensional motion relative to its supporting surface. The mouses motion typically translates into the motion of a pointer on a display, which allows for fine control of a graphical user interface. A research has found that MOUSE is an acronym for (Manually Operated User Selection Equipment).
Inventor of the MouseDouglas Engelbart of the Stanford Research Instituteinvented the wheel-based mouse in 1963. The first ball-based mouse was invented by Bill English at Xerox PARC in1972.
Inventor of the Mouse…However, mice broke onto the public stage only in1984, with the introduction of the Apple Macintosh.
Mouse Actions Point Click Double Click Right Click Scroll Drag Drop Highlight
Basic Functions There are lots of different styles of mouse, but most have a left and a right button. Wheel/Scroller Left Mouse Button Right Mouse Button
Point means you move the mouse across a flat surface until the mouse pointer restson the item of choice on the desktop. It will appear as an arrow (pointer) for you to use to point.
Click Click means you press and release the primary (left) mouse button. You must point to an item beforeyou click. Be careful not to move the mouse while you are clicking.
Right-click Right-click means you press and release the secondary (right) mouse button. You will point to an object on the screen prior to right- clicking. Whenever you right-click an object, a context- sensitive, or basically a shortcut, menu will display. The use of shortcut menus speeds up your work and adds flexibility to your interface with the computer.
Double click You double click with the left mouse button to open things, such as a folder. Youneed to double click quickly, think about the knock, knock you do on a door.
Drag and drop Drag and drop is when you move something from one place to another. First select the item with the left mouse button and keep the button pressed down. Then move will move with the cursor. the mouse and the item on screen When you have the cursor and item in the position you want, release the left mouse button. The item will now be dropped into where the cursor is positioned on the screen. You use drag and drop to move things around your computer, such as files between folders.
Scrolling Wheel TheScrolling Wheel allows you to quickly scroll vertically on your page. Every mouse does not have a scrolling wheel, however, it is an efficient and convenient way to scroll up and down
How Data SentWhenever the mouse moves or the user clicks a button, the mouse sends 3 bytes of data to the computer. The first bytes 8 bits contain 1. Left button state (0 = off, 1 = on) 2. Right button state (0 = off, 1 = on) 3. Middle button state (0 = off, 1 = on) 4. 1 5. X direction (positive or negative) 6. Y direction 7. X overflow (the mouse moved more than 255 pulses in 1/40th of a second) 8. Y overflow
How Data Sent contd. The next 2 bytes contain the X and Y movement values, respectively. These 2 bytes contain the number of pulses that have been detected in the X and Y direction since the last packet was sent.
How Should I Hold the Mouse? Keep your arm straight without moving your wrist. Only move your arm and elbow, not your wrist. This will help to prevent carpal tunnel.
How Should I Hold the Mouse? Cradle the mouse by allowing your thumb to rest on the side while your pinkie and ring finger rest on the other side. Place your index finger on the left button and your middle finger on the right button
Why Does the Pointer Change Its Shape? TheI-beam appears when you are in any area that permits typing new text or editing existing text. It is also called the typing cursor. The cross-hair appears when you have the ability to change or move a window or graphic.
Why Does the Pointer Change Its Shape? Thedouble arrow indicates you have the ability to resize a window or graphic. Thedouble arrow indicates you have the ability to resize a window or graphic.
Why Does the Pointer Change Its Shape? When you see an hourglass, your computer is performing an action. Pleasebe patient and wait until the hourglass disappears

Mouse Types by Technology Used Early Mouse (First Mouse) • From left to right: Opposing track wheels by Engelbart
Mouse Types by Technology Used Mechanical Mouse Operating a mechanical mouse. • moving the mouse turns the ball. • X and Y rollers grip the ball and transfer movement. • Optical encoding disks include light holes. • Infrared LEDs shine through the disks. • Sensors gather light pulses to convert to X and Y velocities.
Mouse Types by Technology Used Optical Mouse • An optical mouse uses a light-emitting diode and photodiodes to detect movement relative to the underlying surface, rather than moving some of its parts as in a mechanical mouse.
Mouse Types by Technology Used Laser Mouse • This mouse uses a small infrared laser instead of an LED, which increases the resolution of the image taken by the mouse. This leads to around 20× more surface tracking power to the surface features used for navigation compared to conventional optical mice, via interference effects
Mouse Types by Technology Used Inertial Mouse • Inertial mice use a tuning fork or other accelerometer to detect movement for every axis supported. Usually cordless, they often have a switch to deactivate the movement circuitry between use, allowing the user freedom of movement without affecting the pointer position.
Left hand ? March 9, 2006 Roughly 13% of the population is left- handed, meaning there are around 850 million people on planet earth with a preference for using their left hand for a variety of tasks Earlierleft-handed computer users have only had the choice of navigating with an ambidextrous-shaped mouse or unnaturally using their right hand to scroll, point and click.
First Left Hand Mouse Logitechannounced its MX610 left-hand Laser Cordless Mouse in 2006
First Game Mouse The Razer DeathAdder Left-Hand Edition
Todaythere are many brand of left hand mouse devices available on the market. But you don’t always have to go and buy a left hand mouse. You can easily switch your ordinary mouse to left-handed mode.
How to reprogram themouse for left hand users?
Step 1 - Type “mouse” on your Start Menuand select the first entry.
Steps 2 - From the “Mouse Properties” selectthe “Button” tab
Now your primary selectbutton is your rightbutton, and the secondarybutton is the left button.
How to change mousepointers for left handusers?
Even though functionality of the button has changed, it can still be awkward to select items on screen with your left hand using the default cursors (because it is pointing to the north-west)
MSDNhas a free set of cursors designed for left- handed users, that can fix this problem for you.

After successfully implementing the left hand mouse pointers it will look like this (mouse pointer turning to the north east side).
The B.X. (Before Xerox) Era The mouse was invented by Douglas Engelbart in 1964. It consisted of a wooden shell, circuit board and two metal wheels that came into contact with the surface it was being used on. The rotation of each single wheel translating into motion along one of the respective axes. The name “mouse” originates from the fact that the device had a “tail” behind it, connecting it to a computer and a display and was the idea of Bill English, a colleague of Engelbarts and the person who actually built the prototype device.
The “ball mouse” and Xerox In 1972 Bill English and Jack Hawley for Xerox, refined the design of Engelhards mouse and added some interesting new features. replacement of the two gear-system with a small metal ball, pressed against metallic rollers for tracking the movement. improvement of the interaction system with the computer, which now does not require anymore an analog-to- digital converter, instead sending digital positional information directly to the computer.
Apple gets into the mouse game Around the same period, Steve Jobs was also looking for an innovative, inexpensive, mass-producible and reliable input system for his forthcoming Apple systems. As a result in 1983 Apples Lisa system made its way to the market. Its key components included the optical encoder wheels, a free-moving tracking ball, and a precision injection-molded inner frame. It also used a squeeze- release DE-9 connector and only one button, which remained one of the most famous trademarks of Apple mice for years to come.
Apple gets into the mouse game At the same period of time Another important research center involved in the development of mouse technology, apart from Xeroxs facility, was the Ecole polytechnique federale de Lausanne (EPFL) has introduced further developed mouse featuring a single hard rubber mouseball and three buttons, which, as we all know only too well, remained the mainstream solution until way into the 1990s
Experimenting with the first optical mouseand the first cordless mouse In 1981, Richard Lyon invented the first optical mouse at Xerox PARC. In1982, Steve Kirsch developed an optical mouse that required a mouse-pad with a grid printed on it for tracking. In1984, Logitech in Switzerland(one of the major players in market) introduced the worlds first cordless mouse.
The second half of the 1980s and early 1990s introduction by IBM of the PS/2 operating system and the corresponding mouse interface. ThePS/2 was the standard mouse connectivity interface for a very, very long time, only the advent of USB and of the various wireless connectivity solutions making it slowly disappear
The second half of the 1980s and early 1990s Towards the beginning of the 1990s, Logitech managed to refine its cordless mouse design and came up with RF-based solutions, the first of which was called the Cordless Mouse- Man and arrived on the market in 1991. Still too expensive for most people to afford, but at least it was a step in the right direction. In 1993, Honeywell launched an alternate approach to the mouse tracking concept, namely the Opto- Mechanical mouse, which used two small angled discs on its bottom that track movement instead of the ball.
Lets start scrolling! The first mouse equipped with a scroll wheel was the ProAgio, developed by Mouse Systems back in 1995. Unfortunately, this model went fairly unnoticed, but we cant say the same about Microsofts scroll- wheel equipped peripheral, which arrived on the market a year later, in 1996.
Going for USB Back in 1998, Apple was one of the first companies to use USB for its mice. After that, a lot of companies adopted the USB interface and, nowadays, there are very few mice featuring PS/2 connectors out of the box (if any).
The Optical Mice Optical mice appeared towards the end of the 1990s, in 1999, to be precise, following a development by Agilent Technologies, which created the first optical mouse sensor that works without need for a special pad. The solution was quickly adopted by almost all peripheral manufacturers, including Microsoft, Apple, Logitech, etc.
Going wireless The two main competitors in this field are RF (radio) and Bluetooth technologies, most manufacturers going for either of the two or both solutions.
Laser Mouse The first working models were delivered by Sun Microsystems in 1998. In 2004, Logitechs MX1000 mouse hit the shelves, bringing laser into the mainstream. Laser technology provides seriously improved tracking resolutions by replacing the LED light with a laser engine. Providing more accurate tracking than optical mice, laser-based peripherals are also a bit more expensive, and for this reason, theyre mostly targeting the gaming segment, where speed and accuracy are extremely important.
Microsofts BlueTrack enters the mouse game In 2008, Microsofts hardware- oriented division came up with yet another innovation in the field of computer peripherals and tracking technology, namely BlueTrack. Thiscomplex solution uses elements from both laser and optical technologies, allowing mice to be used on pretty much any type of surface, as long as its plane, of course.
Apple Magic Mouse Apple released the Magic Mouse in 2009, with a minimalist design and a multi-touch pad covering the whole surface of the mouse.
Future of the mouse There are lots of new experiments going on the field of interaction between humans and computer today. People are researching on innovative, more accurate and more faster ways of communicating with devices. Hand aided mouse is becoming an old slow technology. So in near future it will be an obsolete technology which beautifies the history of evolution in the interaction devices.
Future of the mouse contd.. Multi touch enabled devices. • Uses simple finger gesture for issuing complex commands. • It is more than what we do with mouse. (E.g.:- Double clicking, pointing to an icon in the desktop.) • E.g.:- “pinching” – using two fingers to zoom in and out a picture or the screen. • Apples new Magic Mouse is actually a gesture-recognizing touch pad.
Future and new trends contd.. Gesture sensing. • Its more than what we do with motion of the boll in a mouse to track the movement and move the curser accordingly. • Gesture sensing allows the user to give a command in a three dimensional space. • In the games players can shoot using finger gestures and captures the physical movements of the humans to play the games and other movements. • This can interact with more real time sense of doing something for a rich human computer interaction. • By taking human-computer interactions outside of the two- dimensional screen of the computer, it makes the time we spend with our computers will become more physical, rewarding and effective.
Future of the mouse contd.. Brain Computer Interfaces. • We need to think what we want to do and computer will do it for us.
Future and new trends contd.. So people are moving to use the brain signals or waves to capture and use it in the computer functionality. This is more and more faster that we can’t even imagine. With those technologies mouse is definitely going to be dead in future.
Future and new trends contd.. Voice recognition and Eye tracking Instead of bothering to handle a mouse and pointing it on the screen users can just speak to the computer and get things done. Helps to use in people who have disabilities in using physical devices. This interaction interface is much flexible with every one.
Future of the mouse contd.. It needs to have a look and the eye movements will be captured as an input to the system. So-called eye tracking relies on a high- resolution camera and an invisible infrared light source to detect where a user is looking.
