The mouse!

  1. 1. New Product Development
  2. 2. The Mouse !  In computing, a mouse is a pointing device that functions by detecting two- dimensional motion relative its supporting surface (a mouse pad)  The name mouse, originated at the Stanford Research Institute, it use to have a cord at the back of the device which resembled a mouse tail.
  3. 3. The invention of mouse Douglas Engelbart changed the way computers worked in 1964. He invented the computer mouse, a user friendly tool that anybody can use.
  4. 4. HOW IT CAME TO BE! The trackball, the first version of the mouse was invented by Tom Cranston, Fred Longstaff and Kenyon Taylor who were working on the Royal Canadian Navy‟s DATAR project in 1952. It used a standard Canadian five-pin bowling ball. It was a secret military project.
  5. 5. WHY DO WE NEED IT? The mouse allows the user to operate on a GUI (graphics user interface) which is usually displayed via a monitor. It is possible to use a computer without a mouse or a touchpad (“laptops mouse”) as you can navigate with just the keys but that may be a little tricky for the average person.
  6. 6. The First MouseThe first mouse was designed 1970 in the U.S. by Douglas Englebart and constructed by Bill English in 1972.
  7. 7. Mechanical Mouse:This type of mouse was the first one around which uses amoving ball inside to work. As you move the mouseacross a surface, the ball moves too. Two rollers are alsoinside the mouse which track the horizontal and verticalmovement of the ball.
  8. 8. Optical Mouse:The most common type of mouse in use today. Thismouse uses optical technology, so it doesn‟t requiremoving parts. The LED light inside the mouse, reads thepattern or grid on the surface.
  9. 9. Laser Mouse:This mouse works very similar to the opticalmouse, but produces better results. Laser micecan work flawlessly on any type of surface.
  10. 10. How has the design changed•The computer mouse has definitely changed size, getting smaller and smaller.•The design has also become more comfortable to hold, as the first computermouse was quite square.•Motion detectors have changed from a tracking ball, to an LED light, and now alaser. This improves the quality of motion you see on the screen, and alsoeliminated the use of mouse pads.•A „scroll wheel‟ is also available on most mouses, making it easier to view webpages and folders.
