- 4. What is Mouse ? ? A computer mouse is a hand-held pointing device that detects two- dimentional motion relative to a surface. ? This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface. Why it is named as ¡°Mouse¡± ? ? With the cord coming out of the back of the mouse Douglas said the device reminded him of the rodent mouse and the name stuck. ? It's a lot easier to remember than a ¡±X-Y Position Indicator for a Display System¡±.
- 5. Invention of Mouse ? In 1968, a man named Douglas Engelbart created this special tool to help people control their computers. ? It was a small wooden block on wheels, and there was a long cable sticking out of the back, kind of like a tail!
- 6. Activities of Mouse ? Move the mouse cursor ? Open or execute a program ? Select ? Drag-and-drop ? Hover ? Scroll ? Perform other functions
- 7. Types of Mice / Mouses ? Cordless (Wireless) ? Footmouse ? IntelliMouse (Wheel mouse) ? J-Tech Mouse ? Joystick ? Optical Mouse ? Gest ? gStick Mouse ? Touchpad (Glidepoint) ? Mechanical ? Trackball ? TrackPoint
- 8. How Mouse Works (Mechanical Mouse) ? When the mouse moved, this movement rolls a ball found inside. ? The mouse should place on flat table or mouse pad in order to move. ? The two axles (represent the X and Y direction) will turn as a result of the rolling ball. ? Each axle connects to wheel (resembles like a gear) which spins when the axle rotates.
- 9. ? Beside each rotating wheel, there are an infrared LED (light- emitting diode) and infrared Sensor. ? The LED sends a path of light to the wheel. ? The sensor, found on the other side of the wheel, detects the pulses of light interrupted by rotating wheel. ? The mouse on-board processor chip reads the pulses from the sensor and translates into computer usable format (binary data). ? This tells the mouse position and speed which is displayed in the movement of a cursor on a screen. How Mouse Works (Mechanical Mouse)
- 10. How Mouse Works (Optical Mouse) ? Today, ball mouse is replaced by optical types which use LED and a small camera to sense the movement of a mouse. ? Optical mouse actually uses a tiny camera to take 2000 pictures every second. ? The mouse has a small, red light-emitting diode (LED) that bounces light off that surface onto a complementary metal-oxide semiconductor (CMOS) sensor. ? The CMOS sensor sends each image to a digital signal processor (DSP) for analysis.
- 11. How Mouse Works (Optical Mouse) ? The DSP, operating at 18 MIPS (million instructions per second), is able to detect patterns in the images and see how those patterns have moved since the previous image. ? the DSP determines how far the mouse has moved and sends the corresponding coordinates to the computer. ? The computer moves the cursor on the screen based on the coordinates received from the mouse. ? This happens hundreds of times each second, making the cursor appear to move very smoothly.
- 12. Most modern Mouse has the following parts ? Case ? On-board processor chip ? Two buttons ? A wheel between the two buttons (used to scroll up and down, Zoom IN and Zoom Out in applications like AutoCAD) ? Battery (if it is wireless) ? Connection interface such as USB or Infrared
- 13. Computer mouse ports ? Bluetooth ? PS/2 Port ? Serial Port ? USB ? Infrared Today, most computer mice connect to a computer using a USB port. Below is a listing of all the type of ports and wireless connections that a mouse is capable of using or has used in the past.
- 14. How has the Design being changed ? The computer mouse has definitely changed size, getting smaller and smaller. ? The design has also become more comfortable to hold, as the first computer mouse was quite square. ? Motion detectors have changed from a tracking ball, to an LED light, and now a laser.
- 15. How has the Design being changed ? This improves the quality of motion we see on the screen, and also eliminated the use of the mouse pads. ? A ¡®scroll wheel¡¯ is also available on most mouses, making it easier to view web pages and folders.
