8. Chapter 1. History & Developing

10. December 9, 1968, the world's first mouse was born in California, Stanford University, its inventor Dr. Douglas Englebart. original intention was to make the operation of the computer easier to replace the cumbersome command of the keyboard. Who Invention ?

11. With the augment computer use, the first mouse device looks very simple, it is an analog device, relying on the bottom two metal wheels, drive axle is connected to the variable resistor to generate mouse displacement signal. The first prototype of a computer mouse

12. How is work ?

13. Analog signalsContinuously varying electromagnetic wave transmitted through a variety of transmission media. Digital signalThe continuous voltage pulse is mainly based on the type of potential state. Digital and analog systems comparison:Digital system operator is accurate, it is not easy to noise interferenceSignal storage, easy to edit. But it is a distortion of the wave.

14. Serial port (RS-232): Mainly used for serial bit-by-bit data transfer.General computer applications RS-232 (25-pin or 9-pin connector) and industrial computer applications half-duplex RS-485 with full-duplex RS-422.

15. Abbreviation Pin meaning Explanation Tell the computer modem carrier is detected. Receive data. Transfer the data. The computer tells the modem can be transmitted. Ground. Modem tells the computer everything was ready. Computer modem to send data. Tell the computer modem can transfer data . Tell the computer modem signal comes.

16. Serial Port Specifications:Serial port points, According to electricity standards and protocols including: RS-422 RS-232-C RS485 USB PS/2

17. 1972~1983Location &input have began to change

18. in 1972 replace the metal wheel to wheel mouse by Xerox Corporation, scroll not only the X and Y-axis mode. In early 1980, by Steve Kirsch designed one of the most original version of the optical mouse.

19. Grating

20. In 1983, Logitech invented the first optical-mechanical mouse P4, which is what we today call the mechanical mouse. This mouse structure has become a de facto industry standard. The initial listing price of $ 299!!

21. Operating an opto-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 vectors. opto-mechanical mouse.

22. In 1983, Microsoft launched its own mouse, affected the entire computer industry in the next 20 years, when the mouse asking price is $ 195 USD Apple also introduced a desktop computer with a mouse, an asking price of $ 9,995 USD

23. Naming of PS / 2 from 1987 when IBM introduced the PC: PS / 2 series. PS / 2 mouse connection is usually used to replace the old serial mouse interface (DB-9 RS-232) The color-coded PS/2 connection ports (purple for keyboards and green for mice) PS/2

24. Specifications:Pin number (from the slot into) • * On some notebook mouse data for splitter cable.** On some notebook mouse clock for splitter cable.

25. 1989 ~2000Operation & Transmission Technical Great Leap

26. 1989, trackball technology, first applied to the mouse By Canada's Royal Navy in 1952 designed the first trackball TrackMan Because the trackball mouse strong positioning capability and accuracy at the same time caused a great sensation in the professional field and boom.

27. Advantages : Disadvantage : Trackball By reading the direction and speed of the scroll ball scrolling to locate.

28. In 1991 the first wireless mouse by Logitech Logitech invention, the first 27 MHz RF wireless technology. 1995 by Eric Michelman the wheel in the middle of the left and right keys.

29. Include 27Mhz, 2.4G, Bluetooth, Wi-Fi (IEEE 802.11), Infrared (IrDA), ZigBee (IEEE 802.15.4). 27Mhz Radio Frequence? 27 MHz ISM (Industrial, Scientific, Medical) radio frequency . In this frequency band four channels around the world: two for the wireless keyboard, the other two for the wireless mouse; 27Mhz farthest effective transmission distance of only 6 feet (182.88cm) Wireless Mouse Mega Hertz, (MHz)Fluctuation frequency of one of the units. 1 Hz = 1/s

30. Universal Serial Bus ,abbreviation of “USB” A serial port bus standard is the the connection computer system with an external device USB 1994，Compaq, DEC, IBM, Intel, Microsoft, NEC and Nortel

32. In 1996, Microsoft released a standard mouse has a rubber plastic roller wheel. The Apple ‘hockey puck’ mouse appears in 1998 and it’s is notable as the first Apple mouse to support the USB peripheral standard .

33. 2000~nowHigh-tech era

34. In 2000, Apple releases the first mouse with an optical tracking sensor. In 2002, Logitech introduced the first Bluetooth mouse.

35. The human eye to light in the visible wavelength range of about 400 ~ 700nm, this range of wavelength is referred to as the infrared ray is less than compared to UV light. There will be a prism of the light output of the light turning Light-Emitting Diode (LED) by infrared

36. Through the barriers to the ability to use infrared LED Long-wavelength light penetrating and will be better directivity.

37. Bluetooth uses frequency bands and 2.4G RF are free in most countries, authorized 2.4-2.485GHz ISM "Bluetooth" technology was developed by a company established in September 1998, the private, non-profit organization Special Interest Group (SIG) to develop a standard. Bluetooth Version 1.0、1.1、1.2、2.0、2.1、4.0

38. 2004, the first mouse to use a laser for optical tracking, the MX 1000. The laser tracking system. 2005 launched the first dedicated to people with disabilities to use the foot mouse

39. The spent two mutually parallel optically reflective surface forming of Seismic chamber, to form a total internal reflection and generating a narrow beam. Laser engine

40. In 2006, the advent of Bluetooth Laser Mouse 2006, Logitech LogitechMX Air power shot Super Mouse

41. Phone and mouse combo mouse phone was launched by SONY In 2008, Microsoft introduced the Blu-ray Mouse with Blue Track technology, compatible with all interfaces (Microsoft SideWinder X8).

42. Blue LED (wavelength of about 450 nm) and a high degree of scattering, four times more than the average optical irradiation area light dispersion mirrors, increased resolving power characteristics. Through the media capacity is very low, the glass can also be used Blue ray - LED

43. In 2008, Logitech ships its one-billionth mouse since it began selling them in 1982. In 2011, Cybork release the top of mouses, the R.A.T.9 Gaming Mouse.  Nothing can beat this piece of art !

44. In 2009, Logitech launch DarkField laser tracking technology can also be used in the glass . Usually only use a set of positioning problem in a transparent material, it will enable the second group

45. In 2009, Apple introduced new Mouse Magic Mouse with multi-touch technology.

47. CPI（Counts Per Inch） DPI（Dots Per Inch） CPI & DPI 1920×1080 960 DPI Sensei MLG 16400 DPI!! 1920 DPI

49. The location of the sensor will greatly affect the operation flu.

50. Frame Per Second (FPS) : It represents the sampling frequency of the induction engine per second. Laser Gaming Mouse up to 12000FPSOptical Gaming Mouse only 6400FPS ~ 9000FPSGeneral optical mouse has only 3000FPS frame rate is higher than about 10-12 frames per second, this phenomenon is called persistence of vision. Early optical engine, FPS value is only 1500,and now up to 6000FPS.
