Douglas Engelbart was (mouse) computer how! Douglas Engelbart was invented in 1964, it is not anything new or too invented in 1964, it is not anything new or too much trouble, but is an indispensable component much trouble, but is an indispensable component in the past few decades. In many years of in the past few decades. In many years of development, computer mouse also has many development, computer mouse also has many changes and improvements, not only in design but changes and improvements, not only in design but also sensor technologies. Mouse sensitivity and also sensor technologies. Mouse sensitivity and now features much better than a few years ago. now features much better than a few years ago. 4 5 2 2 . Touch Mechanism: . Touch Mechanism: a. Mechanics: a. Mechanics: This is the beginning of the mouse mechanism and This is the beginning of the mouse mechanism and extends dozens of years later and still can find all extends dozens of years later and still can find all kinds of mouse balls (a branch of the mechanism kinds of mouse balls (a branch of the mechanism of induction) in the shop. Computer mouse first of induction) in the shop. Computer mouse first appeared in the world of good size with two appeared in the world of good size with two wheels perpendicular to each other and you will be wheels perpendicular to each other and you will be using both hands to control it: a hand holding a using both hands to control it: a hand holding a mouse and holding a small keyboard mouse and holding a small keyboard approximately 5 buttons. By 1970, engineers at approximately 5 buttons. By 1970, engineers at Xerox PARC Bill Tiếng Việt wheel was replaced Xerox PARC Bill Tiếng Việt wheel was replaced with a classic ball-known that we all know. with a classic ball-known that we all know. 6 This marbles can move in any direction, this This marbles can move in any direction, this motion will be two small wheels inside the motion will be two small wheels inside the mouse recognized, the wheel has small slits mouse recognized, the wheel has small slits allow a flash of light to the touch through the allow a flash of light to the touch through the other side, each interrupt will indicate the mouse other side, each interrupt will indicate the mouse is moved. Finally, a sensor signal will collect and is moved. Finally, a sensor signal will collect and review the value of the corresponding review the value of the corresponding coordinates of the mouse on the screen. This coordinates of the mouse on the screen. This design is used throughout the 80s, 90. modern design is used throughout the 80s, 90. modern design that you see the original design at the design that you see the original design at the academy EPFL (the heart of European academy EPFL (the heart of European technology that period), then the finished technology that period), then the finished product is marketed through a first branch of the product is marketed through a first branch of the EPFL which later became one of the pointing EPFL which later became one of the pointing device manufacturer (Pointing Device) names - device manufacturer (Pointing Device) names - Logitech Logitech 7 b b . Optical: . Optical: The mechanism of optical mice is remarkable The mechanism of optical mice is remarkable progress in fabrication of the mouse. It removes progress in fabrication of the mouse. It removes all mechanical components (bearings and all mechanical components (bearings and wheels), replaced by a micro-capture device. This wheels), replaced by a micro-capture device. This device will continuously capture the surface that device will continuously capture the surface that the user moves the mouse and through the the user moves the mouse and through the comparison between these photos, the processor comparison between these photos, the processor inside the mouse coordinates will be calculated. inside the mouse coordinates will be calculated. Roughly speaking, the mouse ball using optical Roughly speaking, the mouse ball using optical sensors to capture the motion of the ball, then sensors to capture the motion of the ball, then use the mouse optical recording device to use the mouse optical recording device to capture the motion of the surface. capture the motion of the surface. 8 In fact, to calculate exactly the right shots well. In fact, to calculate exactly the right shots well. So the first important task is to have the device So the first important task is to have the device illuminates the surface and a device called a red illuminates the surface and a device called a red LED is used for this. When illuminated surface, LED is used for this. When illuminated surface, light rays will be reflected and focused through a light rays will be reflected and focused through a lens before touching the sensor. Thus the image lens before touching the sensor. Thus the image will be very detailed. The advantage of next will be very detailed. The advantage of next generation optical mice are not organs should be generation optical mice are not organs should be absolutely no fear of failure due to corrosion or absolutely no fear of failure due to corrosion or dirt. The maintenance is very simple (just wipe dirt. The maintenance is very simple (just wipe the eye to read is finished). Addition of detail the eye to read is finished). Addition of detail and sensitivity of optical sensor mechanism is a and sensitivity of optical sensor mechanism is a lot better. lot better. 9 However, no optical mouse can work on However, no optical mouse can work on transparent or glossy surface, and the showy transparent or glossy surface, and the showy surface, the mouse does not operate correctly. This surface, the mouse does not operate correctly. This is true with the first generation rats. In addition, is true with the first generation rats. In addition, some mice are inexpensive image processing some mice are inexpensive image processing system less will not be able to calculate when the system less will not be able to calculate when the user moves with high speed (high mouse speed can user moves with high speed (high mouse speed can be moved by up to 1 m / s .) and weaknesses of be moved by up to 1 m / s .) and weaknesses of the optical mouse is the ultimate crash more the optical mouse is the ultimate crash more electricity than mechanical mice. electricity than mechanical mice. 10 c c . Laser: . Laser: Laser sensor technology is the latest and most advanced today. Not only inherits all the advantages of optical laser mouse that has many characteristics of other Vietnamese priority. First introduced in 2004 under the cooperation of Logitech and Agilent Technologies, Logitech MX1000 is the first representative of the generation laser mouse appeared on the market. This mouse uses a small laser replacement for small conventional LEDs. Laser technology allows light rays have a higher concentration and stability in particular. [...]... data channel increased accuracy and decreased latency compared with 8-bit connection commonly found on the mouse "ordinary." 14 b Wireless: Radio: this is the type of wireless connection first and most common is the manufacturer of equipment for their wireless mouse A computer mouse using this type of communication signal receiver connected to a computer and a wireless mouse battery left These two components... features of it (later versions do not fall into that) 11 12 3 CONNECTOR STYLE: a Wired: Serial: serial mouse uses a serial port (also called a COM port) are very common in 90th decade but is now very rare, partly because the COM port and slow aging gradually eliminated from the next generation computer new In addition, the dominance of USB also contributed "off" it is history PS2: used in a long time and... technologies such as Logitech's Fast RF significantly reduced the lag when playing, receiving signals 15 Bluetooth: capital is seen as a type of wireless connection to exchange data between mobile devices Recently, the pointing device using a Bluetooth connection to appear more on the market Some such as the Logitech diNovo Media Desktop or Microsoft Optical Desktop Elite for Bluetooth Basically, using... recorded via the electromagnetic field between the touchpad connected to the computer and mouse However you should note that RFID is limited in range of operations: just the right length of wire where you go into a computer USB port 17 c Apple Desktop Bus Born in 1986, this is a technology invented by Apple Desktop Bus for Mac.Apple machine capable of connecting directly to 16 devices and used in most Mac... accuracy again increases proportional to the speed of the mouse 22 So you can move the cursor to the point I want very quickly, without having to scroll a lot but on the contrary, any move that even the smallest will be recorded and this is not conducive to the main determined Complicating the user when the mouse's DPI index depends on the screen resolution you use For example: with the same level of DPI,... particular goal For example, when your hand or shoulder pain while using the conventional mouse, you can try this product just because Trackball requires users to move a finger to move the cursor Currently, you can see the kind of mouse "hybrid" as follows: 27 - Trackball instead of the mouse to move the ball with Trackball, users will control the cursor on the screen through a large ball placed on a fixed... the more the image is "captured" from the sensor of the mouse, its accuracy will be higher Some suggest that the power of current computer processor at the same time only a few hundred patterns per second This is true but if more and more number of samples, the average value and will become more standard practice, the intermediate device shall calculate the coordinates of the processor inside the mouse... by Apple Desktop Bus for Mac.Apple machine capable of connecting directly to 16 devices and used in most Mac products Model up to 1998 when the iMac was The first switch using USB In early 2005, this connection type again be used in the PowerBook G4 computer systems in the role of communication between computer and keyboard with integrated trackpad of it 18 4 The Keys and scroll wheel: According to... 2000dpi is actually capable of meeting the speed of the mouse with the player's reaction even at high resolution From there, we found that, due to the precision proportional to movement speed, so the control will be more difficult Manufacturers have many ways to handle this problem through software or hardware directly 24 However, the main principle is to ignore the pixels and thus clear the precision... called "tilt wheel" (tilt-wheel) for their high quality products 19 With the new wheel, users can ricochet two sides to implement horizontal scroll function Sometimes you can also find products that use continuous sensor technology instead of wheels and easy to dust problems, for example, the Logitech V500 20 5.Speed and accuracy Commercialization and marketing has made the way the specs of the mice became
