Koj puas paub tias nas kho qhov muag yog dab tsi? Khoos phis tawm nas yog ib qho khoom siv tes tuav taw tes rau cov khoos phis tawj, suav nrog ib qho khoom me me uas tau txav mus nyob rau hauv phau ntawv tswj tsis pub dhau ob qhov ntev raws ib qho chaw. Hauv cov ntsiab lus hauv computer, nas yog tus kheej lub computer peripheral uas yog siv los tswj kev txav ntawm tus cursor ntawm lub computer screen. Cov ntawv tshaj tawm blog no saib keeb kwm ntawm nas thiab nws qhov tseem ceeb hauv lub ntiaj teb computer.
Keeb kwm ntawm nas:
Computer nas tau los ntev hauv ob peb xyoo dhau los. Thawj nas, invented hauv 1963 los ntawm Douglas Engelbart, yog cov khoom siv hlau thiab ntoo nrog ob lub log thiab khawm. Nws yog raws li thaum ntxov teleprinters uas tau siv nrog thawj computers. Txhawm rau siv nas, tus neeg siv yuav txav ib qho ntawm cov log nyob rau hauv qhov kev taw qhia rov qab ntawm qhov chaw uas lawv xav kom tus cursor txav mus.
A nas xav tau vim tias teleprinters muaj cov keyboard thiab lub tshuab luam ntawv tab sis tsis muaj txoj hauv kev los txav tus cursor ntawm lub vijtsam. Engelbart tus nas tau txhim kho los ntawm Bill English ntawm Xerox Palo Alto Research Center (PARC) thaum ntxov xyoo 1970. Nws yog tom qab ntawd tus nas tau txais nws lub npe. Tus nas Xerox tau txuas nrog lub khoos phis tawm los ntawm txoj hlua. Nws muaj peb lub khawm thiab lub log scroll. In addition, tus nas tsis txuas nrog lub khoos phis tawm los ntawm txoj hlua khi — nws yog wireless.
Dab tsi yog Optical Mouse?
Ib qho nas kho qhov muag yog lub computer nas uas siv LEDs lossis laser los taug qab lossis ntes kev txav mus los. Nws yog thawj zaug qhia los ntawm Microsoft thaum lub Plaub Hlis 19, 1999. Nws yog thawj tus nas uas tau tsim los ntawm kev siv kho qhov muag thev naus laus zis. Tus nas kho qhov muag muaj peev xwm daws teeb meem ntau dua.
Tus nas kho qhov muag yog cov cuab yeej nkag siab uas ntsuas nws qhov kev txav los ntawm kev teeb pom kev zoo ntawm qhov chaw hauv qab nws nrog lub teeb tsis tshua muaj zog, tom qab ntawd taug qab lub teeb thaum nws cuam tshuam rov qab siv lub sensor. Tus nas kho qhov muag yog cov cuab yeej nkag siab uas ntsuas nws qhov kev txav los ntawm kev teeb pom kev zoo ntawm qhov chaw hauv qab nws nrog lub teeb tsis tshua muaj zog, tom qab ntawd taug qab lub teeb thaum nws cuam tshuam rov qab siv lub sensor.
Tus nas kho qhov muag tuaj yeem ua haujlwm ntawm txhua qhov chaw, thiab nws tsis xav tau ib qho nas ncoo. Lub laser yog nyob rau hauv qab ntawm tus nas thiab yog siv los taug qab kev txav mus los. Nws zoo ib yam li nas pob tab sis ua haujlwm nrog lub tshuab kho qhov muag. Muaj ob qho ntawm cov nas kho qhov muag, ib qho uas siv LEDs thiab ib qho uas siv laser.
Lawv feem ntau siv rau hauv desktop computers tab sis tuaj yeem nrhiav tau nrog laptop computers. Cov nas kho qhov muag feem ntau nyiam dua li cov nas pob vim tias lawv tsis xav tau qhov chaw nrog ib qho nas ncoo lossis nas nto, lossis tus neeg siv rau “cheb” the mouse back and forth over the pad or surface.
Optical mice have been the standard for quite some time and are still the most popular choice. They operate by tracking the movement of light over the surface of the mouse. tiam sis, there are some drawbacks to using an optical mouse. There are many criticisms pointing to their sensitivity and poor accuracy. They are also not as durable as their counterpart, the mechanical mouse.
Optical mice were introduced as an alternative to mechanical mice. They work by clicking buttons, which send signals and data to the computer. Optical mice have a much longer life span than mechanical mice because they do not contain any moving parts.
LED nas
An LED mouse uses a red (or blue) lub teeb-emitting diode (LED) txhawm rau teeb pom kev zoo rau saum npoo hauv qab nws thiab siv lub photosensor los kuaj pom cov kev hloov pauv ntawm tus qauv ntawm lub teeb. Tus nas taw qhia ntawm nws tus nas LED tau daig thaum nws tau muab tso rau ntawm cov ntaub pua plag tuab lossis daim pam, thiab nws yog qhov nyuaj rau txav tus nas pointer thaum lub sijhawm ntawd. Tus nas LED yog qhov zoo tshaj plaws vim tias nws ua haujlwm zoo tshaj plaws ntawm qhov chaw mos.
Cov nas kho qhov muag siv LED thiab lub teeb sensor los kuaj pom kev txav mus los. Lub LED tso tawm lub teeb ntawm lub teeb. Raws li tus nas txav mus, lub teeb cuam tshuam tawm ntawm qhov chaw hloov. Lub teeb sensor pom lub zog ntawm lub teeb cuam tshuam los ntawm qhov chaw. Cov nas tom qab ntawd xa cov ntaub ntawv mus rau lub khoos phis tawm. Lub khoos phis tawm txheej txheem cov ntaub ntawv thiab hloov nws mus rau hauv nas txav uas tso cai rau koj siv tus nas tib yam li koj yuav nrog ib tug neeg kho tshuab nas. In addition to being more reliable and accurate than mechanical mice, optical mice also use less battery power and have a longer lifespan.
Laser nas:
A laser mouse is a computer mouse that uses a laser beam to detect movement relative to the mouse’s surface. The first optical mouse was invented in 1996 by Kenjiro Takayanagi at the Japanese company Logitech. The laser mouse was presented in the late 1990s, and it superseded the old-style mechanical mouse because its sealed bottom surface did not absorb dust and dirt.
The laser mouse uses a laser diode to project a light spot onto the surface. The light spot is translated into the movement of the cursor on the screen. The laser mouse is more expensive than the LED mouse and requires a special nas ncoo. The laser mouse, on the other hand, works best on hard surfaces because it emits a beam of light and detects the movement of the beam of light. If the mouse is a laser mouse, you should check how many DPI it has and whether or not it is adjustable. If you are going to buy a mouse that is comfortable to use, you should buy one that is not too light or too heavy.
Optical mouse vs Mechanical Mouse
Optical mice use an LED light source and a photosensor to detect movement. The LED illuminates the surface under the mouse, and the photosensor picks up the reflected light. The sensor reports changes in the light’s intensity to the computer, which processes the movement data and translates it into cursor movement.
Mechanical mice still use a rubber ball. The ball is mounted on a shaft, and it rolls around inside the mouse as you move it. The mouse’s circuitry detects the position of the ball by counting the electrical pulses generated by the ball’s movement. This information is then sent to the computer, where the cursor is moved.

Hope you enjoyed our article about what is optical mouse. The optical mouse is a very useful tool and can be used by anyone. Nrog rau qhov kev paub no, you can be able to use your mouse more accurately, with more control, and in a way that is more comfortable for your hand.
At this point, you should have a good idea of what an optical mouse is and whether or not you would prefer it over a regular nas. If you’re still not sure, you can always try one out for yourself and make the decision based on your personal use. As we briefly touched on above, there are many different types of optical mice available. This can make the buying process a bit more difficult. Uas tau hais tias, if you keep a few things in mind, it should be relatively easy.
First and foremost, think about the size and shape of your hands. The larger the hands, the larger the mouse. There are also ergonomic mice that are specifically shaped to fit a certain hand size. For example, if you have small hands, you might want to consider a mouse that has an ergonomic shape that is designed to fit small hands. You should also think about the type of surface you’ll be using the mouse on. If you’ll be using your mouse on a regular basis.
