Theinventionofthemouse
ThemousewasinventedbyDouglasEngelbartin1964,whenDouglasEngelbartworkedattheStanfordResearchInstitute(SRI),aninstitutionsponsoredbyStanfordUniversity,DouglasEngelbarthaslongbeenthinkingabouthowtomakecomputeroperationseasierandhowtoreplacethecumbersomeinstructionsenteredbythekeyboard.
Intheearly1960s,whenheattendedameeting,hetookoutanotebook(notalaptop)thathecarriedwithhim.Hedrewapictureofusingtwomutuallyperpendicularwheelsatthebottomtotrackthemovement.Thisistheprototypeofthemouse.In1964,DouglasEngelbartonceagainperfectedtheconceptofthisdeviceandproducedthefirstfinishedproduct.ThereforeDouglasEngelbartisalsoknownasthe"fatherofthemouse."
Atthattime,therewasno"mouse"name.Thisnewdevicewasasmallwoodenboxwithtwoscrollwheelsbutonlyonebutton.Itsworkingprincipleisthattherollerdrivestheshafttorotate,andtherheostatchangestheresistancevalue.Thechangeoftheresistancevalueproducesadisplacementsignal,andthecursorindicatingthepositiononthescreencanbemovedafterprocessingbythecomputer.
Тъй като устройството се влачи по жици като мишка (като опашка на мишка), Дъглас Енгелбар и колегите му го нарекоха на шега „мишка“ в лабораторията. Той също така смяташе, че мишката може да се използва широко в бъдеще, така че когато кандидатствах за патент, под името „индикатор на XY позиция на дисплейната система“, но хората усетиха това име“ Мишката"беше по-сърдечна,така беше"мишка".обаждане.
Afterthemousewasinvented,itwasfirstappliedtotheimprovedAltocomputersystembyXeroxin1973,butunfortunately,thesesystemswereallexperimentalandusedforresearchwork.Ithasnotbeenpromotedtothegeneralpublic,sothemousehasalwaysbeenunknown.
In1979,ApplefounderSteveJobswasinvitedtowatchAltoandthesoftwarerunningonthesystem.Jobswasshockedbythecomputertechnologyhesaw,andherealizedthatthesetechnologiesrepresentedthefuturedevelopmenttrendofcomputers.ThesetechnologiesincludetheuseofamouseasapointinginputdeviceandaGUI(GraphicsUserInterface)usedbytheoperatingsystem.Appleimmediatelyaddedthesefunctionstoitsownsystem,preparingtodevelopanewtypeofhomecomputer,andhiredadozenXeroxtechnicianswithhighsalaries.In1981,XeroxlaunchedtheStar8010computerthatusesamouseandaGUIoperatingsystem.Thisisthefirsttimethatthepublichaslearnedaboutamouse.Unfortunately,thepriceofthiscomputeristooexpensiveandthesalesvolumeissmall.Nevertheless,themousehasattractedtheattentionofmanypeopleandhasbeguntobemasteredbypeople.
In1983,AppleofficiallylaunchedtheLISAcomputer,whichwasApple’sfirstcomputerusingamouse.Itfurtherintroducedthemousetothemajorityofusersandmadethemrealizetheroleofthemouse.
In1984,LISA'supgradedproduct,theMacintosh,cameout.ThiswasamilestoneforAppleandalsoamilestoneinthehistoryofcomputerdevelopment.WhileitbroughthugeincometoApple,italsoallowedthemousetogo.Intothousandsofhouseholds.Later,duetothewidespreaduseofOS/2andWindowssystems,theapplicationofmouseandGUIwasfurtherpromoted,makingthemousegraduallypopular,andeventuallybecamethestandardconfigurationofcomputers.Sincethen,everycomputerhasaloyalcompanionnexttoit.,Thatis"Mouse"-mouse.

Ofcourse,fromtoday’spointofview,thisoriginalmouseisindeedquitecrude.Itusesanall-woodshell,whichhassharpedgesandcorners,islargeandheavy,andrequiresanadditionalpowersupplytoworkproperly.It'snotconvenient.Coupledwiththeuseofalargenumberofmechanicalcomponents,astimeaccumulates,themousewillhaveveryseriouswearproblems.Inaddition,theoriginalmouseusesanalogtechnology,anditsresponsesensitivityandpositioningaccuracyarenotideal.Allthedrawbacksaddup,resultinginnotmanypeoplewillingtouseit.Butasanascentnewproduct,wecan'tdemandtoomuchofit.Thegreatestsignificanceoftheoriginalmouseisthatitsbirthmeansthattherearemorechoicesofcomputerinputdevices,andlaidthefoundationfortheoperatingsystemtoadoptgraphicalinterfacetechnology.ItisdifficultforustoimaginehowusersshouldoperateWindowsifthereisonlyakeyboard.OrMacOS.

Класификация на типа
Според типа на интерфейса мишката може да бъде разделена на четири типа: серийна мишка, PS/2 мишка, шинна мишка и USB мишка (предимно оптична мишка). Тази серийна мишка е свързана към компютъра чрез сериен порт и има два типа: 9-пинов интерфейс и 25-пинов интерфейс. Мишката PS/2 е свързана към компютъра чрез asix-pinmini-DIN интерфейс, който е много подобен на интерфейса на клавиатурата, така че обръщайте внимание на разграничението, когато го използвате. Интерфейсът на автобусната мишка е в интерфейсната карта на шината; USB мишката е включена директно в USB порта на компютъра чрез USB интерфейс.
Структурна класификация
Мишката може да бъде разделена на механичен тип, опто-механичен тип и фотоелектричен тип според нейния принцип на работа и нейната вътрешна структура.

Theoriginalmouseonlyexistsasatechnicalverificationproduct,andhasnotbeenmass-produced.AfterthemousewasofficiallyintroducedintothePC,thecorrespondingtechnologywasalsoinnovated.Theprincipleofpositioningbasedondifferentresistanceswascompletelyabandonedandreplacedbya"mechanicalmouse"withpuredigitaltechnology.
Differentfromtheoriginalmouse,thebottomofthismechanicalmousedoesnothaveasheet-shapedroundwheelthatisperpendiculartoeachother.Instead,itusesafour-wayrollingcolloidalball.Whentheballrolls,itwilldriveapairofrotatingshafts(X-axisandY-axisrespectively).Attheendoftherotatingshaft,thereisacirculardecodingwheel.Thedecodingwheelisattachedwithametalconductivesheetthatdirectlycontactswiththeelectricbrush..Whentheshaftrotates,thesemetalconductivesheetsandthebrusheswillcomeintocontactwitheachotherinturn,andtherewillbetwoformsof"on"or"off".Theformercorrespondstothebinarynumber"1"andthelattercorrespondstothebinarynumber"0".Next,thesebinarysignalsaresenttothededicatedchipinsidethemouseforanalysisandprocessingandgeneratecorrespondingcoordinatechangesignals.Aslongasthemousemovesontheplane,thesmallballwilldrivetheshafttorotate,whichwillchangetheon-offconditionofthedecodingwheel,andproduceasetofdifferentcoordinateoffsets,whicharereflectedonthescreen,thatis,thecursorcanfollowthemouseMoveandmove.
Comparedwiththeoriginalmouse,thismechanicalmousehasgreatlyimprovedusability,responsesensitivityandaccuracy,andlowmanufacturingcost,makingitthefirstpopularmouseproductinawiderange.However,duetoitspuremechanicalstructure,dustandotherdirtareoftenattachedtothemouse'sX-axisandY-axisandthesmallball,resultinginunsatisfactorypositioningaccuracy.Inaddition,thefrequentcontactofthebrushandthedecodingwheelismoreseverelyworn.Affectedtheservicelifeofthemechanicalmouse.Afterbeingpopularforawhile,itwasreplacedbythesamelow-cost"opticalmouse".Thelatteristheso-called"mechanicalmouse"thatisstillverycommononthemarket.

Inordertoovercometheshortcomingsofpuremechanicalmousethattheaccuracyisnothighandthemechanicalstructureiseasytowear,LogitechsuccessfullydesignedthefirstAnoptical-mechanicalmouse,generallyreferredtoas"opticalmouse".Theopticalmouseisanimprovementonthebasisofapurelymechanicalmouse,andthepositioningaccuracyofthemouseisimprovedbyintroducingopticaltechnology.Likeapurelymechanicalmouse,theopto-mechanicalmousealsohasasmallglueball,andisconnectedtotheXandYshafts.Thedifferenceisthattheopto-mechanicalmousenolongerhasacirculardecodingwheel,insteadithastwoAgratingcodediscwithgratingslits,andtheadditionoflight-emittingdiodesandphotosensitivechips.Whenthemousemovesonthedesktop,therollingballwilldrivethetwogratingcodediscsontheXandYshaftstorotate,andthelightemittedbytheXandYlight-emittingdiodeswillilluminatethegratingcodedisc.Becausethegratingcodedischasgratinggaps,Attherighttime,thelightemittedbythediodecanbedirectlyirradiatedonthedetectionheadcomposedoftwophotosensitivechipsthroughthegratingslit.Ifalightsignalisreceived,thephotosensitivechipwillgeneratea"1"signal,ifnolightsignalisreceived,itwillbesetasasignal"0".Next,thesesignalsaresenttoaspecialcontrolchiptocalculatethecorrespondingcoordinateoffsetanddeterminethepositionofthecursoronthescreen.
Withthisprinciple,theoptical-mechanicalmousegreatlyexceedstheoriginalpuremechanicalmouseintermsofaccuracy,reliability,andresponsesensitivity,andmaintainstheadvantagesoflowcost.Afteritslaunch,itquicklysweptthemarket.Themousewasquicklyreplaced.Itcanbesaidthattherealmouseerastartedwiththeopticalmouse.Ithascontinuedtothisdayandisstillnotover.Mostlow-endmiceonthemarketareofthistype.However,theopto-mechanicalmousealsohasitsinherentdefects:thesmallballatthebottomisnotresistanttodirt.Afteraperiodofuse,thetworotatingshaftswillbecoveredwithdirtandaffectthelightpassingthrough,suchasinsensitivemovementandblockingofthecursor.Therefore,inordertomaintaingoodperformance,theopticalmouserequiresathoroughcleaningoftherollerballandtherotatingshaftatregularintervals.Inadustyenvironment,itisevenrequiredtocleaniteverytwoorthreedays.Inaddition,astheusetimeincreases,theopticalmousecannotmaintaintheoriginalgoodworkingcondition,andtheresponsesensitivityandpositioningaccuracywilldecrease.Durabilityisnotsatisfactory.
Asthenameimplies,anoptical-mechanicalmouseisamousethatcombinesphotoelectricityandmachinery.Onthebasisofamechanicalmouse,themostworn-outcontactbrushanddecodingwheelarereplacedbynon-contactLEDon-beamlightpathcomponents.Whentheballrolls,therollersintheXandYdirectionsdrivethecodedisctorotate.Therearetwosetsoflightemittingdiodesandphotosensitivetransistorsinstalledonbothsidesofthecodedisc.ThelightbeamemittedbytheLEDsometimesshinesonthephotosensitivetransistor,sometimesitisblocked.Thus,apulsesequencewithaphasedifferenceof90°betweenthetwo-stagegroupisgenerated.Thenumberofpulsesrepresentsthedisplacementofthemouse,andthephaserepresentsthedirectionofmousemovement.Duetotheuseofnon-contactcomponents,thewearrateisreduced,therebygreatlyimprovingthelifeofthemouseandincreasingtheaccuracyofthemouse.Theappearanceoftheopticalmouseisnodifferentfromthatofamechanicalmouse,anditisdifficulttodistinguishwithoutopeningtheshellofthemouse.

Thestructureoftheopticalmouseisverydifferentfromalltheaboveproducts.Thereisnoscrollwheelatthebottom,andnoreflectorisneededtoachievepositioning.Itscorecomponentsarelight-emittingdiodes,miniaturecameras,andopticalengines.Andcontrolchip.Whenworking,thelight-emittingdiodeemitslighttoilluminatethesurfaceofthebottomofthemouse,andtheminiaturecameracontinuouslyshootsimagesatacertaintimeinterval.Thedifferentimagesgeneratedduringthemovementofthemousearesenttotheopticalenginefordigitalprocessing,andfinallythedigitalmatrixofthegeneratedimageisanalyzedbythepositioningDSPchipintheopticalengine.Sincetwoadjacentimagesalwayshavethesamefeature,bycomparingthepositionchangeinformationofthesefeaturepoints,themovingdirectionanddistanceofthemousecanbejudged.Theresultofthisanalysisisfinallyconvertedintoacoordinateoffsettorealizethecursorpositioning.

Едно щракване до двойно щракване
Общо казано, щракванията на мишката стават двойни щраквания. Повечето от тях са причинени от неизправности на мишката. Разбира се, може да се дължи и на неправилни настройки. Двойно щракване. Ето защо се препоръчва да проверите преди поправка, като: openthemouse свойства в контролния панел, изберете раздела "бутон на мишката", има три колони и задайте "заключване" в долната част Колона "clicklock" Опитайте да премахнете отметката. Освен това опитайте да свържете мишката към друг компютър. Ако проблемът все още не съществува, това е основно проблем с мишката. Този тип повреда е по принцип малка повреда и поддръжката е относително проста.
Инструменти за поддръжка: отвертка Phillips, парче картон и карфица. Инструментът е доста прост и можем лесно да намерим:
