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.

Sincethedevicedragsalongwirelikeamouse(likeamouse’stail),DouglasEngelbartandhiscolleaguesjokinglycalledit"Mouse"inthelaboratory.HewasIalsothoughtthatthemousemightbewidelyusedinthefuture,sowhenIappliedforthepatent,Inamedit"displaysystemXYpositionindicator",butpeoplefeltthatthename"Mouse"wasmorecordial,sotherewasa"mouse".call.

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.

Theoriginalform

Dr.DouglasandhiscolleagueBillIngriddesignedtheoriginalprototypeofthemousein1963,andmadeitintotheworldonDecember9,1968.Thefirst"mouse",whichusestheresistancechangecausedbythemovementofthemousetorealizethepositioningandcontrolofthecursor.Thestructureoftheoriginalmouseisrelativelysimple.Thebottomisequippedwithtwomutuallyperpendicularsheet-shapedroundwheels(non-spherical).Eachroundwheeldrivesamechanicalrheostat.Whenthemousemoves,itwillchangetheresistancevalueoftherheostat.Iftheappliedvoltageisfixed,theintensityoftheelectricalsignalfedbackbythemousewillchange.Usingthischangedfeedbacksignalparameter,thesystemcancalculateitsdisplacementinthehorizontalandverticaldirections,andthengenerateasetofrandomDynamiccoordinatesthatchangeasthemousemoves.Thisdynamiccoordinatedeterminesthepositionandmovementofthemouseonthescreen,soitcanreplacetheup,down,left,andrightkeysofthekeyboard,allowingtheusertopositionthecursorinvariousplacesonthescreen.Sincetheoriginalmousehadadatacabledraggedatitstail,itlookedlikealittlemouse.Later,peoplesimplycalledit"Mouse",whichistheoriginofthename"Mouse".OnDecember9,1968,apatentwasappliedforitsdesign.

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.

Fromtheoriginalmouse,mechanicalmouse,opticalmouse(opticalmouse,lasermouse)totoday'stouchmouse,mousetechnologyhasgonethroughalongjourneyandfinallyachievedpositiveresults.

Accordingtotheinterfacetype,themousecanbedividedintofourtypes:serialmouse,PS/2mouse,busmouse,andUSBmouse(mostlyopticalmouse).Theserialmouseisconnectedtothecomputerthroughaserialport,andhastwotypes:9-pininterfaceand25-pininterface.ThePS/2mouseisconnectedtothecomputerthroughasix-pinmini-DINinterface,whichisverysimilartothekeyboardinterface,sopayattentiontothedistinctionwhenusingit.Theinterfaceofthebusmouseisonthebusinterfacecard;theUSBmouseisdirectlypluggedintotheUSBportofthecomputerthroughaUSBinterface.

Structuralclassification

Mousecanbedividedintomechanicaltype,opto-mechanicaltypeandphotoelectrictypeaccordingtoitsworkingprincipleanditsinternalstructure.

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.

Opticalmouse

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.

Inthesameeraasthedevelopmentoftheopticalmouse,adigitalopticalmousewithnomechanicalstructureappeared.Theoriginalintentionofdesigningthisopticalmouseistoimprovetheaccuracyofthemousetoawholenewlevel,sothatitcanfullymeettheneedsofprofessionalapplications.Thiskindofopticalmousedoesnothavethetraditionaldesignofrollingball,rotatingshaft,etc.Itsmaincomponentsaretwolight-emittingdiodes,photosensitivechip,controlchipandareflectiveplatewithgrid(equivalenttoadedicatedmousepad).Whenworking,theopticalmousemustmoveonthereflector.TheXandYLEDswillemitlighttoilluminatethereflectorrespectively,andthenthelightwillbereflectedbythereflectorandirradiatedonthephotosensitivechipafterpassingthroughthelensassembly.Thephotosensitivechipconvertsthelightsignalintothecorrespondingdigitalsignalandsendsittothepositioningchipforspecialprocessing,andthengeneratesX-Ycoordinateoffsetdata.

Thiskindofopticalmousehasindeedimprovedinaccuracyindicators,butithasexposedalargenumberofdefectsinsubsequentapplications.Firstofall,theopticalmousemustrelyonthereflector,anditspositiondataisgeneratedentirelybasedonthegridinformationinthereflector.Ifthereflectorisdirtyorworn,theopticalmousecannotdeterminethepositionofthecursor.Ifthereflectorisseverelydamagedorlostinadvertently,theentiremousewillbescrapped;secondly,theuseofopticalmouseisveryinhumane,anditsmovingdirectionmustbeperpendiculartothegridtextureonthereflector,andtheusercannotquicklychangeThecursormovesdirectlyfromtheupperleftcornertothelowerrightcornerofthescreen;thirdly,thecostofanopticalmouseisquitehigh.Thepriceofhundredsofyuanisnotgreattoday,butinthatera,peoplewereonlywillingtopayabout20yuanforthemouse.Capital,thehighpriceoftheopticalmouseseemsunreasonable.Duetoalargenumberofdrawbacks,thisopticalmousehasnotbeenpopular,andatbest,ithasonlybeenusedtoacertainextentinafewprofessionalgraphicsoccasions.However,withthefullpopularityofopticalandmechanicalmice,thisopticalmousehasquicklybeenmarketed.Eliminated.

Althoughtheopticalmousefailedmiserably,thefull-digitalworkingmethod,nomechanicalstructure,andhigh-precisionadvantageshaveattractedtheattentionoftheindustry.Productswithhighprecision,highreliabilityanddurabilityaretechnicallyfeasible.ThefirsttoachieveresultsinthisfieldareMicrosoftandAgilentTechnologies.In1999,Microsoftlaunchedasecond-generationopticalmousecalled"IntelliMouseExplorer".ThismouseusestheIntelliEyeopticalenginedevelopedbyMicrosoftandAgilent.Becauseitusesmoreopticaltechnology,itisalsocalledbytheoutsideworld.Itisan"opticalmouse".

Itnotonlyretainstheadvantagesofhighprecisionandnomechanicalstructureoftheopticalmouse,butalsohashighreliabilityanddurability.Itdoesnotneedtobecleanedduringuseandcanmaintaingoodworkingconditions.AfteritsbirthQuicklyattractedtheattentionoftheindustry.In2000,LogitechalsocooperatedwithAgilenttolaunchrelatedproducts,whileMicrosoftlatercarriedoutindependentresearchanddevelopmentworkandlaunchedthesecond-generationIntelliEyeopticalengineattheendof2001.Inthisway,opticalmiceformtwocampsrepresentedbyMicrosoftandLogitech.AlthoughAgilentTechnologiesalsomastersthecoretechnologyofopticalengines,itdoesnotinvolvethemanufactureofmouseproducts,butprovidesopticalengineproductstothird-partymousemanufacturers.Almostallnon-MicrosoftandLogitech-brandedmiceonthemarketuseitstechnology.

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

Thereisnodoubtthattheopticalmouse,whichintegratesvariousperfectindicators,isdestinedtohaveabrightfuture.Althoughinthefirstfewyears,theopticalmouseisexpensiveandfewpeopleintheconsumermarketareinterestedinit.After2001,thesituationgraduallychanged.Variousmousemanufacturerslaunchedopticalmouseproductsoneafteranother,andconsumersalsorealizeditsadvantages.Sincethen,underthevigorouspromotionofmanufacturers,consumers'perceptionshavegraduallychanged,andthenumberofuserswhospendmoremoneytopurchaseanopticalmousehascontinuedtoincrease.Atthesametime,thetechnologyoftheopticalmouseisalsocontinuouslyadvancing,theresolutionisincreasedto800dpiaccuracy,therefreshrateisashighas6000timespersecond,anditcanbeflexibleandfreeinfiercecompetitivegames,andthecolorblindnessthatplaguesopticalmicehasalsobeenwellresolved..Inadditiontothesmoothmassproductionwork,itscostcontinuestodecline.Youcanbuyaprettygoodopticalmouseforabout100yuan(inexpensiveproductsmayonlycost30to40yuan).Theopticalmousehasenteredanexplosivegrowthinthepasttwoyears.Foralongtime,mostinstalleduserswillregarditastheproductofchoice.Insharpcontrast,theopticalmouseisdeclining,andthemarketshareisshrinking.Althoughthereisstillacertaindemandinthelow-endfield,itisreplacedbytheopticalmouse,andthetendencytowithdrawfromthemarketisveryobvious.

• CorecomponentsWebrieflyintroducedtheworkingprincipleoftheopticalmouse.necessary.Inadditiontothehousing,buttons,andinternalPCBcircuitboard,theopticalmousealsocontainsfourparts:light-emittingdiodes,opticalengines,auxiliarylenscomponents,andcontrolchips.Theyarealsothecorecomponentsoftheopticalmouse.

LightEmittingDiode

Theopticalmouseusesaminiaturecameratocapturedifferentimages.Thepictureisshotatthebottom,itmustbeilluminatedwiththehelpoflight-emittingdiodes.Generallyspeaking,redorbluelight-emittingdiodesaremostlyusedinopticalmice,buttheformerismorecommon.Thereasonisnotthatredlightisgoodforcapturingimages,butthatredlight-emittingdiodeswerebornfirst,withmaturetechnologyandthecheapestprice.Unlikethefirst-generationopticalmouse,theopticalmousedoesnotneedtocapturereflectedlightforpositioning.Theonlypurposeofthelight-emittingdiodeistoilluminate,soitsqualityisnotrelatedtotheactualperformanceofthemouse,itisjustaconventionalcomponent.Itshouldbenotedthatthereisonlyonelight-emittingdiodeintheopticalmouse,andthefirstgenerationofopticalmousehasXandYdiodes,whichisdeterminedbythedifferentworkingprinciplesofthetwo.

OpticalEngine

OpticalEngine(OpticalEngine)isthecorecomponentofanopticalmouse.Itsfunctionislikeahumaneye,constantlycapturingwhatyouseeTotheimageandanalyzeit.TheopticalengineiscomposedofaCMOSimagesensorandanopticalpositioningDSP(digitalsignalprocessor).Theformerisresponsibleforimagecollectionandsynchronizationintoabinarydigitalimagematrix,whiletheDSPisresponsiblefortheanalysisandcomparisonofadjacentimagematrices.Thiscalculatesthepositionoffsetofthemouse.Theopticalmousemainlyhastwoindicatorsofresolutionandrefreshrate,bothofwhicharedeterminedbytheCMOSsensor.However,iftheresolutionandsamplingfrequencyarehigher,theamountofinformationgeneratedbythedigitalmatrixwillincreaseexponentially,andthecorrespondingDSPmustOnlywithcommensuratehardwarecomputingcapabilities.

Althoughthestructureoftheopticalenginedoesnotseemtobecomplicated,onlyMicrosoftandAgilenthavethedesignandmanufacturingcapabilitiesintheworld.Microsoft'sopticalengineisonlyusedinitsownopticalmouseproducts,notforsale,soastoensureitsowntechnologicaladvantages.AndAgilentistakingthesupplierroute,providingsensorproductstomousemanufacturers.AlthoughLogitechplaysanimportantroleinthefieldofopticalmice,itdoesnotdevelopitsownopticalengine,butusesAgilentproducts,butbecauseofitsadvantagesinscale,itcanmonopolizethehigh-endproductlineofAgilentsensors.Logitech'sexistingMX510Theseriesofhigh-endmiceusethe"newMXopticalengine(namedbyLogitech)"producedbyAgilentTechnologies.

3.Lensassembly

Likelight-emittingdiodes,thelensassemblyofanopticalmousealsobelongstothelistofconventionalparts,butitisnecessaryforimagingMissingkeycomponents.Thelensassemblyislocatedatthebottomofthemouse.Itconsistsofaprismandacircularlensconnectedtogether.Prismisresponsibleforrefractingthelightemittedbythelight-emittingdiodetothebottomofthemouseandilluminatingit,whichisanecessaryaidfor"lightoutput".Thecircularlensisequivalenttothecameralens,whichisresponsibleforfocusingthelightofthereflectedimageintothereceivingholeatthebottomoftheopticalengine,whichisequivalenttotheaidof"lightinput".Itisnotdifficulttoseethatprismsandcircularlensesareofequalimportance.Ifweremoveanyofthesecomponents,theopticalmousewillnotworkatall.

Thelenscomponentswillnotdirectlydeterminetheperformanceindicatorsoftheopticalmouse,butlikethelight-emittingdiodes,theirqualitywillaffecttheoperatingsensitivityofthemouse.Ifthequalityofthelensassemblyispoorandthelighttransmissionlossislarge,thesensorwillnotbeabletoobtainaclearimage,andthepositioningchipispronetodeviationwhenjudgingthecursorposition,whilethehigh-qualitylensassemblydoesnothavethisproblem.Generallyspeaking,thelensofanopticalmousecanbemadeofglassandplexiglass,buttheformerisdifficulttoprocessandcostly.Althoughthetransparencyisdifferentfromglass,thelatterhastheadvantagesofgoodplasticity,easyprocessing,andlowcost.Therefore,plexiglasshasbecomethemainmaterialformanufacturingopticalmouselenscomponents.

4.Controlchip

Thecontrolchipcanbesaidtobethenervecenteroftheopticalmouse,butbecausethemaincalculationworkisdeterminedbythepositioningDSPchipintheopticalengineAssumed,thecontrolchipdoesnotneedtoberesponsibleforthispartofthework.Inthisway,itstaskisfocusedoncommandingandcoordinatingthecoordinationofvariouscomponentsintheopticalmouse,andatthesametime,italsoundertakestheI/Ofunctionofconnectingwiththehost.IftheopticalmouseadoptsUSBinterfaceorBluetoothtechnology,thekeyliesinthecontrolchip..Butingeneral,thecontrolchipisalsoaconventionalcomponent,whichhasnoeffectontheactualperformanceoftheopticalmouse.Themousemanufacturercandesignitbyitself.However,apartfromMicrosoft,fewmanufacturersarewillingtodothis,andgenerallyuseitdirectly.Athird-partycompany’sproduct,Logitech’snewMX510seriesusesCypressSemiconductor’sCY7C63743controlchip,whichcombinesaUSB1.1interfaceandaPS/2peripheralcontrollerwith8KEPROM.Inaddition,LogitechalsodesignedaCP5919AMcontrolchipwithAgilentH2000-A0214opticalengine.ItsfunctionissimilartoCypressSemiconductor'sCY7C63743,whichisalsothecurrentpopularsolution.Similarly,ifyouwanttousewirelesstechnologiessuchasinfraredtransmissionandBluetooth,thecontrolchipmustintegratethecorrespondingcontrolfunctions.

5.Opticalengine

Theperformanceofanopticalmouseismainlymeasuredbyresolutionandsamplingfrequency,whicharetheso-calledaccuracyandSpeed,bothareactuallydeterminedbytheopticalengine.Inaddition,thekeyindicatorsoftheopticalenginealsoincludethesizeofthesensor,imageprocessingcapabilitiesandacceleration,etc.,whichalsodeterminetheactualperformanceoftheopticalmouse.

Indexanalysisofopticalmouse

Let’sfirstlookattheresolutionindex.Itisgenerallymeasuredbythedpi(dotsperinch,samplingpointsperinch)index,whichiseasytoItismisunderstoodthatitisconceptuallysimilartotheresolutionofthemonitor.Infact,itisnot.Thecorrectunitoftheresolutionofthemouseshouldbecpi(countperinch,thenumberofmeasurementsperinch),whichreferstoeverymovementofthemouseonthedesktop.Thenumberofpulsesgeneratedbythemouseatadistanceof1inch.Themorepulses,thehigherthesensitivityofthemouse.Thecursormovesthesamelongdistanceonthescreen,andthemousewithhighresolutionmovesashorterdistanceonthedesktop,whichgivespeoplethefeelingof"faster".Foranopticalmouse,theresolutionisdeterminedbytheratioofthediameterofthebottomrollerballtothediameterofthegratingshaftandthenumberofgratinggrids.Thelargertherollingballdiameter,thesmallerthegratingdiameter,andthegreaterthenumberofgratinggrids,thehighertheresolution.Generallyspeaking,thesensitivityofanopticalmouseisbetween300and600cpi,andafewprofessionalproductscanevenreachmorethan2000cpi.Foropticalmice,theresolutiondependsonthesensoritself.Theresolutionofmainstreamopticalmiceis400cpi/800cpi.Whatwemustpayattentiontoisthatthehighertheresolutionofthemouseisnotthebetter,itmustbeconsideredinconjunctionwiththeresolutionofthedisplay.Thehighertheresolutionofthemouse,thefasterthemovementspeedonthescreen.Ifthescreensize/resolutionislow,thecursoronthescreenwillfeelthatthecursorisflyingquicklyandcannotbepositioned.Butifyouareusingahigh-resolution,large-sizescreen,andthemouseresolutionisverylow,itwillbequitedifficulttomovethecursorfromoneendtotheother.Themousehastomovealongdistanceonthedesktop,whichisveryusable.Difference.Frompracticalexperience,ifitisa1024×768resolutionscreen,the400cpi/800cpiindicatorismoresuitable.Ifthescreenresolutionishigherthanthisindicator,an800cpimouseisnecessary.

Samplingfrequencyisauniqueperformanceindexofanopticalmouse.Itreferstotheabilityofthesensortocollect/analyzeimagespersecond,andtheunitis"frame/second".ThesamplingrateofAgilent’searlyH2000opticalengineisonly1500framespersecond,whichmeansthatitcanonlycollectandprocess1500imagesinonesecond.Atthistime,thefastestmovingspeeditcantrackthemouseis14inches/Seconds,ifthemouse'smovingspeedexceedsthisrange,thetrackingwillfailandthecursorwilltemporarilydisappear.Thisdrawbackcausesconsiderabledistresstogameplayers:incompetitivegamessuchasCSandQuake3,playersoftenneedFlickingthemouseatahighspeedof30inches/sec,thesamplingfrequencyof1500frames/secobviouslycannotmeettherequirements.Forthisreason,manypeoplethinkthatopticalmicearenotsuitableforplayinggames,butthedevelopmentofopticalengineslatermadethissceneahistory.

Microsoft’sIntelliEyeopticalenginelaunchedin1999openedthepreludetothepopularityofopticalmice,anditsresolutionreached400cpi,thesamplingfrequencyis1500framespersecond.Thisnumberseemsshabbynow,butitcausedquiteastiratthetime.Intheprocessofproductization,Microsoftfoundthatthelackofsamplingfrequencymadeitdifficulttoadapttotheneedsofcompetitivegames.Forthisreason,thesecond-generationIntelliEyeenginewasdevelopedin2001andisstillinusetoday.Themainimprovementofthesecond-generationIntelliEyeengineistoincreasethesamplingfrequencyto6000framespersecond,andthefastesttrackingspeedcanreach37inchespersecond(thelimitmovingspeedofthehumanhandis30inchespersecond),allowingtheopticalmousetobethecursorwhenplayinggamesThedilemmaoflosshasbecomehistory,andsincethen,opticalmicehavetrulyreplacedtheopticalmouseasthemainstreamchoice.Inaddition,thesensorsizesofthetwogenerationsofIntelliEyeenginesare22×22pixels.Itisnotdifficulttocalculatetheirimageprocessingcapabilitiestobe726,000pixelsand2.904millionpixelspersecond,respectively.

Butintermsofresolution,Microsoftbelievesthat400cpiissufficient,anditisnotnecessarytoincreaseitto800cpi,andithasnotgivenupthisideauntilnow.Inpracticalapplications,the400cpiresolutionperformswell.Afterall,mostusers'displayresolutionsareatthe1024×768level,andtheadvantageofincreasingto800cpiisnotobvious.However,withthepopularizationof17-inchlarge-sizeLCDmonitors,itisageneraltrendtoincreasethemouseresolutionto800cpi.WebelievethatMicrosoftwilllaunchthethird-generationIntelliEyeenginewitharesolutionof800cpiatanappropriatetime.

Agilent’sopticalenginetechnology

Asaleadingmanufacturerofopticalmouseengines,AgilentTechnologieshasarichaccumulationinthisfield.IthassuccessivelylaunchedthreegenerationsofopticalEnginetechnology,butbecauseAgilentdidnotmanufactureitsownmouse,anddidnotgivealoudnametotheopticalengineproduct,itislesswellknown.

TheH2000introducedearlierisAgilent’sfirst-generationproduct,anditsindicatorsareequivalenttoMicrosoft’sfirst-generationIntelliEyeengine,sowewon’trepeatit.Afterthat,Agilenttookadifferentapproachtodevelopingproducts.Itbelievedthatresolutionwasasimportantassamplingfrequency.Thisideawasfullyreflectedinthesecond-generationengine(A2030,A2051)launchedin2001.Thesecond-generationopticalengineslightlyincreasedthesamplingfrequencytothelevelof2300framespersecond,buttheresolutiongreatlyincreasedto800cpi.AlthoughproductsbasedonAgilent'ssecond-generationopticalengineperformwellinaprofessionalgraphicsenvironment,theyareclearlyinferiortoMicrosoft'sproductsincompetitivegames.Afterrealizingthisflaw,Agilentshifteditsfocustoincreasingthesamplingfrequency.Inthesecondhalfof2002,AgilentandLogitechcooperatedtojointlylaunchthe"MXopticalengine".Inadditiontoretainingthehighprecisionof800cpi,the"MXopticalengine"greatlyincreasedthesamplingfrequencyto5220framespersecond,andatthesametimeincreasedtheCMOSsensitivity.Thesizeofthemonitorhasbeenincreasedfrom22×22pixelsto30×30pixels,sothatthe"MXopticalengine"hasanimageprocessingcapacityofupto4.7millionpixelspersecond,andtheoveralltechnicalspecificationshaveslightlyexceededthatofMicrosoft'scontemporaries.

ThelatesttechnologicalimprovementwasinJune2004.OnLogitech’snewMX510mouse,weweresurprisedtofindthatthe"MXopticalengine"wasdevelopedtothesecondgeneration.Thesecond-generationMXenginehasonceagainincreasedthesamplingfrequencytoanastonishinglevelof6,500frames,anditsimageprocessingcapabilityhasalsobeenfurtherincreasedtoanastonishinglevelof5.85millionpixelspersecond,whichcanbecalledthepinnacleofopticalmousetechnology.Itisnotdifficulttoseethatatthistime,Agilent-Logitechisleadingthewayinenginetechnology.Althoughtheadvantagesarenotobviousinpracticaluse,itcanundoubtedlyaffectconsumers’choices.Facedwithsuchpressure,Microsoftdoesnotlaunchnewproductsintime.Theresponseseemsunreasonable.Ofcourse,theopticalengineisonlyacomponentofthemouse,anddoesnotreflecttheoperatingfeelofthemouse.Inmanycases,aproductwithascientificdesignandbeautifulappearanceisoftenmoreattractivethanapureperformanceadvantage.

Severalproblemsintheuseofopticalmice

Youusuallyfindthefollowingproblemsintheprocessofusingopticalmice:glass,metal,etc.Themousecan’tworknormallyonsmoothsurfacesoronsomespecial-coloredsurfaces.Thecursorappearstobestuck,trembling,driftingorunresponsive,orevenmissingthecursor.Thesetwoproblemshavebeensolvedwiththedevelopmentofscienceandtechnology.Logitechreleasedin09The"Unbounded"technologylaunchedin1988andthe"WinningLaser"technologylaunchedbyShuangfeiyanin10yearscanmakethemouserununimpededontheglasssurface.Whydoestheoldopticalmousehavetheaboveproblems?Thefundamentalreasonliesinthelimitationoftheinnateprincipleoftheopticalmouse,wemaywishtomakefurtheranalysisonthis.

Weknowthattheopticalengineoftheopticalmousedeterminesthepositionofthecursorbyreceivingthefeedbackimage.Ifthemovingsurfaceistoosmooth,itmaynotproduceenoughdiffuselight,sothereflectionreceivedbythesensorThelightintensityisveryweak,sothatthepositioningchipcannotbedistinguished,whichcausestheembarrassmentofthemousenotworkingproperly.However,theglassmousepadsandmetalmousepadsonthemarketarenotmadeofsmoothsurfaces,butfrosted.Thediffuseemissionconditionsaregood,buttherearestillmanyopticalmouseproductsthatcannotworkonthem.Thisinvolvesanotherreason.Weknowthatthepositioningchipjudgesthepositioninformationofthecursorbycomparingthedifferencebetweenthefeaturepointsontheadjacentimagematrix,andthemattesurfaceofsomeglassmousepadsandmetalmousepadsismadequitefine.Thesurfaceishighlyconsistent.Ifitisatraditionalopticalmouse,itcanbesaidtomovelikeflyingandhandy,butthisisnotthecaseforanopticalmouse.Thehighlyconsistentsurfacecausesthedifferencebetweendifferentfeaturepointstobetoosmall.Thesensorcannotreflectthedifferenceafterconvertingitintoadigitalsignal.Itisnaturallydifficultforthepositioningchiptocompareandprocess,resultinginamouseataloss.Naturally,youshouldnotexpectittobeabletoItworksnormally.However,sensormanufacturerscanalleviatethisproblembyincreasingthesizeoftheCMOSsensor.Thelargerthesizeofthephotoreceptor,thehighertheresolutionaccuracyofthecapturedimage,andthegreaterthenumberoffeaturepoints,themorefeaturepointscanbecomparedwiththepositioningchip,sothatamoreaccuratejudgmentcanbemade.Ofcourse,theincreaseinthesizeofthesensormeansthattheamountofinformationtobeprocessedismore,andthecomputingpowerofthepositioningchipmustbesimultaneouslyimproved.Therepresentativeofthistechnicalsolutionisthe"MXopticalpositioningengine"ofAgilentTechnologies.Thesensorspecificationofanordinarymouseis22×22pixels,whilethe"MXopticalpositioningengine"isincreasedto30×30pixels,andtheamountofinformationthatcanbecapturedAnincreaseof80%.

Fortheproblemthattheopticalmousedoesnotworkoncertaincoloredsurfaces(alsoknownas"colorblindness"),theanswerissimilartotheabovesituation.Theopticalenginerealizescursorpositioningbytakingimagesandcomparingthedifferences.Totakeimages,thesensorisrequiredtocapturethereflectedlightwithacertainintensityanduniformdiffusereflection.However,mostsensorscanonlysensesomespecificwavelengthsofcoloredlight,andcannotdoanythingwithotherwavelengthsofcoloredlight.Ifthesurfaceofthemousepadcanabsorbalargeamountofthecolorlightthatthesensorcansense,theintensityofthecolorlightreflectedbackisinsufficient,andthesensorcannoteffectivelysenseit.Naturally,itisimpossibletocalculatethespecificpositionofthecursor.However,"colorblindness"isnotadefect.Usersonlyneedtochooseamousepadwithasuitablecolor.Ifthemousemanufacturermakesalleffortstosolvethisproblem,itmaycostahighercost.
