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.

Vzhledem k tomu, že se zařízení táhne po drátě jako myš (jako myší ocas), Douglas Engelbart a jeho kolegové ho v laboratoři vtipně nazývali „Myš“. byl srdečnější,sotherebyl"myš".hovor.

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.

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.

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.

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

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.

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.
