TheWiiisahomevideogameconsolereleasedby NintendoonNovember19,2006,asaseventh generationconsole.Adistinguishingfeatureofthe consoleisitswirelesscontroller,theWiiRemote,which canbeusedasahandheldpointingdeviceanddetects movementinthreedimensions. Theconsolewasknownbythecodenameof"Revolution"untilApril27,2006.TheNintendo StyleGuidereferstotheconsoleas"simplyWii,notNintendoWii",makingitthefirsthome consoleNintendohasmarketedoutsideofJapanwithoutthecompanynamefeaturedinits trademark.While"Wiis"isacommonlyusedpluralizationoftheconsole,Nintendohasstated thattheofficialpluralformis"Wiisystems"or"Wiiconsoles".Nintendo'sspellingof"Wii"with twolower‐case"i"charactersismeanttoresembletwopeoplestandingsidebyside, representingplayersgatheringtogether,aswellastorepresenttheWiiRemote.Thecompany hasgivenmanyreasonsforthischoiceofnamesincetheannouncement;however,thebest knownis: “Wiisoundslike'we',whichemphasizesthattheconsoleisforeveryone.Wiicaneasily berememberedbypeoplearoundtheworld,nomatterwhatlanguagetheyspeak.No confusion.Noneedtoabbreviate.JustWii.” TheWiiisNintendo'ssmallesthomeconsoletodate;itmeasures44mmwide,157mmtall and215.4mmdeepinitsverticalorientation.Thesystemweighs1.2kg,whichmakesitthe lightestofthethreemajorseventhgenerationconsoles.Theconsolecanbeplacedeither

Finally,thestudentdesignedalighttransmitter,sotheglassesandtheglovesdidnotneed giveoutlight,theyneededtoreflectthelightemitted.  Development
