\nCe-ar fi dac\u0103 am putea lua toate beneficiile dispozitivelor mobile XR \u0219i le-am combina cu performan\u021ba sistemelor XR bazate pe PC? Gadgeturile mobile pentru realitate augmentat\u0103 sunt viitorul XR, deoarece pot fi folosite oriunde \u0219i oric\u00e2nd, f\u0103r\u0103 preg\u0103tire prealabil\u0103 \u0219i f\u0103r\u0103 cabluri. Implementarea XR pe baz\u0103 de PC, de\u0219i nu poate fi considerat\u0103 viitorul realit\u0103\u021bii augmentate, are un avantaj important \u2013 nu este restric\u021bionat\u0103 de puterea consumat\u0103 \u0219i eficien\u021ba sistemului de r\u0103cire, ceea ce, la r\u00e2ndul s\u0103u, permite realizarea unor calculuri mai intensive.

Cre\u0219terea eficien\u021bei proces\u0103rii datelor de realitate augmentat\u0103 pe dispozitiv
\n<\/h3>\n

\nLucrul cu grafica \u00een sistemele de realitate extins\u0103 necesit\u0103 o putere de calcul mare \u0219i este sensibil la timpul de r\u0103spuns. Pentru o separare corect\u0103 a calculului, este nevoie de o abordare sistematic\u0103. S\u0103 analiz\u0103m cum utilizarea calculului de margine \u00een cloud poate ajuta la completarea mai eficient\u0103 a proces\u0103rii pe dispozitiv, cre\u00e2nd sisteme de realitate extins\u0103 f\u0103r\u0103 limite cu grafic\u0103 fotorealist\u0103 (informa\u021bii mai detaliate sunt disponibile \u00een webinarul nostru webinar<\/a><\/noindex>).<\/p>\n

C\u00e2nd un utilizator al sistemului XR \u00ee\u0219i rote\u0219te capul, procesarea pe dispozitiv determin\u0103 pozi\u021bia capului \u0219i trimite aceste date \u00een cloudul de calcul de margine printr-un canal 5G cu \u00eent\u00e2rziere minim\u0103 \u0219i un nivel ridicat de calitate a serviciului. Acest sistem utilizeaz\u0103 datele primite despre pozi\u021bia capului pentru a efectua un rendering par\u021bial al urm\u0103rii cadre, a codifica datele \u0219i a le trimite \u00eenapoi la c\u0103\u0219tile XR. C\u0103\u0219tile decodeaz\u0103 apoi ultimul pachet primit \u0219i, folosind datele actualizate \u00een mod regulat despre modific\u0103rile pozi\u021biei capului, continu\u0103 vizualizarea \u0219i ajustarea imaginii pentru a minimiza procentul de laten\u021b\u0103 motion-to-photon (\u00eent\u00e2rzierea dintre schimbarea pozi\u021biei capului utilizatorului \u0219i schimbarea imaginii \u00een c\u0103\u0219ti). S\u0103 reamintim c\u0103, conform acestui indicator, toat\u0103 procesarea trebuie s\u0103 fie finalizat\u0103 \u00eentr-un interval de timp ce nu dep\u0103\u0219e\u0219te 20 de milisecunde. Dep\u0103\u0219irea acestui prag duce la senza\u021bii nepl\u0103cute pentru utilizator \u0219i la sc\u0103derea nivelului de imersiune \u00een realitatea augmentat\u0103.<\/p>\n

\"Tehnologiile
\nCalculul pe dispozitiv este completat prin calculul de margine \u00een cloud \u0219i canalul 5G cu timp de r\u0103spuns redus.
\n<\/i>
\nDup\u0103 cum pute\u021bi observa, pentru a ob\u021bine un efect de imersie de calitate \u00een XR, este necesar\u0103 o solu\u021bie sistematic\u0103 cu un timp de r\u0103spuns sc\u0103zut \u0219i fiabilitate ridicat\u0103, astfel \u00eenc\u00e2t re\u021belele 5G, cu \u00eent\u00e2rzierea lor minim\u0103 \u0219i l\u0103\u021bimea de band\u0103 mare, reprezint\u0103 un element critic al XR. Pe m\u0103sur\u0103 ce re\u021belele 5G se \u00eembun\u0103t\u0103\u021besc \u0219i acoperirea lor cre\u0219te, utilizatorii vor putea s\u0103 se bucure de grafica fotorealist\u0103 \u00een aplica\u021biile XR \u00een multe locuri \u0219i vor fi siguri c\u0103 experien\u021ba premium autonom\u0103 XR va r\u0103m\u00e2ne accesibil\u0103 datorit\u0103 calculului eficient pe dispozitiv.<\/p>\n

\u0218i acesta este un aspect cheie pe care merit\u0103 s\u0103-l subliniem din nou: procesarea datelor pe dispozitiv r\u0103m\u00e2ne un factor extrem de important \u00een orice scenariu. \u00cen mod autonom, computa\u021bia \u201ela bord\u201d pe dispozitiv este responsabil\u0103 pentru toate calculele legate de XR. Colabor\u00e2nd cu sistemul de computa\u021bie cloud de tip edge, procesarea \u201ela bord\u201d va oferi c\u0103\u0219tilor XR capacitatea de vizualizare \u0219i tracking eficient din punct de vedere energetic \u0219i de \u00eenalt\u0103 performan\u021b\u0103, cu laten\u021b\u0103 redus\u0103.<\/p>\n

\nQualcomm Technologies lucreaz\u0103 deja la dezvoltarea solu\u021biilor mobile XR autonome de \u00eenalt\u0103 performan\u021b\u0103 \u0219i r\u0103m\u00e2ne lider \u00een promovarea tehnologiilor 5G<\/a><\/noindex> la nivel global. Dar nu putem transforma ideile noastre despre XR \u201ef\u0103r\u0103 limite\u201d \u00een realitate pe cont propriu. Colabor\u0103m activ cu cei mai mari reprezentan\u021bi ai ecosistemelor XR \u0219i 5G, inclusiv produc\u0103tori OEM \u0219i creatori de con\u021binut, furnizori de servicii \u0219i infrastructur\u0103, deoarece arhitectura de rendering separat este o solu\u021bie sistemic\u0103.<\/p>\n

\"Tehnologiile

\nCa urmare a sinergiei, to\u021bi participan\u021bii ecosistemului XR vor beneficia de dezvoltarea activ\u0103 a acestuia, iar numele acestei beneficii este \u201ecre\u0219terea adopt\u0103rii de c\u0103tre consumatori\u201d. De exemplu, operatorii de telecomunica\u021bii vor ob\u021bine anumite beneficii din transformarea Wireless Edge \u00een ansamblu, dar s\u0103 ne concentr\u0103m pe beneficiile specifice de la dezvoltarea XR f\u0103r\u0103 limite. \u00cen primul r\u00e2nd, odat\u0103 cu apari\u021bia re\u021belelor 5G, l\u0103\u021bimea de band\u0103 \u00eembun\u0103t\u0103\u021bit\u0103 va cre\u0219te capacitatea, va reduce timpul de r\u0103spuns \u0219i va asigura un nivel garantat de servicii, ceea ce va permite apari\u021bia unor aplica\u021bii XR mai bogate \u0219i mai interactive. \u00cen al doilea r\u00e2nd, pe m\u0103sur\u0103 ce operatorii \u00ee\u0219i vor cre\u0219te capacit\u0103\u021bile pentru computa\u021bia cloud de tip edge, vor putea oferi utilizatorilor de baz\u0103 servicii complet noi, cum ar fi aplica\u021bii XR cu grafic\u0103 fotorealist\u0103.<\/p>\n
