I-Vision Pro yakhiwe ngokulandela ukulandelela ngesandla kuyilapho i-Quest 3 isebenzisa izilawuli kuqala nokubaluleke kakhulu, kodwa futhi isekela ukulandelela ngesandla njengenye inketho yokunye okuqukethwe. Kodwa yikuphi okunokulandelela okungcono ngesandla? Ungase umangale ngempendulo.

I-Vision Pro Hand-tracking Latency

Ngaphandle kokusekelwa kwezilawuli ezinyakazayo, okokufaka okusekelwe enyakazweni kwe-Vision Pro kuphela wukulandelela ngesandla. Isistimu yokufaka eyinhloko ihlanganisa izandla namehlo ukuze ilawule yonke i-interface.

Ngaphambi kokwethulwa kwama-headset we ibone izithombe ezisivumela ukuthi silinganise i-latency yokulandelela ngesandla phakathi kuka-100-200ms, kodwa iwindi elikhulu kakhulu lelo. Manje sesihlole okwethu futhi sithole ngokunembe kakhudlwana Ukulandelela ngesandla kwe-Vision Pro cishe kube ngu-128ms ku-visionOS beta v1.1.1.

Nansi indlela esiyilinganise ngayo. Sisebenzisa ukuthwebula kwesikrini okuvela kumahedisethi abuka kokubili isandla sokudlula kanye nesandla esibonakalayo, singabona ukuthi kuthatha ozimele abangaki phakathi kokuthi isandla sokudlulisa sihamba nalapho isandla esibonakalayo sinyakaza. Sisebenzise uhlelo lwe-Apple's Persona ukuze sinikeze ngesandla ukuze siqede noma yikuphi ukubambezeleka okwengeziwe okungase kwethulwe yi-Unity.

Ngemva kokuthatha isampula yokuhlola (i-pun ehlosiwe), sithole ukuthi lokhu kungamafreyimu angaba ngu-3.5. Ngesilinganiso sokuthwebula esingu-30 FPS, lokho kungu-116.7ms. Bese sengeza kuleyo Vision Pro's i-passthrough latency eyaziwayo cishe ngo-11ms, ngomphumela wokugcina we-127.7ms we-photon ekubambeni kokulandelela ngesandla.

Siphinde sahlola ukuthi isikhathi esingakanani phakathi kokuthepha okudlulayo nokokufaka okubonakalayo (ukubona ukuthi ukulandelela ngesandla okugcwele kohlaka lwamathambo kuhamba kancane kunokutholwa kokuthepha okulula), kodwa asizange sithole umehluko obalulekile ekubambezelekeni. Siphinde sahlola ezimeni ezihlukene zokukhanyisa futhi asitholanga mehluko obalulekile.

I-Qust 3 Ukulandela ngomkhondo ngesandla Ukubambezeleka

Lokho kuqhathaniswa kanjani ne-Quest 3, ihedisethi engalawulwa yizandla kuphela? Ukusebenzisa ukuhlolwa okufanayo, sithole ukubambezeleka kokulandela ngesandla kwe-Quest 3 cishe kungama-70ms ku-Quest OS v63. Lokho kuwukuthuthuka okukhulu kune-Vision Pro, kodwa ukusetshenziswa kwangempela kwehedisethi kungenza umuntu acabange ukuthi i-Quest 3 inakho. ngisho ngaphansi ukubambezeleka kokulandelela ngesandla. Kepha kuvele ukuthi okunye okubonwa ukuthi i-latency ifihliwe.

Nansi indlela esithole ngayo. Sisebenzisa ukuthwebula kwe-240Hz ngokusebenzisa i-lens, senze uhlobo olufanayo lokuhlola ukunyakaza njengoba senza nge-Vision Pro ukuze sithole ukuthi isikhathi esingakanani phakathi kokunyakaza kwesandla sokudlula kanye nesandla esibonakalayo. Lokho kuphume ku-31.3ms. Kuhlanganiswe ne-Quest 3's i-passthrough latency eyaziwayo cishe ngo-39ms lokho kwenza i-photon ye-Quest 3 ibe yi-latency yokulandelela ngesandla ibe ngu-70.3ms.

Uma usebenzisa i-Quest 3, ukulandelela ngesandla kuzwakala kushesha nakakhulu kunalokho okushiwo yilo mphumela, ngakho-ke yini enikezayo?

Ngoba ukubambezeleka kokudlula kwe-Quest 3 cishe kuphindwe kathathu nesigamu kune-Vision Pro (11ms vs. 39ms), isikhathi esiphakathi kokubona isandla sakho sinyakaza nokunyakaza kwesandla sakho okubonakalayo. kubonakala sengathi 31.3ms nje (uma kuqhathaniswa no-116.7ms ku-Vision Pro).

Iphuzu elibalulekile lapha: ukubambezeleka nokunemba kokulandelela ngesandla kuyizinto ezimbili ezihlukene. Ezimweni eziningi, bangase babe nobuhlobo obuphambene. Uma ulungiselela i-algorithm yakho yokulandelela ngesandla ukuze uthole isivinini, ungase uyeke ukunemba okuthile. Futhi uma uyilungiselela ngokunemba, ungase uyeke isivinini esithile. Njengamanje asinaso isilinganiso esihle sokulandela ngomkhondo ngesandla Ukunemba kunoma iyiphi ihedisethi, ngaphandle komzwelo wamathumbu.
