Adamu Kos ʻAʻole hoʻohana nā smartphones a pau i ka ʻenehana wehe maka like. ʻOi aku ka palekana o kekahi, ʻoi aku ka liʻiliʻi. ʻO kekahi ma 3D, ʻo kekahi ma 2D. Eia nō naʻe, ʻoiai me ka ulu nui o ka palekana, pono ʻoe e ʻike ʻaʻole i hana like nā hoʻokō ʻike maka a pau.
ʻIke maka me ka hoʻohana ʻana i ka pahupaʻikiʻi
E like me ka hōʻike ʻana o ka inoa, hilinaʻi kēia ʻenehana i nā kāmela mua o kāu kelepona e ʻike ai i kou helehelena. Ma kahi o nā kelepona Android āpau i hoʻokomo i kēia hiʻohiʻona mai ka hoʻokuʻu ʻia ʻana o ka Android 4.0 Ice Cream Sandwich ma 2011, kahi lōʻihi ma mua o ka hiki ʻana mai o Apple me kāna Face ID. He maʻalahi loa ke ʻano o ka hana. Ke hoʻā ʻoe i ka hiʻohiʻona no ka manawa mua, koi kāu kelepona iā ʻoe e kiʻi i nā kiʻi o kou alo, i kekahi manawa mai nā kihi ʻokoʻa. A laila hoʻohana ia i kahi polokalamu algorithm e unuhi i kou mau hiʻohiʻona a mālama iā lākou no ka ʻike e hiki mai ana. Mai kēia manawa, i kēlā me kēia manawa e ho'āʻo ai ʻoe e wehe i ka hāmeʻa, hoʻohālikelike ʻia ke kiʻi ola mai ke kāmela mua me ka ʻikepili kuhikuhi.
Aia ka pololei i ka polokalamu algorithms i hoʻohana ʻia, no laila mamao loa ka ʻōnaehana mai ka hemolele. ʻOi aku ka paʻakikī i ka wā e noʻonoʻo ai ka hāmeʻa i nā ʻano like ʻole e like me nā kūlana kukui like ʻole, nā loli i ka helehelena o ka mea hoʻohana a me ka hoʻohana ʻana i nā mea e like me nā aniani a me nā mea nani. ʻOiai ʻo Android ponoʻī e hāʻawi i kahi API no ka ʻike maka, ua hoʻomohala nā mea hana kelepona i kā lākou mau hopena i nā makahiki. Ma ke ʻano holoʻokoʻa, ʻo ka pahuhopu ka hoʻomaikaʻi ʻana i ka wikiwiki o ka ʻike ʻana me ka ʻole e kaumaha nui i ka pololei.

Vratislav Holub ʻO ka ʻike maka ma muli o ka radiation infrared
Pono ka ʻike maka infrared i ka lako kamepiula hou. Eia nō naʻe, ʻaʻole i hana like nā hoʻonā ʻike maka infrared a pau. ʻO ke ʻano mua e pili ana i ka lawe ʻana i ke kiʻi ʻelua-dimensional o kou helehelena, e like me ke ʻano ma mua, akā ma ka spectrum infrared. ʻO ka pōmaikaʻi nui, ʻaʻole pono nā kāmela infrared i kou maka e hoʻomālamalama maikaʻi ʻia a hiki ke hana i nā wahi mālamalama. ʻOi aku ka maikaʻi o lākou i ka hoʻāʻo ʻana no ka mea hoʻohana nā kāmela infrared i ka ikehu wela e hana i ke kiʻi.
ʻOihana ID
ʻOiai ua lele mua ka ʻike maka infrared 2D ma mua o nā hana kuʻuna e pili ana i nā kiʻi kamera, aia kahi ala ʻoi aku ka maikaʻi. ʻO ia, ʻoiaʻiʻo, ʻo Apple's Face ID, e hoʻohana ana i kahi ʻano o nā mea ʻike e hopu i kahi hiʻohiʻona ʻekolu o kou alo. Hoʻohana ʻia kēia ʻano hana i ka pahupaʻikiʻi mua ma kahi hapa wale nō, no ka mea, loaʻa ka hapa nui o ka ʻikepili e nā mea ʻike ʻē aʻe e nānā ana i kou alo. Hoʻohana ʻia kahi mea hoʻomālamalama, kahi mea hoʻoheheʻe kiko infrared a me kahi pahupaʻikiʻi infrared ma ʻaneʻi.
Hoʻomālamalama mua ka mea hoʻomālamalama i kou maka me ke kukui infrared. Hoʻokumu ka mea hope i kahi palapala ʻāina hohonu o kou alo a no laila e loaʻa ai ka ʻikepili maka pololei. A laila loiloi ʻia nā mea āpau e ka neural engine, e hoʻohālikelike ana i kēlā palapala ʻāina me ka ʻikepili i hopu ʻia i ka wā e hoʻāla ʻia ai ka hana.
He kūpono ka wehe ʻana i ke alo, akā ʻaʻole paʻa paha
ʻAʻohe hoʻopaʻapaʻa ʻo ka ʻike maka 3D me ka hoʻohana ʻana i ke kukui infrared ke ala palekana loa. A ʻike ʻo Apple i kēia, ʻo ia ke kumu, ʻoiai ka huhū o nā mea hoʻohana he nui, mālama lākou i ka ʻokiʻoki i ka hōʻike ma kā lākou iPhones a hiki i ko lākou ʻike ʻana i kahi a pehea e hūnā ai i kēlā me kēia. A no ka mea ʻaʻole ʻaʻahu ʻia nā ʻokiʻoki i ka honua o Android, ʻo ka ʻenehana mua e hilinaʻi wale ana i nā kiʻi wale nō ka mea maʻamau ma aneʻi, ʻoiai ua hoʻohui ʻia e nā algorithms akamai. ʻOiai, ʻaʻole e ʻae ka hapa nui o nā mea hana o ia mau mea iā ʻoe e hoʻohana iā ia no nā noi koʻikoʻi. ʻO ia ke kumu i ka honua o Android, no ka laʻana, ʻoi aku ka paona o ka ʻenehana o ka mea heluhelu manamana lima ultrasonic ma lalo o ka hōʻike.
Manaʻo iPhone me ka Touch ID ma lalo o ka hōʻike
No laila, ma ka ʻōnaehana Android, hoʻonohonoho ka papahana hōʻoia lawelawe kelepona Google i nā palena palekana liʻiliʻi no nā ʻano hana hōʻoia biometric. ʻO nā mīkini wehe paʻa liʻiliʻi, e like me ka wehe ʻana i ka maka me ka pahupaʻikiʻi, a laila helu ʻia ma ke ʻano he "maʻalahi". ʻO ka waiho wale ʻana, ʻaʻole hiki ke hoʻohana ʻia no ka hōʻoia ʻana i nā noi koʻikoʻi e like me Google Pay a me nā inoa panakō. Hiki ke hoʻohana ʻia ka Face ID o Apple e laka a wehe i kekahi mea, a me ka uku pū me ia, etc.
Ma nā smartphones, hoʻopili maʻamau ʻia ka ʻikepili biometric a hoʻokaʻawale ʻia i nā lako palekana palekana i loko o ka system-on-chip (SoC) o kāu kelepona. ʻO Qualcomm, kekahi o nā mea hana nui loa o nā chips no nā smartphones me ka ʻōnaehana Android, aia kahi Secure Processing Unit i kāna SoCs, Samsung he Knox Vault, a ʻo Apple, ma kekahi ʻaoʻao, he Secure Enclave subsystem.

I hala a me ka wā e hiki mai ana
ʻO nā hoʻokō e pili ana i ke kukui infrared ua lilo i mea maʻalahi i nā makahiki i hala iho nei, ʻoiai ʻo ia ka mea palekana loa. Ma waho aʻe o iPhones a me iPad Pros, ʻaʻole i loaʻa i ka hapa nui o nā smartphones nā mea ʻike pono. I kēia manawa ua maʻalahi ke kūlana, a ʻike maopopo ʻia e like me kahi hopena Apple. Eia nō naʻe, aia kekahi manawa i loaʻa i nā polokalamu Android he nui, mai ka waena waena a i nā hae hae, i ka lako pono. No ka laʻana, ua hiki i ka Samsung Galaxy S8 a me S9 ke ʻike i ka iris o ka maka, hāʻawi ʻo Google i ka wehe ʻana i ka maka i kapa ʻia ʻo Soli i kāna Pixel 4, a ua loaʻa pū ka wehe ʻana i ka maka 3D ma ke kelepona Huawei Mate 20 Pro. Akā ʻaʻole ʻoe makemake i kahi ʻoki? ʻAʻole loaʻa iā ʻoe nā mea ʻike IR.
Eia nō naʻe, ʻoiai kā lākou wehe ʻia ʻana mai ka Android kaiaolaola, hiki ke hoʻi mai ka ʻike maka kiʻekiʻe i kekahi manawa. ʻAʻole wale nā mea ʻike manamana lima akā ʻo nā kāmera ma lalo o ka hōʻike. No laila, he manawa wale nō ma mua o ka loaʻa ʻana o ka mālama like ʻana o nā mea ʻike infrared. A i kēlā manawa e ʻōlelo maikaʻi mākou i nā ʻokiʻoki no ka maikaʻi, ma Apple paha.
ʻAe, e ʻōlelo wau ʻaʻole pono ʻo Android e hana i kēia, no ka mea, ʻaʻole ia i wehe i kāna mau manamana lima a ʻaʻole ia e koi i kekahi e hoʻohana i kēlā ʻano demented.
