$L(t) = [H(e_i), S(e_i), V(e_i, t), f(e_i), w(e_i, t)]$

Inda:

$H$: Launi (madaidaicin tsawon zango, wanda aka taswira daga ilimin halayyar launi).
$S$: Jikewa (tsarkin launi, misali, babba don hankali mai ƙarfi).
$V$: Ƙima/Haske, aikin lokaci da hankali: $V(t) = A(e_i) \cdot w(2\pi f(e_i) t) + V_{base}(e_i)$. $A$ shine amplitude, $w$ shine aikin siffar igiyar ruwa (sine, square), $f$ shine mita.
$f$: Mita na lokaci na tsarin.
$w$: Aikin siffar igiyar ruwa wanda ke ayyana siffar tsarin akan lokaci.

Misali, fushi ($e_a$) ana iya siffanta shi kamar: $H_{a} \approx 0\text{° (Ja)}, S_{a} \approx 1.0, V_{a}(t) = 0.8 \cdot \text{square}(2\pi \cdot 5 \cdot t) + 0.2, f_{a}=5\text{Hz}$.

6. Babban Fahimta & Ra'ayi na Manazarta

Babban Fahimta: Wannan takarda ba game da gina mafi kyawun fuskar hankali ba ce; hack ne mai amfani ga tattalin arzikin mutum-mutumi "marar fuska". Ta nuna cewa ga mutane-mutumi na kasuwa mai yawa, masu kula da farashi (tunanin bots na sito, mataimakan gida masu sauƙi), grid ɗin LED na $5 zai iya cimma 70% na gane hankali na fuskar mutum-mutumi na $50,000 don yanayi na asali kamar farin ciki da fushi. Ainihin ƙimar shawarar ita ce bandwidth na hankali kowace dala.

Kwararar Ma'ana: Hujja tana da tsabta da masana'antu: 1) Fuska masu rikitarwa suna da tsada kuma suna da nauyi na lissafi (sun ambaci Geminoid, KOBIAN). 2) Alamun marasa magana suna da mahimmanci don karɓar HRI. 3) Hasken yana da araha, ana iya shirya shi, kuma ana iya gane shi a duniya. 4) Bari mu taswira ainihin hankali zuwa mafi sauƙaƙan ma'auni na haske (launi, walƙiya). 5) Gwada ko yana aiki. Kwararar ba ta da zurfi game da zurfin tunani kuma ta fi ƙarfin ƙirar injiniya don mafi ƙarancin samfurin da zai iya aiki (MVP) a cikin bayyanar hankali.

Ƙarfi & Kurakurai: Ƙarfinsa shine amfaninsa na zahiri da kuma tabbatar da gwaji mai haske don hankali mai tashin hankali. Yana ba da ƙayyadaddun bayanai masu amfani ga masu ƙira na mutum-mutumi. Laifin, wanda marubutan suka yarda da shi, shine palet ɗin hankali mara zurfi. Rashin Tsoro yana ba da labari—yana bayyana iyakancewar hanyar da ba ta da ma'ana (launi + saurin walƙiya) ba tare da mahallin ma'ana ba. Kamar yadda aka lura a cikin aikin lissafin hankali na asali na Picard (1997), ainihin sadarwar hankali sau da yawa tana buƙatar kimantawa da mahallin, wanda tsiri na haske ya rasa. Idan aka kwatanta da ƙarin ingantattun, samfuran samarwa don bayyanawa kamar waɗanda aka tattauna a cikin takardar CycleGAN (Zhu et al., 2017) don canja wurin salo, wannan hanyar tana da tabbatacce kuma ba ta da daidaitawa.

Fahimta Mai Aiki: Ga manajoji samfur: Ai wannan don sanar da yanayin asali (aikin da aka yi = bugun kore mai farin ciki, kuskure = walƙiyar ja mai fushi) a cikin mutane-mutumi marasa zamantakewa nan da nan. Ga masu bincike: Gaba ba ya cikin inganta wannan taswirar tsayayye ba, amma a sanya ta daidaitawa. Yi amfani da martanin ilimin halittar mai amfani (ta hanyar kyamara ko sawa) a cikin madauki da aka rufe don daidaita tsarin a ainihin lokacin, matsawa zuwa tsarin "kamar CycleGAN" wanda ke koyon taswirar hankali na keɓance. Haɗin gwiwa tare da ƙungiyoyin AR/VR—wannan fasaha ta dace don nuna yanayin hankali na wakilan AI da ba a iya gani a cikin nunin kai.

7. Tsarin Bincike & Misalin Hali

Tsari: Tsarin Ƙarfin Tashar Hankali (ACC)
Muna ba da shawarar tsari mai sauƙi don kimanta irin waɗannan tsarin: Ƙarfin Tashar Hankali. Yana auna yawan yanayin hankali da tashar (kamar nunin LED) za ta iya isar da su ga mai kallo na ɗan adam cikin aminci a cikin takamaiman taga lokaci. $ACC = log_2(N_{amintacce})$, inda $N_{amintacce}$ shine adadin hankalin da aka gane da mahimmanci sama da dama.

Binciken Misalin Hali: Yin amfani da ACC ga sakamakon wannan takarda:

Farin Ciki: An gane shi cikin aminci.
Fushi: An gane shi cikin aminci.
Baƙin Ciki: Amintacce a gefe (iyakar mahimmanci).
Tsoro: Ba amintacce ba.

Don haka, $N_{amintacce} \approx 2.5$. $ACC \approx log_2(2.5) \approx 1.32$ bits. Wannan yana ƙididdige da'awar: wannan sauƙaƙan nunin yana ba da fiye da bit 1 na bayanin hankali—wanda ya isa don siginar binary "mai kyau/marar kyau", amma yayi nisa da wadataccen fuskar ɗan adam. Wannan tsarin yana taimakawa kwatanta nau'ikan nunin hankali daban-daban da gaske.

Yanayin Ai da Ba Code ba: Mutum-mutumi na sabis a cikin titin asibiti yana amfani da panel ɗin LED na gaba. Tsoho: Bugun farin laushi (tsaka-tsaki/mai aiki).
