Kei a rātou inaianei te kaha ki te whakarite whatunga mō ia kiritaki, mō ia taupānga rānei, he mea pai mō ngā tāone atamai me te IoT. Ka hoatu e ngā OLT mariko ki ngā tīma whatunga he mana whakahaere me te ngāwari ake.

Whakaurunga AI

He nui te hangarau mohio (AI) i roto i ngā taputapu OLT. Ka taea e te AI te kite i ngā raruraru i mua i te whakararuraru i ngā whatunga whatu. Ka taea e ia te āwhina ki te rapu raruraru me te whakatikatika i ngā whatunga whānui muka me te kore he āwhina a te tangata. Ko te tikanga o te tiaki matapae he iti ake ngā motuhanga, he mea nui ngā OLT whakahohea e te AI mō te whakahaere whatunga whai hua i te whanaketanga o ngā hiahia o ngā kaiwhakamahi.

Whakamutunga

Kei waenganui o ngā whatunga muka tere-teitei ngā OLT. Ka ārahi i te waka, ka pupuri i ngā hononga, ā, ka tautoko i ngā hangarau o muri mai. Mai i ngā pokapū tāone nui ki ngā hapori taiwhenua, ka taea e ngā OLT te hono tonu, te whai hua, me te whai wāhi. He tere ake, he pono ake hoki ngā hononga i roto i ia whanaketanga. Hei tauira, ka taea e te tari pukumahi te whakahaere waea ataata kore he raruraru, i te wā e taea ai e te whare te rere raupapa me te whai wāhi ki te petipeti i te wā kotahi. Ka āwhina ngā OLT ki te tiaki i ngā whatunga mai i ngā whakaeke kino. I te putanga mai o ngā taputapu hou, ka noho tonu ngā OLT. Kia mau tonu ai, ka taea e te tangata te pānui i ngā purongo hangarau, te kōrero ki ngā tohunga whatunga, te arotake rānei i ngā aratohu. Ka puta te whanaketanga pono i roto i ngā pikinga inihi, nō reira me haere tonu ki te uiui, ki te whakaako, me te mahi tahi me te hunga e ngākau nui ana ki ngā hononga pakari, haumaru.
