Zvita 8 – Vaongorori vanobva kuYunivhesiti yeCalifornia, Santa Barbara (UC Santa Barbara) vakaratidza tekinoroji itsva yekuratidza muongororo yakabudiswa mujenari reScience Robotics: mifananidzo inochinja-chinja yainopa haingooneki chete asiwo inoonekwa nemuviri. Chidzidzo ichi chinopa nzvimbo yakatetepa ye optoelectronic haptic yakafukidzwa nema pixels e millimeter-scale; kana ikavhenekerwa nechiedza chipfupi, ma pixels aya anoputika kuita mabumps anogona kunzwiwa nekubata.
Chirongwa ichi chakatanga muna 2021 kubva pamubvunzo uri nyore wakabvunzwa naProfessor Yon Visell weUC Santa Barbara: Chiedza chinoshandiswa kugadzira mifananidzo chinogonawo kugadzira mhinduro yemuchina yakasimba zvekuti inoonekwa nemaoko evanhu here? Mushure megore rekugadzira modhi uye kuyedza kakawanda kwakundikana, Max Linnander, muongorori wepayunivhesiti, akabudirira kugadzira mudziyo wekutanga wekusimbisa pfungwa pakupera kwa2022. Ichingoshandiswa chete nekupenya kwechiedza kubva ku diode laser diki uye isina zvikamu zvemagetsi zvakaiswa mukati, mudziyo uyu unogona kugadzira ma pulses akajeka, anoonekwa kana akabatwa.

Zvinonzwisisika kuti dhizaini yakazara yekuratidzwa inotsanangurwa muchidzidzo ichi yakavakirwa pakubudirira uku. Pikseli yega yega ine firimu repamusoro rakatetepa, gomba diki remhepo riri pasi payo, uye firimu regirafiti rakarembera. Kana ikaiswa pachiedza, firimu regirafiti rinotora simba rechiedza uye rinochichinja nekukurumidza kuita kupisa, zvichiita kuti mhepo iri pasi pefirimu ikure uye isundire pamusoro kumusoro kusvika pamirimita imwe chete. Kukura uku kwekuchinja kwakakwana kuti vashandisi vakwanise kuwana mapikiseli ega ega neminwe yavo.
Sezvo daya relaser rimwe chete richipa simba uye kero ye pixel, panel yese haidi waya yemukati. Sisitimu yekuskena inokurumidza inogona kukurumidza kupararira mu pixel array, ichivhura ma pixel rimwe nerimwe kuti igadzire ma animations anooneka uye anobatika.
Chikwata chekutsvagisa parizvino chakabudirira kugadzira array ine mapikiseli anopfuura 1,500 anogona kugadziriswa ari ega, budiriro huru kana tichienzanisa ne haptic displays dzakambotadza kuenzana ne pixel density, response speed, uye displacement amplitude. Nguva yayo yekupindura inotangira pa 2 kusvika 100 milliseconds, yakakwana kubereka contours dzakatsetseka, maumbirwo, uye hunhu. Mumiedzo yevashandisi, vatori vechikamu vakakwanisa kunyatso tevera zvinofamba, kusiyanisa marongerwo enzvimbo, uye kuona ruzivo rwenguva rwunoumbwa ne sequential activation yemapikiseli.
Vaongorori vanoti nekuda kwechirongwa chekutarisa maateri, tekinoroji iyi inopa mukana wekukura zvakanaka. Ma arrays makuru anogona kushandiswa nema compact scanning lasers anoshandiswa muma projector emazuva ano. Vanofungidzirawo mashandisirwo akasiyana-siyana, akadai se automotive human-machine interfaces anotevedzera physical controls, uye electronic texts kana diagrams dzinochinja chimiro pasi pechanza chemuverengi.
Kunyangwe ichiri muchikamu chemuenzaniso, chidzidzo ichi chinoratidza kekutanga simba rechiedza richishandurwa zvakananga kuita shanduko yemakanika ine resolution yepamusoro. Saka timu yeUC Santa Barbara yakagadzira nzira itsva: ma haptic displays emangwana achaita sema "visual displays" echinyakare, achipa ruzivo muchimiro chinogona kutariswa nemaziso panguva imwe chete uye kuongororwa neminwe.
