Absztrakt

A szociális robotok térnyerésével az emberekkel folytatott interakciók gördülékenyebbé tétele kulcsfontosságúvá válik. Az emberi kommunikáció fontos aspektusa az érzelmek, mint belső állapotok viselkedésben megjelenő kifejezése, melyek felismerése, és mesterségesen generált, helyzetnek megfelelő érzelemkifejezések mutatása a robotok számára is nagy jelentőséggel bír. Az emberi érzelmek kutatása, definiálása és modellezése a pszichológia, etológia és más kapcsolódó diszciplínák területéről kilépve a robotikával fonódik össze. Jelen cikkünkben az ember-robot interakciós kutatásokban használt elterjedt érzelemfelismerési és -kifejezési módszereket, illetve ezek szakirodalmi hátterét foglaljuk össze.
