Povzetek

Članek predstavlja uporabniško študijo, ki primerja uspešnost in uporabnost različnih naprav za natančno manipulacijo s 3D objekti: običajno računalniško miško, 3D miško in vmesnik Leap Motion, ki temelji na uporabi kretenj. Pokazali smo, da je 3D miška zelo primerna za takšna opravila, saj so z njo uporabniki dosegli najmanjše napake v rotaciji, hkrati pa je dosegla najvišjo oceno za uporabniško izkušnjo. Uporabniki so izvedli opravila enako hitro kot z običajno miško. 3D miška je dosegla v povprečju oceno 88,7 na lestvici System Usability Scale (SUS), običajna miška je dosegla 72,4, vmesnik Leap Motion pa 56,5. Med rezultati študije se izkazalo, da uporabniki največ časa za naloge porabijo z uporabo vmesnika Leap Motion, in da se njegove uporabe niso priučili tako hitro kot uporabe 3D miške. Zaključek študije je, da je 3D miška trenutno najbolj primerna vhodna naprava med testiranimi za opravila v 3D okolju, ki potrebujejo tako natančnost, hitrost in se je njihove kot hitro učno krivuljo.
