Abstract

U ovom radu istražuje se koncept virtualne stvarnosti (VR) s naglaskom na interaktivnost između modela, korisnika i okoline kao ključni element korisničkog iskustva. Nakon pregleda relevantnih tehnologija i njihovih primjena, predložena je metodologija izrade interaktivnog virtualnog okruženja koja potencijalnim korisnicima omogućava dublje razumijevanje VR tehnologija i sustava, kao i njihovih mogućnosti pri kreaciji interaktivne virtualne stvarnosti. Također je opisan detaljan postupak izrade virtualnog okruženja kako bi se minimizirali problemi na koje se nailazi pri kreiranju interaktivnih iskustava. Kroz četri praktična primjera prikazane su mogućnosti interaktivnosti u virtualnoj stvarnosti korištenjem alata SimLab VR Studio, te je za svaki primjer razložen detaljan opis koji vodi korisnika kroz korake izrade, čime se osigurava jasno razumijevanje i pravilno korištenje alata. Prvo je prikazan primjer prilagodbe prostorije, gdje korisnik sam odabire izgled i raspored elemenata prema vlastitim željama. Zatim su prikazani različiti virtualni efekti koji stvaraju uvjerljivu percepciju realnosti virtualnog okruženja, pri čemu kombinacija više efekata omogućuje stvaranje dojmljivog virtualnog iskustva. Na sljedećem primjeru prikazan je proces rastavljanja i sastavljanja miksera, gdje korisnik prolazi kroz različite faze rastavljanja uređaja, pritom koristeći alate unutar virtualne stvarnosti, i dobiva uvid u njegovu unutarnju strukturu i način na koji funkcionira. Na kraju su izrađene simulacije rada reduktora i zavarivanja autonomne robotske ruke, koje služe za analizu i preispitivanje ispravnosti modela. Rad pruža uvid u suvremene VR tehnologije i potencijal virtualne stvarnosti u kontekstu konstruiranja, oblikovanja, edukacije korisnika i primjeni u različitim fazama razvoja proizvoda, pritom naglašavajući važnost interaktivnosti pri stvaranju uvjerljivog virtualnog iskustva.

Abstract (english)

This presented work explores the concept of virtual reality (VR) with an emphasis on the interactivity between the model, the user and the environment as a key element of the user experience. After reviewing the relevant technologies and their applications, the methodology for creating interactive virtual environment is described. The methodology is described in a way that enables potential users to gain deeper understanding of VR systems and their capabilities for creating interactive virtual environments. Hence, a detailed process of creating a virtual environment is described in order to minimize problems that are often encountered when creating an interactive experience. Through four practical examples, the possibilities of creating interactivity in VR while using a software tool SimLab VR Studio are shown. For each example a detailed description is provided that guides the user through the steps of creation, thus ensuring a clear understanding and proper use of tools. Firstly, an example of room customization is presented, where the user chooses the appearance and arrangement of elements according to their own preferences. Then, various virtual effects are shown that create realistic perception of the virtual environment, whereby the combination of several effects enables the creation of an impressive virtual experience. The next example shows the process of disassembling and assembling of a mixer, where the user goes through different stages of disassembling the device, while using tools within VR, and gets an insight into its internal structure and working principles. At the end, simulations of the operation of the reducer and welding of the autonomous robotic arm were made, which are used to analyze and review the correctness of the model. The presented work provides an insight into contemporary VR technologies and the potential of VR in the context of design, user education and application in different stages of product development, while emphasizing the importance of interactivity in creating a convincing virtual experience.
