Application of VR systems for assessing perceived product quality

Tehnologija virtualne stvarnosti (VS) u području konstruiranja upotrebljava se posljednjih nekoliko desetljeća. Napretkom tehnologije, došlo je do razvoja VS sustava čiji se zasloni nose na glavi korisnika (eng. Head-mounted display, HMD). Takve sustave karakterizira pristupačna cijena i mali prostorni zahtjevi, zbog čega su postali dostupni većem broju korisnika. S većom raširenošću VS tehnologija, pronalaze se i nove primjene u procesu razvoja proizvoda. Kao jedna od njih, nameće se i procjena percipirane kvalitete (PK) proizvoda, gdje je ipak još uvijek slabo zastupljena. Ovaj rad uključuje pregled literature na temu PK-a i VS tehnologije s ciljem osmišljavanja eksperimenta kao i opis samog eksperimenta kojim se uspoređuju dva načina prikaza za procjenu PK-a: tradicionalno korišteni prikaz fotografija na zaslonu računala i prikaz pomoću VS sustava. VS sustav je uz svoju jednostavnost korištenja pridonio kvalitetnijoj procjeni, no ipak pokazao je i neke svoje nedostatke poput mutnog prikaza.Virtual reality technologies have been used in a product design for several decades. Due to technology development, a new generation of hardware, with devices that are worn on the user's head (Head-mounted display, HMD), has emerged. Because of a much lower cost and space requirements of HMD devices, VR technologies have become accessible to a wider range of users. With the increasing prevalence of VS technologies, new applications are being found in the product development process. One of them is the assessment of the perceived quality of products, where it is still poorly represented. This paper includes a review of the literature on perceived quality and virtual reality technology with the aim of designing an experiment as well as a description of the experiment itself. The experiment compares two display modes for perceived quality assessment: traditionally used display of photos on a computer screen and display using a virtual reality system. In addition to its ease of use, the VS system has contributed to a better assessment, but it has also shown some of its disadvantages, such as a blurry display
