The subject of this paper is the development and design solution of an augmented reality application for marketing purposes. The main goal of the study is to examine the functionality of Unity software and Vuforia software development kit, as well as create an application that will allow the user to play video content using augmented reality technology. The application's primary goal is to give the user more information about the Company behind the Augmented Reality target image. The development of the application was preceded by research in the field of immersive technologies and software for Augmented Reality development. The aim of this research is to set up an intuitive system in the form of a mobile application that would identify the image and play and control the video content on the mobile device screen using Augmented Reality technology.

This paper focuses on the influence of colour on customers’ trust in websites in the fields of online banking and cryptocurrency trading. The literature reviews associated with the use of colour in web design shows that colour has a significant influence on customers’ interaction with websites. Considering that, this study aimed to determine the relationship between used colour and trust towards websites in the specific areas of online banking and cryptocurrency trading. The method used to explore these relationships was an online survey, based on Likert scale. The survey inquired data about respondents, such as gender, age, level of education and their use of online banking and cryptocurrency trading. The main part of the survey was the one where the respondents were presented with website stimuli that differed in colour, and evaluated through grades on the Likert scale on given statements related to trust. To define to which extent, the chosen colour palette along with some users’ general characteristics impacts the perception toward trust of presented websites, Kruskal–Wallis one-way analysis of variance and Mann–Whitney U test was conducted. The results indicated that there is a difference in respondents’ trust towards websites in the fields of online banking and cryptocurrency trading depending on the colour used as the dominant in website design. Statistical significance was partly reached to their age and gender but not to their level of education. Overall, the study showed that when designing websites in the fields of online banking and cryptocurrency trading, choosing colour palettes that are needed to be trustworthy to the targeted audience is the issue that should be addressed with attention.

Tema ovog rada jeste ispitivanje utica­ja boje na poverenje korisnika kada su u pitanju veb saj­tovi u oblasti elektronskog bankarstva. Literatura koja se bavi upotrebom boje u veb dizajnu pokazuje da boja ima značajan uticaj na interakciju kupaca sa veb sajtovima. S obzirom da je boja najvažnija karakteristika veb sajtova, cilj ove studije bio je da se utvrdi odnos između njih u ob­lasti elektronskog bankarstva. Metoda korišćena za istra­živanje ovih odnosa bila je anketa, zasnovana na Liker­tovoj skali.

Chromatic aberration is an optical defect that causes light rays of different wavelengths to focus at different points along the optical axis of the lens. It is manifested as band of one color at frame transitions around contrasting edges in the photo. There are two types of chromatic aberration: longitudinal and lateral. Lateral chromatic aberration is the color fringing that occurs because the magnification of the image differs with wavelength. It tends to be far more visible than longitudinal. The aim of this research is to examine the influence of depth of field on the appearance of lateral chromatic aberration. For the purposes of the experiment, we used one mirrorless camera (Sony a1), while the lenses were variable. We used Sigma 85mm f/1.4 DG DN and Sigma 40mm f/1.4 to check which type of lens shows the most chromatic aberration and how much the change in f-number affects its appearance.
