Abstract

The development of web technologies has led to the availability of various multimedia content on the web. In addition to text, images, and videos, transitions, animations and interactivity are increasingly used. Transitions and animations present the content on the page in more interesting, attractive ways and can attract and retain users longer, improving the measurable parameters of page visits as well as the user experience. Animations on the web can be created in many ways. And if the animations are not executed well, they can slow down the page. The goal of this article is to compare the measurable parameters of animations created with different technologies. HTML, CSS, SVG, P5js, WebGL technologies and animations created with a 3D modeling tool were used. The article uses two different examples of animations created with different technologies and then tested on several devices.

Abstract

This paper proposes a method for changing pixel shape by converting a CMYK raster image (pixel) to an HSB vector image, replacing the square cells of the CMYK pixels with different vector shapes. The replacement of a pixel by the selected vector shape is done depending on the detected color values for each pixel. The CMYK values are first converted to the corresponding RGB values and then to the HSB system, and the vector shape is selected based on the obtained hue values. The vector shape is drawn in the defined space, according to the row and column matrix of the pixels of the original CMYK image. Twenty-one vector shapes are introduced to replace the pixels depending on the hue. The pixels of each hue are replaced by a different shape. The application of this conversion has its greatest value in the creation of security graphics for printed documents and the individualization of digital artwork by creating structured patterns based on the hue.

Abstract

Internet users are bombarded every day with various ads, and they try to block them in all possible ways. If they do not block them, they usually pay little attention to them. Therefore, ads need to be creative and provide as much relevant information as possible about the advertised product or service at a glance in order to lead to conversions. For this purpose, the benefits of infographics can be used very well, in addition to dynamic forms of ads that consist of audio and video elements, especially in a responsive web environment. This type of advertising is also great for posting on social media, where the flow of information and responses is very fast. Infographics actually represent a visual presentation of information through a combination of typography, symbols, pictograms, shapes, and colours and are used to present complex information quickly and clearly. The use of infographics as one of the multimedia elements in digital advertising contributes to the optimization of advertising content, which also contributes to SEO optimization. To investigate the extent to which infographics in digital advertising can contribute to the optimization of advertising content in a responsive web environment, A/B testing of multimedia advertising content presented through infographics and content that contained all relevant information about the advertiser and was not presented in the form of an infographic was conducted on two types of screens. The A/B testing model itself provides the opportunity to maximize conversion rates, but it also provides a significant increase in knowledge about how advertising content is presented. It can also establish a set of optimized practices for multimedia elements of ad content. The proposed testing model provides the perfect opportunity to properly test your ad before launch. The same analogy can be applied to other multimedia elements used to create ads, such as photos, animations, colours, content management system elements, etc. The obtained results provide valuable information about infographics possibilities in advertising content optimization in a responsive web environment because they load faster, are suitable for small screens, and do not tire users.
