In the theoretical part of the paper, interaction design is explained as a concept, application and best practice in designing interactions between the user and the product being used and how it affects the user experience. The paper presents the principles and best practices of designing for quality user experience and interaction with computer devices, focusing on user interfaces of touchscreen devices. After the design, the paper deals with web technology as a popular way to develop applications and touches on modern tools and technologies as solutions for developing websites. It compares web applications with native mobile applications and presents the concept of progressive web applications. In the practical part, the work goes through the process of developing an interactive web application for a device with a large touchscreen display. The web application developed using the React library is an example of an infokiosk where multiple users can simultaneously discover content by interacting with different touch gestures. The paper shows the technologies and tools used, how the design of the user interface was implemented, and the development and implementation of touch gestures as a way for user interaction by manipulating elements in the user interface.
