Augmented reality (AR) is a very popular technology of the 21st century as it merges the virtual world into the real world and, in that way, one world enhances the other. Its use in everyday life further enhances the user experience of mobile applications we use. It is also very popular on various social networks where it has an entertaining role. Apart from being interesting and fun, a mobile application must be useful and functional, and that is where user experience design (UX) comes in. User experience design is a very interesting area involving research of a specific topic, and drawing conclusions useful in the making of application designs for various user interfaces. This thesis covers the topic of augmented reality and user experience design in theory, and explores ways to use augmented reality within mobile applications. The practical part includes going through the UX process needed for designing an android mobile application, making a prototype of the same mobile application and creating an AR experience appropriate for the topic of the application. The topic of this mobile application is making an appointment for a visit to the hair salon. Regarding the softwares used in the practical part, Figma was used to create the design of the mobile application, as well as a software for prototyping, a software for making 3D models and a software for creating the AR experience.
