The UX design process of the "Nine Views" application includes user preference research, prototype design and interface testing and optimization. Emphasis is placed on the usability, accessibility and attractiveness of applications, with the aim of achieving a positive user experience. The application offers a number of functionalities, including a virtual exploration of the solar system, educational content, a children's corner with creative activities and the ability to follow astronomical events. The key challenge was to harmonize the aesthetic and functional aspects of the interface to allow users to easily navigate and interact with the application. Through the use of color, icons, typography and 3D models of the planets, they are visually brought to life, and the application additionally motivates users to explore the real locations of the planets in Zagreb. Children can color the planets according to their own taste, which encourages the creativity and engagement of the younger population.
