UX/UI design of a music player application from the perspective of psychology and semiotics

The presented work deals with rules for designing user-friendly mobile applications and their practical utilization in creating a music playback application. The first part defines rules that stem from general human-computer interaction. The second part defines rules based on color psychology, behavioral psychology, and semiotics. Colors have a significant impact on the human psyche and can influence the mood and behavior of users. The work defines UX rules based on emotions and associations associated with specific colors. Behavioral psychology provides useful tools for designing interaction and user interfaces that enhance the user experience. Semiotics focuses on the meaning of symbols and signs in communication and can help create understandable and intuitive navigation in the application. The last part focuses on creating a prototype of the application using the design sprint method, in which the rules established in the theoretical part are utilized. The design of the application is subsequently tested with respondents. Through testing, we gather feedback on UX/UI principles, semiotic icons used in the prototype, and create a persona for whom the application can be implemented in the future. The respondents confirmed the simplicity and clarity of the prototype and suggested adjustments for better UX.
