Redesign rezervačního systému pro sportovce

This master's thesis focuses on a comprehensive user interface redesign of a booking system intended for sports organizations, while the design process is anchored in the Design Thinking methodology and Human-Computer Interaction principles. The objective of the work was to transform the original, functionally limited platform into an intuitive tool that effectively handles the needs of coaches, athletes, and especially parents managing their children's activities. In the analytical part, the author identified critical pain points of the existing solution, primarily high cognitive load and identity fragmentation, which forced users to repeatedly switch profiles. The practical output is a validated high-fidelity prototype, which introduces an innovative model of aggregated sub-profiles and static navigation ensuring constant orientation within the system. The design also reflects the specifics of the SportsHCI field, as it optimizes administrative flows so that they do not distract from the sporting activity itself. The success of the redesign was verified through user testing, in which the system achieved an excellent rating on the System Usability Scale (SUS), 83.75 points for administrators and 87.50 points for clients. The thesis further critically analyzes the use of modern AI tools in the design process and serves as a robust basis for subsequent technical implementation by a development team.
