SecretoTools is developed as a practical software project, with decisions tested against real television devices and real user needs. This article documents the principles behind that work.
Focus must always be visible
A TV interface should never leave the user wondering which element is selected. Strong focus states, spacing and motion cues make navigation understandable from across the room.
Directional movement should feel logical
Users build a mental map of the screen. Focus order should follow visual structure and avoid unexpected jumps between distant controls.
Design for distance
Text size, contrast and concise labels matter more on a television. Information density must be controlled so that the interface remains calm and readable.
