I designed Linea for the moment you miss a line and want it again from the first word. Its seek wheel has one notch for every spoken line, making speech the unit of navigation. Repeat replays the current line, Next starts the following line, and Step pauses after each line until you continue. The caption window highlights the current word, connecting navigation with what you hear and read. I carried the wheel’s mechanical character through black glass, machined aluminium and one ember light, giving the player the form of a physical instrument. Keyboard control, 44 px targets and an upright phone layout support the same actions across inputs and screens.
