Touchscreen Progress Bar for Vehicular Function Selection

The progress bar is enhanced to serve multiple functions: it displays travel progress overview while simultaneously enabling users to select specific points in time or waypoints. By making the progress bar interactive and clickable at any position, it becomes a universal interface element that combines information display with function selection capability, resolving the contradiction between providing overview and enabling adaptive function execution.

The patent merges the progress bar display with the time selection function into a single integrated interface. Instead of using separate elements like slider buttons that require additional space and操作步骤, the progress bar itself becomes the selection mechanism. Users can click at any position on the progress bar to select precise time points while the entire progress bar remains visible, providing both quick overview and precise selection in one element.

The progress bar is designed as a universal control element that can trigger different navigation functions based on the selected position and context. Whether for displaying map sections, weather information, or media playback, the same progress bar interface serves all these functions. This multi-functionality reduces the number of separate controls needed while maintaining precise function execution through position-based selection.
