Operating Device Hierarchical Menu Navigation

The patent implements dynamic behavior where the system adapts its response based on the current menu context. When a main menu item is activated, the system dynamically determines whether to switch to the corresponding submenu or remain on the main menu based on predefined conditions (such as whether a submenu is actually available or appropriate). This dynamic adjustment resolves the contradiction by providing efficient automatic navigation when appropriate while preventing disorienting automatic switches when not appropriate.

The patent makes the operating elements universal by enabling them to perform multiple functions depending on the current menu context. The same operating element can activate a main menu item, automatically activate a submenu, or simply select an item without automatic submenu activation. This multi-functionality allows the system to maintain rich menu capabilities while minimizing the number of physical operating elements required, as each element adapts its function based on the current state rather than requiring separate elements for each function.
