This design organizes complex functions into a clear visual structure, allowing users to control the full massage experience with ease. Low-frequency, body-specific controls are grouped in the lower section and hidden with a sliding cover. The upper area presents only the display and essential buttons for a clean layout, while detailed functions appear only when the cover is opened. This dual-layer structure is especially effective for feature-dense massage-chair remotes, offering a UX that reveals complexity only when needed. Based on the principle that devices with many functions should appear simpler, the design provides a selectively expandable remote experience that stays minimal until the moment of use.
