High-quality User Interface
“The current user interface (UI) has two major roles: displaying fixed information that does not change, like a power switch, and displaying information that changes depending on the situation.
A high-quality UI is considered to be one that combines both roles in a balanced manner to achieve comfortable information display.
In recent years, even home appliance companies have been reducing the number of physical buttons and integrating some operations into LCD panels to accommodate increasingly multifunctional products.
Products that control IoT devices, like smart speakers, have received high ratings not only for their UI, but also for their design based on user experience (UX) gained through product use.”
