Multidirectional Display Operating Face Configuration

The patent divides the image display face into distinct regions with different functional properties. The operating face is configured to accept contact operations while the non-operating face does not, creating local quality differentiation. This is achieved by the configuration unit that specifies which face should be the operating face based on user position detection, thereby enabling touch operations only in the appropriate region to reduce power consumption and prevent accidental operations.

The patent implements dynamic configuration of the operating face based on real-time detection of user position. The specifying unit continuously monitors where the user is located relative to the device, and the configuration unit dynamically adjusts which face serves as the operating face. This dynamic adaptation allows the system to respond to different usage scenarios (e.g., user approaching from front vs. back) without requiring complex manual reconfiguration, thereby achieving both adaptability and reasonable system simplicity.

The patent applies local quality by enabling contact operation acceptance only in the operating face region while disabling it in the non-operating face region. This spatial differentiation of functional properties prevents accidental operations on the non-operating face while maintaining full operability on the operating face, thus resolving the contradiction between operational accessibility and prevention of harmful accidental operations.
