Beacon Receiver Screen Switching for Shared Image Formers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared user environments, existing image forming apparatuses often inadvertently switch the operating environment when a second user approaches, disrupting the first user's operation.
Innovation Solution
An image forming apparatus that includes a beacon receiver to identify nearby users and switches the display to a customized individual standby screen only for the closest user, preventing disruption of the first user's operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device switches the using environment when a user carrying identification information comes close, then the screen can be customized for the close user, but the operation of other users is disturbed
Solution Approach 1:
The system dynamically adjusts screen display behavior based on the operational state. When the first user is actively operating the device, the system maintains the current screen regardless of second user proximity. When no user is operating, the system dynamically switches to display customized screens for approaching users. This dynamic state-based control resolves the contradiction between customization and operation continuity.
Solution Approach 2:
The system changes the parameter of screen display priority based on operational context. During active operation, the priority parameter favors operation continuity (suppressing screen switches). During standby state, the priority parameter favors user customization (allowing screen switches). This parameter change approach enables the system to satisfy both contradictory requirements under different conditions.
2Adaptability or versatility
If the screen is switched to individual standby screen for each user, then user-specific customization is achieved, but the system complexity increases
Solution Approach 1:
The system performs preliminary preparation by storing multiple individual standby screens in advance, each associated with specific user identification information. When a user approaches, the system simply retrieves the pre-prepared screen rather than generating it dynamically. This preliminary action reduces the complexity of real-time screen management while maintaining high adaptability.
Solution Approach 2:
The system creates simplified copies of user-specific interfaces through individual standby screens. Each standby screen is a simplified version tailored to specific user needs, containing only relevant screen transition objects. This copying approach enables customization without requiring complex real-time adaptation logic.

AI summary
An image forming apparatus includes: an image forming device forming an image; an input device; a beacon receiver; a storage storing definition information for defining a common standby screen, an individual standby screen and a transition destination screen; a display configured to display screens defined by the definition information; and a controller. The controller executes: display control processing of displaying the standby screen and the standby screen on the display when the input device is not operated for a time period; storage control processing of, when receiving the beacon signal, storing beacon information; reception processing of receiving a user's operation of selecting the screen transition object; screen transition processing of, when the operation is received, displaying the transition destination screen; and switching processing of displaying the individual standby screen associated with target identification information only when the standby screen is displayed.
