Imaging GUI Timeout Feedback for State Sync Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inconsistency between the display state on graphical user interfaces (GUIs) and the control state of imaging devices occurs due to temporary unavailability of functions or external factors, such as attached lenses, leading to inconsistent user interactions.
Innovation Solution
A display control device that adjusts GUI states based on user operations, transmits control commands, and re-displays GUIs after a predetermined standby time if no state change is received from the imaging device, with adjustable standby times for different functions and lens characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application transmits control commands to the imaging device and waits for state change notifications, then the display state on GUIs can be updated in response to actual device state changes, but inconsistency may occur between the display state and control state when the imaging device temporarily cannot respond due to function combinations or external factors
Solution Approach 1:
The system implements a feedback mechanism by transmitting control commands to the imaging device and waiting for state change notifications. The GUI display state is updated based on these notifications, creating a closed-loop feedback system that maintains consistency between the control state and display state.
Solution Approach 2:
The system performs a preliminary action by setting a timeout period after transmitting a control command. If no state change notification is received within this predetermined time, the system proactively determines that inconsistency has occurred and resets the GUI display state, preventing prolonged inconsistency.
2Use of energy by moving object
If the system waits for state change notifications from the imaging device before updating GUIs, then power consumption can be reduced by updating only when necessary, but the user interface may not reflect the current state in a timely manner when the device is unresponsive
Solution Approach 1:
The system uses feedback-based updates by waiting for state change notifications from the imaging device before updating the GUIs. This approach minimizes unnecessary updates and reduces power consumption while maintaining interface accuracy when the device is responsive.
Solution Approach 2:
The system performs a preliminary timeout check to determine whether the imaging device is unresponsive. If no notification is received within the predetermined time, the system proactively resets the GUI display state, ensuring the interface remains responsive and accurate even when the device fails to notify.
3Reliability
If the application continuously polls the imaging device for state monitoring, then the consistency between display state and control state can be maintained, but communication load and power consumption increase
Solution Approach 1:
The system adopts an event-driven feedback approach where the imaging device notifies the application of state changes. This eliminates the need for continuous polling, reducing communication load and power consumption while maintaining reliability through notification-based state synchronization.
Solution Approach 2:
The system performs a preliminary timeout-based check to detect device unresponsiveness without continuous polling. By setting a predetermined time threshold and checking whether notifications are received within this window, the system maintains reliability with minimal communication overhead.

AI summary
In order to bring a display state of a GUI for controlling an imaging device into an appropriate state, a display control device includes at least one processor configured to cause graphical user interfaces (GUIs) for controlling the imaging device to be displayed on a display device; transmit a control command to the imaging device via a communication interface in response to an operation input from a user via the GUIs; and change a display state of a part of the GUIs in a case where change information indicating a predetermined state change is not received from the imaging device even after a predetermined standby time elapses from transmission of the control command to the imaging device.
