Display Control Device for Accurate User Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems often perform operations against the user's intention due to misinterpretation of selection motions, leading to unintended system actions.
Innovation Solution
A display control device that uses processing circuitry to project display objects in specific areas, detects user selections via sensors, and confirms selections by displaying secondary objects in different areas, ensuring that only intended actions are executed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a selection motion is detected by a sensor, then the system can respond to user input, but the system may perform operations against the user's intention due to misinterpretation of the selection motion
Solution Approach 1:
The system displays a candidate selection result based on the detected selection motion, then waits for confirmation or cancellation input from the user. This feedback loop allows the system to verify its interpretation of the user's intention before executing the operation, thereby preventing incorrect actions while maintaining responsive operation.
Solution Approach 2:
Before executing the final operation, the system performs a preliminary action by displaying the candidate selection result to the user. This preliminary display serves as a verification step that allows the user to confirm or cancel the intended operation, ensuring that the system acts only on verified user intentions.
2Adaptability or versatility
If the system displays multiple display objects and detects selection motions, then it can provide guiding information, but it cannot distinguish between intended and unintended selections
Solution Approach 1:
The system provides visual feedback by displaying the candidate selection result on the projection display device. This feedback mechanism allows the user to verify whether the system has correctly identified their intended selection, enabling them to confirm or cancel the operation before it is executed.
Solution Approach 2:
The candidate selection result display acts as an intermediary between the selection motion detection and the final operation execution. It mediates the interaction by presenting the system's interpretation to the user for verification, thereby bridging the gap between motion detection and accurate intention recognition.
3Productivity
If the system executes operations immediately upon detecting a selection motion, then it operates efficiently, but it may execute wrong operations due to misinterpretation
Solution Approach 1:
The system performs a preliminary action by displaying the candidate selection result before executing the final operation. This preliminary step adds minimal time to the operation flow but ensures that the system executes only verified user intentions, thereby maintaining high productivity while improving operation accuracy.
Solution Approach 2:
The system uses feedback by waiting for user confirmation or cancellation after displaying the candidate selection result. This feedback mechanism ensures that operations are executed only when the user's intention is verified, preventing wrong operations while maintaining efficient system response.

AI summary
A display control device includes: processing circuitry that sets a display content projected by a projector in such a manner that a first display object is displayed in a first display area; and that receives a signal detected by a detection sensor from the detection sensor and determines whether or not the first display object is selected by a user. The processing circuitry sets another display content projected by the projector in such a manner that a second display object corresponding to the first display object is displayed in a second display area different from the first display area in a case where it is determined that the first display object is selected, and determines whether or not the second display object is selected, and settles the determination that the first display object is selected in a case where the processing circuitry determines that the second display object is selected.
