Virtual Object Operation Control for Uncertain Sensor Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems lack a general-purpose means to control operations on uncertain objects using sensor information, as they require complex logic to differentiate between certain and uncertain object presence, making it difficult to integrate determination of operation feasibility into operation logic, especially in cloud architectures handling various operations.
Innovation Solution
An operation control device and method that utilize a virtual object setting unit to estimate an operation object's presence probability and operation-related attributes, allowing determination of feasible operations using a virtual object operation determination unit, enabling simplified control logic for uncertain objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional control methods are used for uncertain objects, then system complexity increases, but operation feasibility determination becomes difficult
Solution Approach 1:
The patent introduces a virtual object as an intermediary between sensor information and operation control. The virtual object serves as a mediator that bridges the gap between uncertain sensor data and definitive control decisions, allowing the system to handle uncertainty without complex control logic by performing operations on the virtual representation rather than directly on uncertain real-world objects
Solution Approach 2:
The patent creates a virtual copy of the real-world object based on sensor information. This virtual object copies the essential attributes and state of the real object, allowing the system to perform control operations on the copy with full certainty even when the real object's presence or state is uncertain, thereby simplifying the control logic while maintaining reliable operation feasibility determination
2Adaptability or versatility
If fuzzy logic is used to handle ambiguous sensor information, then control of uncertain objects becomes possible, but system designing becomes extremely difficult
Solution Approach 1:
The patent segments the control system into distinct modules: sensor information acquisition, virtual object generation, and operation control. By separating the handling of uncertain sensor data from the control logic through the virtual object intermediary, the system achieves adaptability for uncertain objects while keeping each module simple and manageable, avoiding the need for complex integrated fuzzy logic design
Solution Approach 2:
The virtual object acts as a mediator that decouples the uncertain sensor information from the control logic. This intermediary allows the system to adapt to various uncertain scenarios without requiring the control system itself to be complex, as the virtual object absorbs and manages the uncertainty while presenting definite control targets
3Measurement precision
If operation logic is modified to determine feasibility for uncertain objects, then control accuracy improves, but existing operation logic must be changed
Solution Approach 1:
The patent creates a virtual copy of the operation logic that operates on the virtual object instead of modifying the original operation logic. This copying approach allows precise feasibility determination for uncertain objects by evaluating operations on the virtual representation, while the original operation logic remains unchanged and can be reused as-is
Solution Approach 2:
The virtual object serves as an intermediary layer between the existing operation logic and uncertain sensor information. This mediator enables accurate feasibility determination by providing a definite target for existing operations without requiring modifications to the operation logic itself, as all adaptations are handled at the virtual object level

AI summary
An operation control device for controlling operation of an operation device with respect to an operation object includes: operation logic unit that stores in advance an operation logic related to sensor information; virtual object setting unit that sets an operation object to be estimated based on sensor information, as a virtual operation object having an attribute related to presence probability and an operation-related attribute; virtual object operation determination unit that determines whether it is possible to perform an operation with respect to the virtual operation object, based on the attribute related to a presence probability and the operation-related attribute; and operation control unit that controls an operation of the operation device with respect to the operation object by using an operation logic stored in the operation logic means, based on sensor information output from the sensor and a determination result by the virtual object operation determination unit.
