Presence Area Control Using Coordinate and Distance Validation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for estimating positional relations between devices are affected by multi-path environments, leading to inaccurate control operations due to inconsistencies between coordinate-based and distance-based presence areas.
Innovation Solution
A control device and storage medium that determine a presence area based on signals transmitted and received between communication devices, performing control operations only when the presence area determined by coordinate position is consistent with the area determined by distance, thereby enhancing accuracy by using a control unit to align operations with the second presence area in case of inconsistencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position estimation is performed using signal transmission and reception between devices, then positional relation estimation capability is enabled, but estimation accuracy deteriorates in multi-path environments
Solution Approach 1:
The patent introduces a control device as an intermediary that receives position estimation results from the first communication device and validates them against presence area information from the second communication device. This intermediary layer filters out erroneous estimations caused by multi-path effects by comparing coordinate-based position data with distance-based presence area data, thereby improving overall measurement precision without requiring changes to the underlying signal transmission system.
Solution Approach 2:
The control device implements a feedback mechanism where the second presence area information (distance-based) is used to validate and correct the first position estimation result (coordinate-based). When inconsistencies are detected between the estimated position and the presence area, the control device adjusts or rejects the position estimation, creating a closed-loop system that continuously improves accuracy by feeding back validation results to correct estimation errors.
2Adaptability or versatility
If control operations are performed based on coordinate position in arbitrary coordinate system, then flexibility in position representation is improved, but consistency with distance-based presence area deteriorates
Solution Approach 1:
Instead of converting the distance-based presence area information into coordinate system format to match the position estimation, the patent inverts the approach by validating the coordinate-based position estimation against the distance-based presence area criteria. This inversion maintains the flexibility of using arbitrary coordinate systems while ensuring reliability by checking consistency with physical distance measurements through the control device's validation logic.
Solution Approach 2:
The control device dynamically adjusts the interpretation and usage of position parameters based on consistency checks. When the coordinate position falls within the validated presence area, the system uses the flexible coordinate-based control operations; when inconsistencies are detected, the system adjusts by rejecting or correcting the position parameter, thereby maintaining both adaptability and reliability through parameter validation and conditional usage.

AI summary
To provide a novel and improved control device and storage medium capable of performing control based on a positional relation with higher accuracy.A control device includes a control unit configured to perform control based on a presence area of a first communication device determined using a signal transmitted and received between the first communication device and at least one second communication device. The control unit performs control related to an operation of a controlled device in accordance with a second presence area when a first presence area determined based on a coordinate position of the first communication device on an arbitrary coordinate system associating the first communication device with the second communication device is inconsistent with the second presence area determined based on a distance between the first and second communication devices.
