AI External Device Control Using Proximity and Situation Inference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an artificial intelligence device capable of controlling external devices without relying on a network connection or voice recognition service, particularly when the connection between the AI device and server is not established.
Innovation Solution
The AI device determines the proximity of external devices using a distance sensor and displays operation menu items on a display unit to control nearby devices, utilizing situation information and a device-to-be-used inference model to select the appropriate device for control, even when network connectivity is absent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice recognition service is used to control external devices, then device control capability is improved, but system reliability deteriorates when network connection is lost
Solution Approach 1:
The patent introduces a distance sensor as an intermediary to determine device proximity and establish control targets without requiring network connection or voice recognition service. The sensor acts as a mediator that enables device control capability through spatial information when traditional methods are unavailable.
Solution Approach 2:
The artificial intelligence device performs self-determination of control targets using its own distance sensing capabilities and situation information, rather than relying on external voice recognition services. The device serves itself by autonomously identifying which external device to control based on proximity detection.
2Reliability
If distance-based device selection is implemented, then system reliability is improved when network is unavailable, but device complexity increases
Solution Approach 1:
The patent segments the device control process into distinct phases: distance measurement phase, situation information acquisition phase, and device determination phase. This segmentation allows the system to use simple distance-based selection when needed while maintaining the option for more complex voice recognition methods when available.
Solution Approach 2:
The patent applies different control strategies based on local conditions: when the AI device is in close proximity to an external device, it uses simple distance-based selection; when farther away or when voice commands are provided, it uses situation information and voice recognition. This local quality approach optimizes reliability for nearby devices while maintaining versatility for remote control.
3Measurement precision
If situation information is acquired for device determination, then control accuracy is improved, but response time increases
Solution Approach 1:
The patent implements a dynamic decision-making process where the AI device adjusts its device selection strategy based on real-time conditions. When an external device is detected in close proximity, the system immediately uses distance-based selection for fast response. When no nearby devices are detected or voice commands are provided, the system dynamically switches to situation information analysis for higher accuracy, accepting the longer response time only when necessary.

AI summary
An artificial intelligence device for controlling an external device includes a display unit, and a processor configured to acquire a distance between the artificial intelligence device and a first external device, determine whether the acquired distance is less than a reference distance, display a first operation menu item for controlling the first external device on the display unit when the acquired distance is less than the reference distance, acquire situation information when the acquired distance is equal to or greater than the reference distance, determine a second external device as an object to be controlled based on the acquired situation information, and display a second operation menu item for controlling the determined second external device on the display unit.
