Situation Awareness System Using Voice Response and Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing situation awareness systems that use cameras to monitor target persons can make the target persons feel uncomfortable or burdened by the constant surveillance.
Innovation Solution
A situation awareness system that employs detection sensors to gather information about the target person and their environment, and a voice response device to interact with the target person, allowing the system to grasp the situation without using cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a camera is used to monitor the target person, then the system can grasp the situation of the target person, but the target person may feel resistance or burden due to constant surveillance
Solution Approach 1:
The patent extracts the monitoring function from visual cameras and transfers it to non-visual detection sensors (microphone, sensors). This removes the harmful visual surveillance element while preserving the situation grasp capability through alternative means such as voice recognition and sensor data.
Solution Approach 2:
The patent replaces the mechanical/optical camera system with acoustic and electronic detection systems (microphone, voice recognition, sensors). This substitution eliminates the visual monitoring burden while maintaining situation awareness through voice and environmental sensor data.
2Object-affected harmful factors
If detection sensors and voice response devices are used instead of cameras, then the target person's comfort is improved, but the system must rely on non-visual detection methods which may have limitations
Solution Approach 1:
The patent implements a multi-functional detection system where the microphone and sensors serve multiple purposes: voice recognition, environmental monitoring, situation detection, and trigger generation for voice response. This multi-functionality compensates for the limitations of non-visual detection by integrating various detection modalities.
Solution Approach 2:
The system employs feedback through voice response devices that communicate detected situations back to the target person. This closed-loop feedback mechanism enhances situation awareness by providing verbal confirmation and interaction, compensating for the lack of visual feedback that cameras would provide.

AI summary
A situation awareness system that is configured to grasp a situation of a target person in a residence, includes one or more detection sensors configured to perform at least any one of detecting the target person, detecting a state of an installation object which is installed in the residence and of which the state is changeable due to an operation of the target person, and detecting a state of an environment in the residence, a voice response device configured to perform a voice response including an utterance to the target person, and a storage section configured to store information. The voice response device is configured to perform an utterance to the target person with a content in accordance with a result of the detection by the detection sensor, and store information including a conversation content with the target person accompanying the utterance in the storage section.
