Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home robot CCTVs struggle to accurately assess situations based on voice commands, leading to delayed responses in emergency situations due to the need for prediction and interpretation of complex scenarios.
Innovation Solution
A method for controlling intelligent security devices that captures video, recognizes pre-defined wake-up words, and sends commands to smart devices for operation, enabling video projection and real-time information dissemination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If voice-only communication is used in home robot CCTVs, then the device complexity is reduced, but the measurement precision of situation assessment deteriorates
Solution Approach 1:
The patent combines voice recognition with video projection technology, merging auditory and visual information channels. The smart device receives voice commands and projects relevant video content to help the user visually assess the situation, thereby improving measurement precision without significantly increasing device complexity
Solution Approach 2:
The patent introduces a smart device as an intermediary between the CCTV system and the user. This mediator receives voice commands, processes them with AI, and provides visual feedback through video projection, enabling accurate situation assessment while keeping the CCTV device itself relatively simple
2Measurement precision
If complex situation prediction is required based on voice, then the measurement precision of situation understanding is improved, but the loss of time increases
Solution Approach 1:
The patent implements preliminary action by having the smart device continuously monitor and analyze voice patterns, and by pre-processing video content for rapid projection. When a wake-up word is detected, the system immediately projects relevant video segments without requiring complex real-time analysis, thus reducing response time while maintaining understanding accuracy
Solution Approach 2:
The patent uses video projection to create a visual copy of the situation being monitored. Instead of requiring the user to mentally construct the situation from voice descriptions, the system projects actual video footage, providing immediate visual confirmation that reduces both analysis time and response time
3Loss of information
If video projection function is added to intelligent security device, then the information delivery capability is improved, but the device complexity increases
Solution Approach 1:
The patent uses a smart device as an intermediary to handle video projection functionality. The CCTV system captures video and sends it to the smart device, which then projects the video content. This approach improves information delivery capability while avoiding the need to integrate complex projection hardware directly into the security device
4Measurement precision
If AI processing is performed remotely on smart device, then the measurement precision of command generation is improved, but the loss of time in local processing is reduced
Solution Approach 1:
The patent implements preliminary action by pre-training AI models on the smart device and preparing processing pipelines in advance. When voice commands are received, the pre-configured AI system can immediately process the input and generate commands without requiring time-consuming model training or setup, thus reducing processing time while maintaining high accuracy
Data Source
AI summary
A method of controlling an intelligent security device can include capturing a video; collecting voice information included in the video; in response to determining that the voice information includes a wake-up word corresponding to a predetermined basic wake-up word for the intelligent security device, transmitting a spoken utterance included in the voice information to a smart device; receiving a command from the smart device, the command being generated based on information related to the spoken utterance; and executing an operation of the intelligent security device based on the command.
