Wearable Audio Processing for Real-Time Name Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wearable devices for lifelogging are limited in their ability to provide real-time feedback and advanced functionality, such as navigation and object/person identification, due to their size and design, and lack efficient processing of captured image and audio data.
Innovation Solution
A wearable apparatus equipped with a microphone and processor that captures and processes audio signals to identify words and provide feedback to the user, and optionally includes an image sensor for capturing and analyzing images, allowing for enhanced interaction with the environment through augmented reality displays and object recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wearable devices are made small and light for easy wearing, then ease of operation is improved, but processing capability and functionality are reduced
Solution Approach 1:
The patent introduces a separate processing system (smartphone or cloud server) that acts as an intermediary between the wearable device and the user. The wearable captures audio/images and transmits them to the external processing system, which performs complex analysis and returns results. This mediator handles the processing burden, allowing the wearable to remain small while maintaining advanced functionality.
2Adaptability or versatility
If wearable devices capture and process more data for enhanced functionality, then adaptability is improved, but energy consumption increases
Solution Approach 1:
The patent implements selective processing where only relevant audio segments or image frames are captured and transmitted for processing. Instead of continuously processing all captured data, the system identifies and processes only those portions that contain meaningful information (e.g., when a name is mentioned, when a face is detected), thereby reducing overall energy consumption while maintaining enhanced functionality.
3Productivity
If real-time feedback is provided to users based on captured data, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent divides the feedback system into distinct functional segments: audio capture by microphone, image capture by camera, processing by external system, and feedback delivery through display or speaker. Each component performs a specific task independently, and the system integrates these segmented functions to provide real-time feedback without requiring any single component to be overly complex.
Data Source
AI summary
System and methods for processing audio signals are disclosed. In one implementation, a system may include at least one microphone configured to capture sounds from an environment of a user; and at least one processor. The processor may be programmed to receive at least one audio signal representative of at least part of the sounds captured by the microphone; identify at least one word in the at least one audio signal; and in response to identifying the at least one word, cause feedback to be provided the user.
