Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing-impaired individuals face challenges in accessing timely information during conversations, especially in environments where conventional subtitle services are limited to screens and require additional device support, leading to increased costs and operational inconvenience.
Innovation Solution
A subtitle display system integrated with augmented reality glasses that captures audio information, performs voice transcription, and displays subtitles in real-time, utilizing a linear microphone array, beamforming technology, and cloud-based transcription to provide personalized and convenient subtitle services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional subtitle services are used on screens, then subtitle display is achieved, but device complexity increases and operational convenience deteriorates due to additional device support requirements
Solution Approach 1:
The patent combines the subtitle display function with the existing augmented reality glasses device, merging the subtitle service with the wearable technology platform. This eliminates the need for separate screen-based subtitle devices and reduces overall system complexity by integrating multiple functions into a single platform.
Solution Approach 2:
The augmented reality glasses are designed to perform multiple functions including audio capture, voice transcription, and subtitle display, making them a universal device that serves both as a communication aid and an entertainment device. This multi-functionality eliminates the need for separate dedicated subtitle devices.
2Loss of time
If conventional subtitle services are provided, then hearing-impaired individuals can access subtitles, but timely access to conversations is limited due to screen restrictions
Solution Approach 1:
The patent transitions subtitle display from the traditional two-dimensional screen interface to a three-dimensional spatial display on augmented reality glasses. This allows subtitles to be projected in the user's field of view, enabling timely access to conversations during audio-visual content without the limitations of fixed screen positions.
Solution Approach 2:
The system provides personalized viewing experience by automatically detecting the user's audio input and generating customized subtitles in real-time. The augmented reality glasses autonomously capture audio, perform voice transcription, and display personalized subtitles without requiring manual configuration or additional device setup.
3Ease of manufacture
If additional device support is required for subtitle services in public places, then subtitle functionality is achieved, but costs increase and operational convenience deteriorates
Solution Approach 1:
The patent merges the subtitle service functionality with the augmented reality glasses, eliminating the need for separate screen-based subtitle devices. This integration reduces hardware costs and simplifies the overall system architecture by combining multiple functions into a single wearable device.
Solution Approach 2:
The augmented reality glasses autonomously perform audio capture, voice transcription, and subtitle display without requiring additional external devices or manual setup. The system self-services the subtitle generation process, reducing both hardware costs and operational complexity for users in public places.

AI summary
Disclosed is a subtitle display method, applied to augmented reality glasses, and the augmented reality glasses are connected to a user terminal. The method includes: capturing, by the augmented reality glasses, a phone audio sent by the user terminal, where the phone audio is used to represent audio information generated during an incoming call or an outgoing call; acquiring, by the augmented reality glasses based on the phone audio, a text corresponding to the phone audio; and displaying, by the augmented reality glasses by using subtitles, the text corresponding to the phone audio. This can provide a subtitle service in augmented reality glasses, improving user experience, especially improving quality of life of a hearing-impaired person.
