Smart Glasses Audio Sync for Multi-View Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display apparatuses and glasses systems struggle to provide an audio experience for a single selected content among multiple displayed contents, especially in multi-view modes, where users need to listen to the audio of their chosen content without interference from other users' content.
Innovation Solution
A glasses apparatus with a first interface module for receiving synchronization signals, a second interface module for receiving audio signals, a controller to select the audio signal of the chosen content, and an audio outputter integrated within the glasses frame to output the selected audio signal, using wireless communication methods like Bluetooth, RF, or infrared.

Engineering Contradiction Analysis
1Adaptability or versatility
If a display apparatus displays multiple contents simultaneously for multiple users, then the quantity of content access is improved, but the ability to provide dedicated audio for a single selected content deteriorates
Solution Approach 1:
The audio output function is segmented and assigned to individual glasses apparatuses rather than being centralized in the display apparatus. Each glasses apparatus independently receives and outputs audio for its associated content, enabling users to selectively listen to their chosen content without interference from other users' content.
Solution Approach 2:
The glasses apparatus serves as an intermediary device between the display apparatus and the user's ears. It receives synchronization signals and audio signals from the display apparatus, processes them, and outputs the audio through integrated earphones, thereby enabling selective audio output for multi-view mode operation.
2Ease of operation
If audio signals are transmitted wirelessly to glasses apparatus, then the ease of operation is improved, but the reliability of audio synchronization with display timing deteriorates
Solution Approach 1:
The glasses apparatus receives and processes the synchronization signal in advance to determine the exact timing for audio output. By using the synchronization signal to control when audio is output, the system ensures that audio is transmitted wirelessly at the precise moment needed to match display timing, maintaining reliability while enabling wireless operation.

AI summary
A glasses apparatus which works in conjunction with a display apparatus which operates in a multi-view mode to combine and output a plurality of contents. The glasses apparatus includes: a first interface module which receives a synchronization signal in a first wireless communication method; first and second glasses mounted on a glasses frame and which are driven in synchronization with one of the plurality of contents based on the synchronization signal; a second interface module which receives an audio signal of at least said one content in a second wireless communication method; a controller which selects an audio signal of said one content from among audio signals corresponding to the plurality of contents, and an audio outputter which outputs the audio signal of the selected content, and which is integrally formed with the glasses frame.
