Foldable Display Translation Controls for Secure Multilingual Conversations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable display devices struggle to provide secure and efficient multilingual translation services in public spaces, particularly when interacting with strangers, due to background noise interference and potential unauthorized device control.
Innovation Solution
A foldable display device with touch-enabled and touch-disabled portions, enhanced by camera-based noise filtering and dynamic brightness adjustment, along with optional communication with computerized glasses for power conservation and secure translation rendering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire display interface is made touch-enabled for user interaction, then ease of operation is improved, but security against unauthorized control deteriorates
Solution Approach 1:
The display interface is divided into multiple portions with different touch responsiveness settings. The first portion (facing the user) remains touch-enabled for normal interaction, while the second portion (facing others) operates in touch-disabled mode to prevent unauthorized control, thus resolving the contradiction between ease of operation and security
2Measurement precision
If audio recording is continuously performed to capture speech for translation, then translation accuracy is improved, but harmful factors from background noise worsen
Solution Approach 1:
The system uses camera feedback to monitor the speaker's mouth movements and synchronize audio recording with actual speech moments. By comparing visual speech detection from the camera with audio signals, the system selectively records only during genuine speech events, improving translation accuracy while filtering out background noise
3Ease of operation
If the display interface maintains high brightness for visibility, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The display brightness is dynamically adjusted based on detected speech activity. During active translation moments when the display is needed for visibility, brightness is maintained at higher levels. During silent intervals or when translation is not actively occurring, brightness is reduced to conserve energy, thus resolving the contradiction between visibility and energy consumption

AI summary
Implementations set forth herein relate to an automated assistant and/or other application that can adapt settings of a foldable display interface of a computing device according to user interactions occurring during a multilingual conversation. During the multilingual conversation between at least two users, translated content of the conversation can be rendered at a portion of the display interface according to which user is actively speaking. When a user is actively speaking, a brightness level of a portion of the display interface that is facing another user in the conversation can be modified to emphasize that the user is speaking and that the translated content is being rendered. When the user who is speaking is also the owner of the computing device, a portion of the display interface that is facing the other user can exhibit a limited responsiveness to touch inputs.
