Vehicular Electronic Device Gaze-Based Video Telephony Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous vehicles, there is a need to limit the video telephony function based on driving conditions to ensure safe driving and protect passenger privacy, as unspecified individuals may ride in sharing vehicles and manual driving modes require attention from the user.
Innovation Solution
A vehicular electronic device that uses a processor to determine the user's gaze direction, allowing voice-only calls when the user looks forward and voice and image calls when they do not, thereby controlling the video telephony function based on driving mode and passenger presence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video telephony function is provided in autonomous vehicle, then user convenience is improved, but driving safety may be compromised when user looks forward
Solution Approach 1:
The system dynamically adjusts video telephony functionality based on real-time detection of user gaze direction. When the user looks forward (indicating manual driving attention), video calling is restricted to voice only. When the user looks away (indicating autonomous driving mode), full video telephony is enabled. This dynamic adaptation resolves the contradiction by making the system flexible rather than static.
Solution Approach 2:
The system changes the operational parameters of video telephony based on detected conditions. The gaze direction detection triggers parameter changes in the telephony function - switching between voice-only mode and full video mode. This parameter adjustment allows the system to optimize both safety and convenience depending on the current driving state.
2Ease of operation
If video telephony is enabled in sharing autonomous vehicle, then user convenience is improved, but privacy of other passengers is invaded
Solution Approach 1:
The system applies different quality levels of video telephony to different spatial locations or user configurations. When multiple passengers are present, the system selectively enables video functionality only for the active caller while maintaining privacy for other passengers. This local differentiation allows video telephony to be provided without universal privacy invasion.
Solution Approach 2:
The system dynamically controls video telephony based on passenger presence detection. When unspecified individuals or multiple passengers are detected in a sharing vehicle, the system adjusts video telephony permissions to protect privacy while still allowing the calling function. This dynamic control resolves the contradiction between providing video telephony and protecting passenger privacy.

AI summary
Disclosed is a vehicular electronic device including a processor configured to receive information on a user gaze direction, to determine whether a user looks forward based on the information, to perform control to make a call using voice only upon determining that the user looks forward, and to perform control to make a call using voice and an image upon determining that the user does not look forward.
