Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D display technologies struggle to adapt dynamically to user presence and gaze direction, often leading to uncomfortable viewing experiences when transitioning between 2D and 3D modes.
Innovation Solution
An electronic apparatus equipped with a camera and processor that uses artificial intelligence models to detect user presence and gaze direction, switching between 2D and 3D modes based on user interaction and content analysis, utilizing a light field display with adjustable lenticular lenses for optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display operates in 3D mode continuously to provide immersive viewing experience, then the user experience is improved, but energy consumption increases and user comfort deteriorates when user is not present
Solution Approach 1:
The display dynamically switches between 3D and 2D modes based on real-time detection of user presence and gaze direction. The system transitions from a static 3D mode to a dynamic mode that adapts to user conditions, reducing energy consumption when no user is present while maintaining 3D experience when needed.
Solution Approach 2:
The system uses cameras and processors to continuously monitor user presence and gaze direction, feeding this information back to control the display mode. This feedback mechanism ensures the display operates in 3D mode only when a user is actually present and engaged, avoiding unnecessary energy consumption.
2Adaptability or versatility
If the display switches between 2D and 3D modes frequently to adapt to user needs, then user comfort is improved, but viewing comfort deteriorates due to mode transition disruptions
Solution Approach 1:
The system performs preliminary detection of user presence and gaze direction before switching modes. By anticipating user needs through continuous monitoring, the system can prepare for mode transitions in advance, minimizing disruptions and maintaining viewing comfort during the switching process.
Solution Approach 2:
Real-time feedback from cameras tracking user gaze and presence allows the system to make informed decisions about mode switching. This feedback mechanism ensures transitions occur only when necessary and appropriate, maintaining viewing comfort while adapting to user needs.
3Adaptability or versatility
If the display uses AI models and cameras for user detection to enable intelligent mode switching, then adaptability is improved, but device complexity increases
Solution Approach 1:
The camera system serves multiple functions: detecting user presence, determining gaze direction, and triggering mode switches. This multi-functionality reduces the need for separate dedicated sensors for each function, thereby limiting the increase in device complexity while maintaining high adaptability.
Solution Approach 2:
The system uses its own integrated cameras and processors to perform self-detection of user presence and gaze, enabling autonomous decision-making about display mode. This self-service capability eliminates the need for external control systems, keeping the overall device complexity manageable.

AI summary
An electronic apparatus including a display that is operable in a 3D mode and a 2D mode; a camera to capture an image in front of the display; a memory storing at least one instruction; and a processor to execute the at least one instruction to identify whether a user is positioned in front of the display based on the captured image, when the user is identified as being in front of the display, identify whether a user gaze is directed toward a front of the display, when the user gaze is identified as being directed toward the front of the display, control the display to operate in the 3D mode, and, when the user is not identified as being in front of the display, or the user gaze is identified as not being directed toward the front of the display, control the display to operate in the 2D mode.
