Mirror Display Control Using Gaze Detection for Hands-Free Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mirror display technologies require manual operation to change display states, which can be inconvenient for users when their hands are occupied, such as when brushing teeth or applying makeup.
Innovation Solution
A display control apparatus and method that uses a mirror with a display unit behind it, equipped with an image sensor and gaze detection, to automatically control the display state based on user gaze and state, allowing for enhanced convenience by extending the mirror's functionality without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is required to change display state, then display control functionality is achieved, but user convenience deteriorates when hands are occupied
Solution Approach 1:
The mirror display device performs display state changes automatically based on detected user states without requiring manual operation. The system monitors user presence, gaze direction, and other states through sensors, then autonomously adjusts the display to show appropriate content such as full-body images or enlarged views, making the system serve itself rather than requiring user initiation
Solution Approach 2:
The patent replaces manual mechanical operation (button pressing) with automated detection and control systems. Image sensors, gaze detection units, and other sensors substitute for manual user input, detecting user states and triggering appropriate display changes automatically, thereby eliminating the need for mechanical user interaction
2Adaptability or versatility
If display shows regions not visible in optical reflection, then mirror display functionality is extended, but device complexity increases
Solution Approach 1:
The patent merges the optical mirror function with electronic display capabilities into a single integrated device. The mirror display unit combines the reflective surface with a display screen that can show captured images, while the control unit integrates sensor data processing and display control functions, creating a unified system that provides both traditional mirror reflection and extended digital display functionality
Solution Approach 2:
The mirror display device is designed to perform multiple functions: traditional optical reflection, full-body image display, enlarged view display, and gaze-based interaction. The single device serves as both a conventional mirror and a smart display system, providing versatile functionality across different usage scenarios without requiring separate devices
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables automatic adjustment of the display to meet user needs, reducing the burden of manual operation and enhancing user convenience by extending the mirror's functionality to include regions not visible in the optical reflection, such as full-body images or enlarged views, without the need for user input.
Implementation Method 1
a mirror configured to project an optical reflection image onto a front surface thereof
Data Source
AI summary
There is provided a display control apparatus. A mirror is configured to project an optical reflection image onto a front surface thereof and transmit light from behind the mirror. A display is disposed behind the mirror. An image sensor shoots a field of view on the front surface side of the mirror. A controller controls a display state, in the display, of an image acquired by the shooting, based on a state of a user on the front surface side of the mirror.
