Mirror Display Opacity Control for Breath-Activated Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices with mirror displays lack the ability to seamlessly transition between mirror and display functions while accommodating user interactions, such as breath-based inputs for drawing or gesture recognition, without compromising functionality.
Innovation Solution
An electronic apparatus equipped with sensors and processors that detect user proximity and breath to control the mirror display's opacity and adjust drawing functions based on user gestures, allowing for a dynamic transition between mirror and display states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mirror display operates in mirror state to provide reflection function, then the reflectivity is maintained, but the user cannot interact with drawing functions or view displayed content
Solution Approach 1:
The patent applies dynamics by enabling the mirror display to dynamically switch between mirror state and opaque state based on user interaction. The display transitions from a reflective surface to an opaque drawing surface when the user approaches and interacts, allowing seamless adaptation between viewing and interaction modes without manual configuration
Solution Approach 2:
The patent changes the optical parameter (opacity) of the display based on detected breath intensity. When the user exhales toward the display, the system adjusts the opacity parameter to transition from transparent/mirror state to opaque state, enabling drawing functionality. This parameter change allows the same physical display to serve multiple functions
2Adaptability or versatility
If the mirror display transitions to opaque state for drawing function, then the drawing capability is enabled, but the mirror reflection function is lost in that area
Solution Approach 1:
The patent applies local quality by making only the specific area where the user exhales opaque, while the rest of the mirror display maintains its reflective properties. This localized state change allows the user to draw on a specific region without affecting the mirror function of the entire display surface
Solution Approach 2:
The opacity state is dynamically adjusted based on real-time breath detection. When the user stops exhaling, the display area returns to its mirror state, allowing automatic transition between functions based on interaction duration and intensity
3Measurement precision
If the system uses sensors to detect breath and gestures, then the user interaction precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces traditional mechanical or manual interaction interfaces with breath-based detection. Instead of requiring physical contact with the display surface or complex gesture recognition systems, the invention uses breath detection to trigger and control drawing functions, simplifying the interaction mechanism while maintaining precision
Solution Approach 2:
The system uses the user's own breath as the interaction medium, eliminating the need for external controllers or complex input devices. The breath itself serves as the control signal, making the system more intuitive and reducing the complexity of external interaction mechanisms

AI summary
An electronic apparatus including a mirror display, a sensor, memory storing one or more instructions, and one or more processors connected to the mirror display, the sensor and the memory to control the electronic apparatus. The one or more processors are configured to, by executing the one or more instructions, based identifying that a user's face approaches the mirror display within a threshold distance based on first data obtained via the sensor when the mirror display is in a mirror state and that the user exhales based on second data obtained via the sensor, control the mirror display to enter a drawing state by processing an area of the mirror display to be opaque based on the second data, and control the mirror display so that reflectivity of an area corresponding to a user gesture input in the opaque area increases.
