Mirror Display Breath Gesture Control for Interactive Drawing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with mirror displays lack the ability to seamlessly transition between mirror and display functions while accommodating user interactions, such as breath-based gestures, for enhanced user engagement and functionality.
Innovation Solution
The electronic apparatus incorporates sensors to detect user proximity and breath, allowing it to switch to an opaque drawing state and adjust opacity based on user gestures, enabling interactive drawing functions on the mirror display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mirror display operates in mirror state with high reflectivity, then mirror function is provided, but display function and user interaction are limited
Solution Approach 1:
The mirror display dynamically adjusts its state between mirror mode and opaque drawing mode based on detected breath intensity. The display panel changes from a reflective state to an opaque state with drawing functionality, allowing the device to adapt its function based on user interaction without requiring complex manual controls
Solution Approach 2:
The system automatically detects user proximity and breath gestures through sensors, and autonomously transitions between mirror and drawing functions without requiring explicit user commands. The breath detection trigger mechanism enables the display to self-initiate function switching based on passive sensing of user presence and gestures
2Adaptability or versatility
If the mirror display switches to opaque drawing state, then drawing function is enabled, but mirror reflectivity is reduced
Solution Approach 1:
The display implements local opacity control where only the region corresponding to the user's breath gesture becomes opaque for drawing, while other areas maintain their mirror reflectivity. This allows simultaneous preservation of mirror functionality in non-interaction zones while enabling drawing in the targeted interaction zone
Solution Approach 2:
Instead of making the entire display opaque for drawing mode, the system applies opacity only to the specific region where drawing is needed, based on breath detection. This partial action approach maintains overall display versatility while minimizing the loss of mirror reflectivity in non-drawing areas
3Ease of operation
If breath detection is used to control opacity, then user engagement is enhanced, but sensor requirements and system complexity increase
Solution Approach 1:
The system replaces traditional mechanical or manual control interfaces with breath-based gesture recognition. Sensors detect breath patterns (such as CO2 concentration or air flow) to infer user intent for drawing actions, substituting physical contact or complex button sequences with a more natural, contactless interaction modality
Solution Approach 2:
The breath detection system serves as an intermediary between the user and the display function. Rather than direct manual control, the user's breath acts as a medium that the sensors detect and translate into drawing commands, creating a natural bridge between human intent and device response

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 predetermined 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.
