Electronic Device Projection Control for Context-Aware Appliance Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional movable projectors lack the ability to project images and information that suit a user's intention and intuition, failing to consider the types of home appliances, user interactions, and environmental factors when determining projection areas.
Innovation Solution
An electronic device equipped with a communicator, camera, and processor that identifies projection areas based on state information and related information of external devices, such as home appliances, to project screens effectively and efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a movable projector projects images on surfaces of home appliances without restriction on location, then the versatility and adaptability of the projector is improved, but the appropriateness and suitability of projected information may deteriorate
Solution Approach 1:
The system performs preliminary detection and analysis of the projection surface and environment before projecting images. The processor detects the type of surface (e.g., wall, ceiling, home appliance), determines appropriate projection content based on the detected environment, and prepares the projection parameters in advance to ensure appropriate and suitable image projection.
2Quantity of substance
If the projector displays information on home appliances with displays, then the information display capability is improved, but the user experience and intuition may deteriorate due to restrictive display sizes and types
Solution Approach 1:
The system transitions from displaying information only on the home appliance's own surface to projecting information on surrounding surfaces and environments. By utilizing the three-dimensional space around the appliance (walls, ceilings, adjacent surfaces), the system overcomes the display size and type restrictions of the appliance itself, providing more versatile and user-friendly information display.
3Extent of automation
If the movable projector operates autonomously without user intervention, then the automation level is improved, but the ability to understand user intention and provide targeted information may deteriorate
Solution Approach 1:
The system incorporates feedback mechanisms where the processor continuously detects the projection environment, analyzes the surface characteristics, and adjusts the projection content accordingly. This feedback loop enables the autonomous projector to understand contextual information and adapt its behavior to match user needs and intentions without requiring direct user intervention.
