Projector Posture Change Detection and Alert System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Projectors installed on ceilings, walls, or desks often experience posture changes, leading to fluctuations in image quality and potential malfunctions, which existing technologies fail to effectively monitor or correct.
Innovation Solution
A projector system that acquires and compares imaging information at different timings to evaluate posture changes, using an evaluation section to determine if the change meets certain criteria, and outputs information to alert users or adjust the installation accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a projector is installed on a ceiling, wall, or desk, then the projector can be positioned for projection, but the posture of the projector may change over time leading to image quality fluctuations
Solution Approach 1:
The system performs preliminary posture evaluation by capturing images at multiple timings and comparing them to detect posture changes before they significantly degrade image quality. The evaluation section assesses whether posture change amounts exceed predetermined thresholds, enabling early intervention through user notifications or automatic corrections.
Solution Approach 2:
The system establishes a feedback loop by continuously monitoring projector posture through image capture and evaluation, then providing output based on evaluation results. This feedback mechanism allows the system to detect posture changes and trigger corrective actions, such as notifying users or automatically adjusting the projector, thereby maintaining image quality stability.
2Adaptability or versatility
If the projector posture changes, then the projector may adapt to new positions, but image quality fluctuates and malfunctions may occur
Solution Approach 1:
The system dynamically evaluates projector posture by capturing images at different timings and comparing posture changes. The evaluation section determines whether posture changes exceed predetermined thresholds, enabling the system to adapt to legitimate position changes while detecting problematic posture shifts that may cause malfunctions. This dynamic approach allows the projector to maintain reliability while accommodating necessary position adjustments.
3Ease of manufacture
If existing ceiling suspenders are used to suspend the projector, then installation is simplified, but the projector posture may still change
Solution Approach 1:
The system provides self-service posture monitoring and evaluation, automatically detecting posture changes through image capture and comparison without requiring external monitoring equipment. The evaluation section autonomously assesses whether posture changes exceed thresholds and generates appropriate output, enabling the projector to self-diagnose and alert users to posture issues even when installed with simple suspenders.

AI summary
A projector controlling method includes acquiring first imaging information obtained by capturing a first image projected from a projector at a first timing, acquiring second imaging information obtained by capturing a second image projected from the projector at a second timing, evaluating whether or not a change in the posture of the projector satisfies a certain criterion based on the first imaging information and the second imaging information, and outputting information based on the result of the evaluating.
