Projector Location Sensing for User-Based Image and Voice Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors lack the ability to perform operations suitable for a user's location, relying on simple voice inputs or remote controls without considering the actual viewing location, leading to suboptimal image quality and user interaction.
Innovation Solution
An electronic device that acquires location information of a projection area and the user using sensors, and adjusts operations such as voice recognition and image quality processing based on relative location, including keystone corrections and focus adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector performs operations based on simple voice input or remote control centered on the projector, then the device complexity is reduced, but the adaptability to user location is worsened
Solution Approach 1:
The patent introduces location information as an intermediary parameter that mediates between the user and the projector. Sensors detect user location, and this location data serves as a mediator to automatically adjust projection parameters (keystone correction, focus, zoom) without requiring complex user interactions or increasing device complexity significantly
Solution Approach 2:
The projector performs self-adjustment of projection parameters based on detected user location. The system automatically executes keystone correction, focus adjustment, and zoom operations without user intervention, allowing the device to serve itself in adapting to different viewing positions
2Manufacturing precision
If the projector does not consider actual viewing location, then the ease of operation is improved, but the image quality is worsened
Solution Approach 1:
The system implements feedback by continuously monitoring user location through sensors and using this information to automatically adjust projection parameters. The feedback loop ensures that image quality is optimized for the actual viewing position without requiring manual user adjustments, thus maintaining both high image quality and ease of operation
Solution Approach 2:
The projector performs preliminary adjustment of projection parameters based on predicted or detected user location before the user actually views the projection. By pre-adjusting keystone, focus, and zoom settings according to location data, the system ensures optimal image quality is ready in advance without requiring user intervention
3Adaptability or versatility
If the projector performs location-based operations, then the adaptability to user location is improved, but the use of energy is worsened
Solution Approach 1:
The system performs location-based adjustments periodically or event-driven rather than continuously. Sensors detect user location and trigger projection parameter adjustments only when location changes are detected, rather than continuously monitoring and adjusting, thus reducing energy consumption while maintaining adaptability
