Projector with Dynamic Orientation Control for Variable Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies, such as those described in International Patent Publication No. WO 2020/031740, face challenges in enhancing user convenience when the projector's projection direction is variable, as they do not effectively determine the optimal projection position and orientation based on environmental and user information.
Innovation Solution
A display method and system that utilize sensors to identify users and determine their positions, combining this information with environmental data to adjust the projection direction and content type, allowing the projector to project image light towards a predetermined direction controlled by a processor and drive device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector projection direction is made variable to adapt to different environments, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The projector is equipped with a drive device that enables dynamic adjustment of the projection direction. The projector can change its projection angle and orientation based on detected user position and environmental conditions, transforming from a static to a dynamic system that adapts in real-time
Solution Approach 2:
The system incorporates sensors to detect user position and environmental information, processes this data to determine optimal projection parameters, and feeds back control signals to the drive device to adjust the projection direction. This closed-loop feedback mechanism enables automatic adaptation without manual intervention
Solution Approach 3:
The projector system integrates multiple functions including projection, sensing, processing, and driving mechanisms into a single unified device. This multi-functional design allows the projector to perform both content delivery and environmental adaptation without requiring separate dedicated devices
2Ease of operation
If sensors and processing are added to determine user position and adjust projection, then user convenience is improved, but device complexity increases
Solution Approach 1:
The projector system automatically detects user position through sensors, processes the information to determine optimal projection parameters, and adjusts itself without requiring user intervention. The system serves itself by autonomously adapting to environmental conditions and user location
Solution Approach 2:
The system performs preliminary detection of user position and environmental conditions before projection begins, pre-calculates the optimal projection direction and content type, and prepares the drive device in advance. This preliminary action ensures seamless user experience without delays during actual use

AI summary
A display method includes obtaining first information for identifying a user, based on output of a first sensor, obtaining second information which is related to a position of the user, based on output of a second sensor, determining a first direction based on the second information, determining a type of an image based on a combination of the first information and the second information, and projecting image light representing the image of the type toward the first direction with a projector.
