Projector Device Dynamic Guidance Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector devices lack the ability to dynamically adjust guidance information in projection images based on the movement and state of a target object, such as a person, to effectively provide guidance or advertisements in real-time.
Innovation Solution
A projector device equipped with first and second detectors, a projector unit, and a controller that tracks the target object, changing the content of the projection image according to the object's state, allowing for dynamic guidance and advertisement delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the projector device uses a fixed projection image, then the device complexity is reduced, but the adaptability to target object movement and state changes deteriorates
Solution Approach 1:
The projection image transitions from a static fixed image to a dynamic image that automatically adjusts its content based on the detected state and movement of the target object. The controller modifies the projection image in real-time according to detector inputs, making the system adaptive without requiring complex mechanical reconfiguration.
Solution Approach 2:
The system implements a feedback loop where detectors continuously monitor the target object's state and movement, and the controller uses this information to adjust the projection image content. This closed-loop control enables the projector to respond automatically to changes in the target object without manual intervention.
2Productivity
If the projector device projects static guidance information, then the ease of operation is improved, but the effectiveness of guidance delivery deteriorates
Solution Approach 1:
The guidance information in the projection image becomes dynamic, automatically updating based on the target object's movement and state. This allows the system to deliver more effective guidance without requiring manual adjustment, as the content adapts automatically to the situation.
Solution Approach 2:
The projector system performs self-adjustment of the projection image content based on detector feedback about the target object. The system serves itself by automatically modifying the guidance information without requiring external control or manual intervention, improving both effectiveness and ease of operation.
3Adaptability or versatility
If the projector device uses a single fixed projection image, then the loss of information is reduced, but the adaptability to different target object states deteriorates
Solution Approach 1:
The projection image content dynamically adapts to different target object states (movement, position, orientation) while maintaining complete and accurate guidance information. The system selects and presents the most appropriate guidance content for each detected state, preventing information loss by providing state-specific relevant information rather than a single fixed image.
Solution Approach 2:
Different regions or aspects of the projection image provide different types of guidance information tailored to the specific detected state of the target object. The system adjusts the content locally within the projection image to match the target's current state, ensuring that the most relevant information is always presented.
Data Source
AI summary
A projector device includes a distance detector, an imaging unit, a projector unit, a driver, and a controller. The imaging unit detects a specific target object. The projector unit projects a projection image. The driver drives the projector unit such that a projection direction in which the projection image is to be projected is changed. The distance detector detects a state of the target object detected by the imaging unit. The controller controls at least one of the projector unit and the driver such that the projection image tracks the target object. The projection image has display data including a content for guiding the target object. The controller changes a content of information included in the display data in the projection image, which is to be projected while tracking the target object, according to the state of the target object detected by the distance detector.
