Projection Device Dynamic Image Positioning

Solution Overview

Problem

Existing projection devices struggle to dynamically adjust image projection based on the position and movement of objects and people, often requiring manual intervention or relying on fixed settings, which limits adaptability and user experience.

Innovation Solution

A projection device equipped with a sensor unit, detection unit, and controller that detects moving and stationary objects, allowing for dynamic adjustment of image projection regions and directions based on object positions, enabling automatic adaptation to changes in the environment.

1Adaptability or versatility

If the projection device uses fixed settings for image projection, then the device complexity is reduced, but the adaptability to different objects and positions deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The projection device dynamically adjusts the projection position and image content based on real-time detection of object positions and movement. The controller modifies projection parameters adaptively, transforming a static system into a dynamic one that responds to environmental changes without requiring complex manual reconfiguration

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The projection device automatically detects objects and adjusts projection settings without manual intervention. The sensor unit and controller work together to enable the system to self-adjust projection positions and select appropriate images based on detected objects, eliminating the need for user configuration while maintaining simplicity

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If the projection device manually adjusts image projection position, then the adaptability to object position is improved, but the ease of operation deteriorates

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The projection device automatically detects objects and adjusts projection settings without manual intervention. The sensor unit and controller work together to enable the system to self-adjust projection positions and select appropriate images based on detected objects, eliminating the need for user configuration while maintaining simplicity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The sensor unit continuously monitors object positions and provides feedback to the controller, which automatically adjusts projection parameters. This closed-loop feedback system enables real-time adaptation to object movement and position changes without requiring user input or manual adjustment

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the projection device detects moving objects to adjust projection, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:

AI summary

A projection device according to the present disclosure includes a sensor unit (for example, a camera), a detection unit, a controller and a projection unit. The sensor unit detects an object. The detection unit detects a moving object (for example, a person), a first object, and a second object based on a signal output from the sensor unit. The controller generates a projection image such that a first image corresponding to the first object is projected on a first projection region and a second image corresponding to the second object is projected on a second projection region. In this case, the first image is determined based on a position of the moving object, and the second image is determined without depending on a position of the moving object. The projection unit projects the projection image.
