Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projectors lack advanced touch interaction capabilities beyond simple menu selection and fail to adapt projection areas based on user needs or environmental factors, such as objects in the projection path.
Innovation Solution
A projector system that includes an image generator, projection adjuster, sensor, and controller to detect gestures for dividing projection areas, adjust projection based on user input, and avoid objects, allowing multiple users to view preferred images and project images on or around objects for aesthetic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single projection area is used, then the device structure is simple, but multiple users cannot view different images simultaneously
Solution Approach 1:
The single projection area is divided into multiple sub-projection areas through gesture-based segmentation. When a user performs a division gesture, the projection area is automatically segmented into multiple regions, allowing different images to be projected simultaneously for multiple users. This resolves the contradiction by enabling multi-user viewing without requiring multiple physical projectors.
Solution Approach 2:
The projection area configuration is made dynamic and adjustable based on user needs. The system allows real-time switching between single-area and multi-area modes through gesture inputs, and each divided area can be independently adjusted. This dynamic adaptability enables the system to transform from a simple single-area projector to a versatile multi-user system as needed.
2Adaptability or versatility
If the projection area is fixed, then the device operation is simple, but the system cannot adapt to objects in the projection path
Solution Approach 1:
The system performs automatic object detection and adaptive projection area adjustment without requiring manual intervention. The detector automatically identifies objects in the projection path, and the processor automatically recalculates and adjusts the projection area to avoid objects or project around them. This self-service capability enables environmental adaptation while maintaining simple operation for users.
Solution Approach 2:
The system implements a feedback loop where the detector continuously monitors the projection environment, detects objects, and provides information to the processor. The processor then adjusts the projection area based on this feedback, creating an adaptive system that automatically responds to environmental changes. This feedback mechanism enables the projection area to dynamically adapt to objects while keeping the user interface simple.
3Adaptability or versatility
If conventional touch interaction is used, then the operation method is familiar, but the interaction capability is limited to menu selection
Solution Approach 1:
The gesture detection system serves multiple functions: basic menu navigation, projection area division, area adjustment, and object avoidance commands. By making the gesture interface universal and multi-functional, the system provides enhanced interaction capabilities without requiring separate control mechanisms for each function, thus managing complexity while increasing versatility.
Solution Approach 2:
The sensor acts as an intermediary between the user and the projection system, translating various gesture inputs into meaningful commands. This intermediary layer handles the complexity of gesture recognition and interpretation, allowing users to interact naturally while the system manages the sophisticated processing required for division commands, area adjustment, and object avoidance.
4Adaptability or versatility
If the projection area is divided into multiple areas, then multiple users can view different images, but the control system becomes more complex
Solution Approach 1:
The projection control system is segmented into independent modules, each responsible for controlling a specific projection area. When the area is divided, each sub-area can be controlled independently through separate gesture commands. This modular segmentation allows multi-area projection capability while managing system complexity through functional decomposition.
Solution Approach 2:
The number and configuration of projection areas are made dynamic rather than fixed. The system can seamlessly transition between single-area and multi-area modes based on user gestures, and each area can be independently adjusted or merged. This dynamic flexibility enables multi-user viewing capability while keeping the control system adaptable rather than permanently complex.

AI summary
A projector includes: an image generator configured to generate an image; a projection adjuster configured to adjust a projection area onto which the image is projected; a sensor configured to detect a gesture input for the projection area; memory storing instructions; and a processor configured to execute the instructions, wherein the instructions, when executed by the processor, may cause the projector to, based on the gesture input being a division command for the projection area, control the projection adjuster such that the image is projected onto divided projection areas as divided.
