Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projectors face challenges in generating high-quality user interfaces due to non-ideal projected regions, such as contamination, occlusion, or irregularities, making it difficult to achieve flexible and effective user interaction without external devices.
Innovation Solution
A method and apparatus that utilize environmental and user body information, including three-dimensional space data, to determine a target projected region and generate a user interface using diffusion models to adapt the layout and appearance based on user intentions, overcoming the limitations of non-ideal surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a projector projects on a reserved region (white wall or curtain) to achieve better projection effect, then the projection quality is improved, but the user cannot flexibly interact with the projected picture without external devices
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture the projected picture and user gestures, enabling touch control functionality without direct physical contact. The camera serves as a mediator between the user's hand movements and the projected interface, allowing interaction while maintaining the projected display quality on reserved regions.
2Adaptability or versatility
If the projected region contains contamination, occlusion or irregularity, then the flexibility of projection location is improved, but the projection effect deteriorates
Solution Approach 1:
The patent applies preliminary action by using the camera to detect and analyze the projected region's characteristics (contamination, occlusion, irregularity) before generating the user interface. This pre-detection allows the system to compensate for regional defects and generate appropriate UI layouts that adapt to the actual projection conditions, maintaining quality even on non-ideal surfaces.
Solution Approach 2:
The patent implements local quality by generating user interface elements with adjusted properties based on the specific characteristics of different regions of the projected surface. The system modifies UI element placement, size, and design to accommodate local irregularities, contamination, or occlusion in specific areas while maintaining overall projection flexibility.
3Ease of operation
If the user operates the projected picture directly without external devices, then the ease of operation is improved, but the system complexity increases to achieve touch control functionality
Solution Approach 1:
The patent applies universality by making the projector system multi-functional - it not only projects images but also captures user gestures through its integrated camera and processes touch control commands. This consolidation of projection, detection, and control functions into a single system reduces the need for separate external devices while enabling direct interaction.
