Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection technologies, such as external displays and smart audio devices, are not ideal for presenting information in certain contexts, as they do not adapt to the user's viewing context, leading to suboptimal information delivery.
Innovation Solution
A system comprising a processor, sensors, and steerable projectors that determine the user's field of view and target viewing surface characteristics to project audiovisual content effectively, adjusting parameters like color and size for optimal viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external displays or smart audio devices are used to present information, then information can be delivered to users, but the information delivery is suboptimal in certain contexts because these devices do not adapt to the user's viewing context
Solution Approach 1:
The projection system dynamically adjusts its operation based on real-time detection of user field of view and viewing context. The projector transitions from a static device to an adaptive system that continuously modifies projection parameters (position, orientation, content) based on sensor feedback about user gaze and environmental conditions.
Solution Approach 2:
The system incorporates sensors that detect user field of view and viewing context, feeding this information back to the projection control system. This closed-loop feedback mechanism enables the projector to automatically adjust its behavior to match user needs, resolving the contradiction between adaptability and information delivery effectiveness.
2Ease of operation
If traditional projection systems are used, then audiovisual content can be displayed, but the systems lack the capability to automatically adjust to user field of view and viewing context
Solution Approach 1:
The projection system performs self-adjustment by automatically detecting user field of view and viewing context through integrated sensors, then autonomously modifying projection parameters without requiring manual user input. This eliminates the need for hands-on control while managing complexity through integrated sensor-processing-projection workflows.
Solution Approach 2:
The system replaces manual mechanical adjustment mechanisms with automated sensor-based detection and control. Instead of requiring users to physically adjust projector position or settings, the system uses optical sensors and processors to automatically determine and execute optimal projection configurations.
3Manufacturing precision
If projection parameters are manually adjusted, then viewing quality can be optimized, but this requires manual input and reduces usability when users need to perform manual tasks
Solution Approach 1:
The system automatically optimizes projection parameters by detecting user field of view and viewing context through integrated sensors, eliminating the need for manual adjustment. This self-optimizing capability maintains high projection quality while allowing users to focus on their manual tasks without interruption.
Solution Approach 2:
The system performs preliminary detection of viewing context and pre-adjusts projection parameters before the user actually needs to view the content. By anticipating viewing requirements through field-of-view detection, the system prepares optimal projection settings in advance, ensuring immediate quality without requiring reactive manual adjustment.

AI summary
Apparatuses, methods, systems, and computer program products are disclosed for controlling projection based on viewing context. An apparatus, in one embodiment, includes a processor and a memory that stores code executable by the processor to determine whether a predetermined condition is satisfied for projecting audiovisual content to a user in a selected viewing context. The apparatus may include sensors that communicates to the processor, parameters of the field of view of the user for the selected viewing context and characteristics of a target viewing surface within the field of view. The apparatus, further includes at least one steerable projector this is controlled, based on the one or more parameters, to project a video portion of the audiovisual content on to the target viewing surface, in response to the processor determining that the predetermined condition is satisfied. Systems, computer program products, and methods may perform the functions of the apparatus.
