Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not allow for direct and effective visualization of the interaction between a physical object and a 3-D image without auxiliary means, limiting the immersive experience.
Innovation Solution
An apparatus comprising a display device, a projection device, and an acquisition device that captures and determines the distance between a physical object and a reference position on a display device, triggering an optical projection when the distance is less than a defined minimum, allowing for improved visualization of the interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sensor-based capture and software merging are used to simulate interaction, then interaction visualization is enabled, but the immersion and directness of the interaction experience are reduced
Solution Approach 1:
The patent introduces optical projection as an intermediary medium that bridges the physical object and the 3-D image. Instead of relying solely on sensor-based simulation, the system projects optical patterns onto the physical object to create a direct visual connection, enhancing the immersive experience while maintaining interaction visualization
Solution Approach 2:
The patent merges multiple technologies - display device, acquisition device, and projection device - into an integrated system. This combination allows the system to simultaneously capture physical object data, generate 3-D images, and project optical patterns, creating a unified interaction experience that reduces the loss of immersion
2Measurement precision
If distance determination and conditional projection are implemented, then interaction precision is improved, but device complexity increases
Solution Approach 1:
The acquisition device serves multiple functions: it captures images of the display device, captures images of the physical object, determines distances between them, and triggers projections based on distance thresholds. This multi-functionality reduces the need for separate dedicated components for each function, thereby managing device complexity while maintaining measurement precision
3Loss of information
If optical projection is used to enhance visualization, then interaction visibility is improved, but energy consumption increases
Solution Approach 1:
The projection is not continuous but is triggered periodically or conditionally based on distance measurements. The system determines the distance between the physical object and display device, and only activates projection when the object enters a predetermined interaction zone. This periodic/conditional activation reduces overall energy consumption while maintaining interaction visibility when needed

AI summary
An apparatus for visualizing an interaction of a physical object with a 3-D image includes a display device, a first projection device, an acquisition device, and an evaluation device. The display device presents the 3-D image which is perceivable by a user. The first projection device projects a first optical display onto a first region of the physical object. The acquisition device captures first object data of the display device and second object data of the physical object that is spaced apart from the display device and movable. The acquisition device determines a distance between a reference position formed on a surface of the display device and the physical object using the first object data and the second object data. The evaluation device is signal-connected to the acquisition device and the first projection device, and triggers the projection of the first optical display by the first projection device responsive to a condition in which the determined distance is less than a minimum distance defined in advance.
