Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three-dimensional viewing technologies, such as stereoscopic, VR, and AR, are cumbersome, require special equipment, and do not dynamically adjust perspectives based on user position and movement, failing to integrate virtual and physical spaces effectively.
Innovation Solution
A system that maps a three-dimensional coordinate space onto physical space, using sensors to detect user position and actions, calculates a frustum based on designated body parts, and dynamically adjusts virtual perspectives based on user movement, allowing interaction without headsets or glasses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If stereoscopic, VR, or AR technologies are used to provide three-dimensional viewing, then a three-dimensional viewing experience is achieved, but the device complexity increases and special equipment is required
Solution Approach 1:
The patent uses sensor data to create a virtual copy of the user's physical body parts (hands, arms, torso) in the three-dimensional scene. This virtual copy allows the system to calculate viewing perspectives without requiring physical headsets or specialized equipment, thereby achieving 3D viewing while reducing device complexity
Solution Approach 2:
The system introduces sensor devices and computational algorithms as intermediaries between the user and the display. Instead of requiring the user to wear VR/AR equipment, sensors capture physical position data and computational algorithms transform this data into perspective adjustments, serving as a mediator that eliminates the need for special viewing equipment
2Shape
If traditional three-dimensional technologies are used, then a fixed perspective is provided, but the adaptability to user position and movement is reduced
Solution Approach 1:
The patent implements dynamic perspective adjustment by continuously monitoring the user's physical position and body orientation through sensors. The viewing perspective in the three-dimensional scene automatically updates in real-time based on detected user movements, transforming the static perspective of traditional 3D technologies into a dynamic, adaptive experience
Solution Approach 2:
The system establishes a feedback loop where sensor data about user position and movement is continuously fed into the perspective calculation algorithm. This feedback mechanism allows the display to automatically adjust the three-dimensional perspective based on real-time user actions, enhancing adaptability without requiring manual intervention
3Device complexity
If virtual and physical spaces are separated, then the viewing technology is simpler, but the integration between virtual and physical spaces is reduced
Solution Approach 1:
The patent merges the physical space (detected by sensors) with the virtual three-dimensional space (displayed on screen) by using physical body position data to directly control virtual perspective. This combining of physical and virtual elements creates a unified experience where the boundary between physical and digital spaces becomes blurred, enhancing integration while maintaining system simplicity

AI summary
Preferred embodiments are directed to systems and methods for generating a three-dimensional scene based on a user's perspective by demarcating an axis of a three-dimensional space through a surface of a display device, whereby one side of the axis is mapped onto a physical space; receiving, by one or more sensor devices, point cloud data from the physical space, the point cloud data being indicative of one or more target objects; computing a likely shape for each of the one or more target objects based on the plurality of captured data points; calculating a frustum based on at least one of the one or more target objects; and displaying, by the display device, a perspective of a three-dimensional virtual scene, the perspective being determined from the calculated frustum.
