3D AR World Synthesis via Cloud Rendering and Sensor Fusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current augmented reality technologies lack the ability to create and share a seamless, realistic 3D augmented reality world across multiple devices and platforms, limiting the communal experience and realism of virtual objects in physical spaces.
Innovation Solution
The system generates and shares a 3D AR world by synthesizing inputs from various devices, using sensors like GPS, accelerometers, and gyroscopes, and employing peer-to-peer communication and cloud-based servers to render high-quality, real-time environmental effects, ensuring consistency and realism across different vantage points and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a shared 3D AR world is created by synthesizing inputs from multiple devices, then the realism and communal experience are improved, but the device complexity and computational requirements increase
Solution Approach 1:
The system divides the complex AR world synthesis task into separate functional modules: device input collection, sensor data processing, 3D object rendering, and communication protocols. Each device independently contributes specific sensor inputs (GPS, accelerometer, gyroscope) that are synthesized into a unified 3D AR experience, reducing individual device complexity while maintaining overall realism
Solution Approach 2:
A server acts as an intermediary that receives and synthesizes inputs from multiple devices, processes the sensor data, and generates the 3D AR world. This mediator handles the computational complexity centrally, allowing individual devices to remain relatively simple while still participating in the shared realistic AR experience
2Illumination intensity
If high-quality real-time environmental effects are rendered across multiple devices, then the visual realism is improved, but the energy consumption and processing power requirements increase
Solution Approach 1:
The server serves as an intermediary that performs the computationally intensive task of rendering high-quality environmental effects (sunlight, shadows, weather) and distributes the rendered content to multiple devices. This eliminates the need for each device to independently perform heavy rendering calculations, thereby reducing individual device energy consumption while maintaining visual realism
Solution Approach 2:
The system creates a master rendered version of the 3D AR world with high-quality environmental effects on the server, then distributes copies of this rendered content to multiple devices. Each device receives and displays the pre-rendered visual effects rather than generating them locally, significantly reducing the energy and processing requirements at the device level
3Adaptability or versatility
If the 3D AR world is made accessible on a wide range of devices, then the versatility and user accessibility are improved, but the manufacturing precision and synchronization accuracy decrease
Solution Approach 1:
The system implements a universal communication protocol and data format that enables diverse devices (smartphones, tablets, wearables) with different sensors and capabilities to participate in the shared 3D AR world. The server adapts and synthesizes inputs from various device types, allowing broad device compatibility while maintaining a consistent and accurate spatial experience through centralized coordination

AI summary
A 3-dimensional augmented reality (AR) world is a version of our “real” physical world augmented with virtual 3D objects that may be experienced by a user, such as someone who “sees” the virtual 3D objects through a smartphone or special eyewear. A shared 3D AR world is one in which multiple individuals can simultaneously experience the same augmented reality, even if they are not using the same devices. The shared 3D AR world is created by obtaining and synthesizing sensory and other inputs from various devices in use by different users, and providing augmented outputs adapted to different devices. The synthesis of a wide range of inputs allows the augmented reality effects to be realistic. The augmented reality effects may be pre-rendered by a cloud-based server to reduce the computational burden on user devices.
