Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing data transfer methods are used in XR systems, then data transfer functionality is provided, but the interaction becomes unintuitive and awkward
Solution Approach 1:
The patent replaces traditional mechanical interaction methods (touchscreens, physical buttons, wired connections) with optical and spatial-based interaction. Visual codes (QR codes, AR markers) are used instead of physical connectors, and head pose tracking replaces manual device handling. This substitution makes data transfer more intuitive by leveraging the natural XR capabilities of visual recognition and spatial awareness.
Solution Approach 2:
The patent introduces visual codes as an intermediary element between the XR device and the target device. These visual codes serve as a mediator that enables data transfer initiation through visual recognition rather than direct device-to-device interaction. The intermediary simplifies the interaction by providing a clear visual target for the user to focus on.
2Reliability
If traditional data transfer methods are used, then data can be transferred, but security and fraud prevention are insufficient
Solution Approach 1:
The patent implements a feedback mechanism where the XR device continuously monitors head pose and visual code recognition status. The system provides real-time feedback to the user through the XR display, confirming when the visual code is properly recognized and when the target device is correctly identified. This feedback loop enhances security by ensuring that data transfer only occurs when the user intentionally targets the correct device.
Solution Approach 2:
The patent performs preliminary verification of the target device before initiating data transfer. The system uses head pose verification and visual code recognition to pre-validate the intended target, ensuring that the user has correctly identified the recipient device. This preliminary action prevents fraudulent transfers by establishing verification protocols before the actual data exchange occurs.
3Ease of operation
If head tracking and localization capabilities are not leveraged, then simpler systems are used, but data transfer lacks natural interaction
Solution Approach 1:
The patent enables the XR device to automatically perform data transfer initiation based on head pose and visual code recognition. Once the user points the XR device at a visual code, the system automatically identifies the target device, verifies the interaction intent through head pose analysis, and initiates data transfer without requiring additional manual steps. This self-service approach leverages the automated tracking and recognition capabilities to simplify the user experience.
4Reliability
If visual tracking and positioning systems are implemented, then secure and intuitive data transfer is enabled, but system complexity increases
Solution Approach 1:
The patent leverages the multi-functionality of visual tracking and positioning systems. The same SLAM-based localization and head pose tracking infrastructure, originally designed for XR navigation and interaction, is reused for data transfer verification. This universal application of existing XR capabilities avoids the need for separate dedicated security hardware, thereby limiting the increase in system complexity while still achieving enhanced security.

AI summary
Techniques and systems are provided for performing data transfers. For instance, a process can include receiving an indication to perform a data transfer; determining, based on a feature map of an environment, a location of an extended reality (XR) device in the environment; determining a first pose of the XR device; obtaining, from the feature map, location information for a target device in the environment; identifying the target device based on the location and the first pose of the XR device; transmitting, to the target device in response to the indication to perform the data transfer, a request to initiate the data transfer; receiving a second pose of the target device; and performing the data transfer based on the received second pose and the first pose of the XR device.
