Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If position-measuring device measures latitude, longitude, and altitude to determine position in virtual space, then position coordinates can be obtained for transformation, but measurement accuracy is insufficient leading to imprecise superimposition of virtual space on real space
Solution Approach 1:
The patent introduces an image capture device as an intermediary to capture images of the wearable device from the real space. These captured images are then processed to determine the position of the wearable device in real space with high accuracy, serving as a mediator between the position-measuring device and the virtual space transformation process.
Solution Approach 2:
The patent replaces the traditional position-measuring device (GPS, altitude meter) with an image-based recognition system. By capturing images and identifying the wearable device in those images, the system substitutes mechanical/electronic position measurement with optical recognition and image processing methods, achieving higher measurement precision.
2Ease of operation
If virtual space coordinates are transformed to real space coordinates using position-measuring device data, then coordinate transformation can be performed, but virtual objects are displayed at incorrect positions due to measurement errors
Solution Approach 1:
The patent uses captured images as an intermediary to bridge the coordinate systems. The image capture device records the wearable device's position in real space, and this visual information serves as a mediator to accurately determine position coordinates for the transformation process, replacing direct reliance on position-measuring device data.
Solution Approach 2:
The patent creates a visual copy of the wearable device through image capture. By capturing and processing images of the wearable device, the system obtains an accurate representation of its real-space position, which is then used for coordinate transformation, ensuring virtual objects are displayed at correct positions.

AI summary
An information processing apparatus includes: an acquirer configured to acquire (i) captured image information indicating an image captured by an image capture device, (ii) image capture position information indicating a position of the image capture device, and (iii) provisional position information indicating a position of a wearable device; an identifier configured to identify, based on the captured image information and the provisional position information, a person wearing the wearable device, from among persons indicated by one or more person images included in the captured image; a calculator configured to calculate self-position information indicating a position of the wearable device worn by the person identified by the identifier, using the image capture position information; and a transmitter configured to supply the self-position information to the wearable device. The image capture position information is higher in accuracy than the provisional position information.
