Wearable Display EDID Rendering for AR/VR Companion Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring electronic devices for seamless operation with wearable glass projection devices, such as augmented and virtual reality companions, is cumbersome due to the lack of standardized methods for determining and rendering content based on their unique specifications like field of view and interpupillary distance.
Innovation Solution
The electronic device queries the companion device to determine its type and obtains slice assignments from extended display identification data (EDID) extensions, including field of view and interpupillary distance, to render content optimally for wearable glass projection devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the electronic device uses standardized configuration methods for companion devices, then the ease of operation is improved, but the adaptability to wearable glass projection devices with unique specifications deteriorates
Solution Approach 1:
The patent changes the parameters used in EDID from traditional display specifications (resolution, refresh rate) to wearable-specific parameters (field of view, interpupillary distance, lens slice assignments). This allows the same EDID framework to adapt to wearable glass projection devices while maintaining standardized operation procedures.
Solution Approach 2:
The patent extends the universal EDID standard to serve multiple functions: it works for traditional displays and simultaneously adapts to wearable glass projection devices by including device type identification and wearable-specific parameters. This multi-functionality resolves the contradiction between standardized operation and device-specific adaptability.
2Manufacturing precision
If the electronic device obtains detailed specification data from EDID extensions, then the manufacturing precision of content rendering is improved, but the device complexity increases
Solution Approach 1:
The patent performs preliminary action by having the wearable glass projection device pre-populate its specification data (field of view, interpupillary distance, slice assignments) into EDID extensions during device initialization. This prepares the data in advance, so the electronic device can directly use it for content rendering without complex real-time processing.
Solution Approach 2:
The EDID extension structure serves as an intermediary that organizes and standardizes the wearable device specifications. Instead of the electronic device directly processing raw device data, it interacts with the structured EDID format, which simplifies the data exchange and reduces processing complexity.
3Measurement precision
If the companion device provides extended EDID data with wearable specifications, then the measurement precision of device characteristics is improved, but the loss of information transmission increases
Solution Approach 1:
The patent segments the EDID data structure into base parameters (resolution, refresh rate) and extension parameters (field of view, interpupillary distance, slice assignments). This segmentation allows the system to transmit only the necessary wearable-specific data in the extensions, reducing overall information loss while maintaining high measurement precision for critical wearable parameters.

AI summary
An electronic device includes a wireless communication device, a non-transient memory device, and one or more processors operable with the wireless communication device and the non-transient memory device. The one or more processors identify a companion device electronically in communication with the wireless communication device as being a wearable glass projection device when a received extended display identification (EDID) extension(s) from the companion device include a non-zero field of view, pixel density, and/or interpupillary distance value. The one or more processors can render content for the wearable glass projection device as a function of the non-zero field of view, pixel density, and/or interpupillary distance value, and can optionally apply a rendering adjustment to the content as a function of optical data associated with a user of the electronic device stored in the non-transient memory device.
