Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Near-Eye Display devices face challenges in managing display resources efficiently, leading to significant latency due to the need to transfer entire resources over low bandwidth connections like Bluetooth or BLE.
Innovation Solution
A computing device and Near-Eye Display device system that optimizes the management of display resources by sending a layout with graphical commands to the Near-Eye Display device, allowing it to save and display resources with minimal latency, even over low bandwidth connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If entire display resources (e.g., images) are transferred from computing device to connected glasses when needed, then the display can be executed, but significant latency occurs due to low bandwidth connection
Solution Approach 1:
The patent segments the display resource into two parts: a compact layout description (stored in the glasses) and the actual display content (transferred only when needed). This segmentation allows the system to avoid transferring entire large resources, reducing latency while maintaining display functionality.
Solution Approach 2:
The patent implements preliminary action by pre-storing layout descriptions and command structures in the connected glasses before actual display is needed. This allows the glasses to be ready for quick execution, reducing the time required when display is actually triggered.
2Weight of moving object
If connected glasses are equipped with minimal computing and storage capabilities, then the glasses become lighter and more convenient, but the ability to manage display resources efficiently is reduced
Solution Approach 1:
The patent extracts the heavy computational and storage functions from the connected glasses and relocates them to the external computing device. The glasses only retain minimal components for receiving and executing display commands, achieving weight reduction while maintaining functionality.
Solution Approach 2:
The patent introduces a communication interface as an intermediary between the external computing device and the connected glasses. This intermediary handles the complex data exchange and command transmission, allowing the glasses to remain simple while still managing display resources efficiently through external computing support.
3Reliability
If display resources are transferred over low bandwidth connections (Bluetooth/BLE), then the connection is established, but significant latency occurs
Solution Approach 1:
The patent extracts only the essential layout description and command information from the full display resource, transferring only this condensed data over the low bandwidth connection. This minimizes the data volume transmitted, reducing transfer time while maintaining connection reliability.
Solution Approach 2:
The patent uses a reference copy approach where the layout description acts as a pointer or reference to the actual display content stored locally in the glasses. This allows the system to transfer minimal data (the reference) rather than the entire resource, significantly reducing transfer time over low bandwidth connections.
