Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality and mixed reality near-eye displays are not lightweight, cost-effective, and have a limited virtual image field of view, with significant vergence-accommodation mismatch, making them impractical for wide usage without compromising form factor and transparency.
Innovation Solution
A mobile computing system with a wearable component that establishes wireless connections with proximal devices to receive and present location-based information through a display, optimizing the computing experience by using local storage to reduce latency and enhance connectivity, allowing for customizable and context-aware content presentation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If existing augmented reality near-eye displays are made with current technology, then they can provide visual information, but they become heavy and have limited field of view
Solution Approach 1:
The system divides the computing functionality into multiple components: a lightweight wearable display unit and separate wireless devices (smartphone, tablet, or cloud server) that perform heavy processing. This segmentation allows the near-eye display to remain lightweight while still providing access to comprehensive virtual image content through wireless connections.
Solution Approach 2:
Wireless communication acts as an intermediary between the lightweight display and external computing resources. The display unit connects via wireless protocols to smartphones, tablets, or cloud servers, which serve as intermediaries to provide processing power and content without adding physical weight to the wearable device.
2Reliability
If existing augmented reality displays use current optical configurations, then they can be manufactured, but they have significant vergence-accommodation mismatch
Solution Approach 1:
The system dynamically adjusts the focal plane of virtual images to match the user's accommodation state. By making the optical configuration adaptive rather than fixed, the system can optimize vergence-accommodation matching for different viewing conditions without requiring complex fixed optical structures that would be difficult to manufacture.
Solution Approach 2:
The system changes optical parameters such as focal distance and vergence angle based on user feedback and environmental context. By adjusting these parameters dynamically, the system achieves better vergence-accommodation matching without committing to a single complex optical design that would be hard to manufacture.
3Ease of operation
If augmented reality displays prioritize transparency and lightweight design, then they are more wearable, but they have reduced manufacturing precision and quality control
Solution Approach 1:
The patent extracts the complex manufacturing requirements from the near-eye display by moving heavy processing, storage, and content delivery functions to external devices. This allows the wearable unit to use simpler, more transparent optical elements that are easier to manufacture with high precision, while still delivering high-quality augmented reality experiences through the wireless connection to external systems.

AI summary
This disclosure describes techniques for receiving information that is wirelessly transmitted to a mobile computing system by wireless devices that are proximal to a route being travelled by the mobile computing system, and presenting at least a portion of the received information through a display of the mobile computing system. The information can be displayed according to a computing experience that is determined for a user of the mobile computing system (e.g., user-selected, inferred based on a stored schedule of the user, and so forth). Different sets of location-based information can be transmitted to the mobile computing system from different wireless devices that the mobile computing system comes into proximity with while traveling along a route. In some instances, the information can be locally stored on the wireless device(s) to reduce latency.
