Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional augmented reality devices cannot interact with other devices to change the content displayed, limiting their functionality when multiple markers are present and close together.
Innovation Solution
An augmented reality system comprising multiple mobile devices with image capturing, storage, wireless communication, and processing units, which capture and match marker images to display individual or interactive composite virtual objects, and enable short-distance wireless communication to change displayed content based on device proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional augmented reality device uses a single marker with predetermined distance rules, then the device can display virtual objects based on marker arrangement, but the device cannot interact with other augmented reality devices to change the content displayed
Solution Approach 1:
The patent combines multiple mobile devices into a collaborative augmented reality system where devices communicate via wireless communication units. When multiple devices detect the same marker within a predetermined distance, they merge their capabilities to display interactive composite virtual objects, enabling content changes through device interaction while managing complexity through coordinated processing.
Solution Approach 2:
Each mobile device in the system is designed with multi-functionality, serving as both an independent augmented reality device and a collaborative node. The processing unit can independently process marker detection and also coordinate with other devices through wireless communication, allowing the same hardware to perform multiple functions based on operational context.
2Adaptability or versatility
If multiple markers are present with distance smaller than predetermined distance, then the conventional device can display meaningful arrangements, but the functionality is limited when markers are close together
Solution Approach 1:
When multiple markers are detected within predetermined distance, the system merges individual virtual objects into interactive composite virtual objects. Instead of displaying separate objects that may clutter the view, the processing unit combines them into a unified interactive display that varies based on device proximity and group identification, enabling content variability without increasing the quantity of displayed objects.
3Adaptability or versatility
If the conventional augmented reality device displays multiple virtual objects when multiple markers are present, then the device provides more content, but the device cannot dynamically change content through device interaction
Solution Approach 1:
The system implements feedback mechanisms where the processing unit continuously monitors wireless communication signals from other devices and adjusts the displayed content accordingly. When devices detect each other within predetermined distance, the feedback loop enables dynamic content changes based on group composition and device proximity, maintaining ease of operation through automatic adjustment without requiring manual user configuration.

AI summary
An augmented reality system includes a plurality of mobile devices. Each mobile device includes: an image capturing unit capturing a real image of a target marker to generate a captured image; a storage unit storing a reference image of the target marker, an individual virtual object and a plurality of interactive composite virtual objects; a wireless communication unit capable of short-distance wireless communication with another mobile device located within a predetermined range; a processing unit determining whether the captured image matches the reference image; and a display unit controlled by the processing unit to display one of the individual virtual object, the interactive composite virtual objects and the captured image.
