Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems on mobile platforms are limited in providing a fully immersive three-dimensional experience due to inaccurate location-based services and the need for stationary digital cameras as reference points.
Innovation Solution
A system and method that combines self-position sensing on mobile computing platforms with identification tags to trigger actions based on physical location and geolocational data, enabling the display of graphical objects, auditory cues, and tactile feedback, even when the user is in motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If location-based services are used to trigger actions in augmented reality, then the system can provide location-specific content, but the location accuracy is grossly inaccurate
Solution Approach 1:
The patent combines GPS location data with visual tag recognition to trigger actions. The system uses both geographic coordinates and visual identification of physical tags (such as QR codes or barcodes) at specific locations to determine when to execute augmented reality actions, thereby compensating for GPS inaccuracy with precise visual tag detection.
Solution Approach 2:
Physical tags placed at specific locations serve as intermediaries between the mobile device and the augmented reality content. These tags act as reliable triggers that bridge the gap between approximate GPS location and precise content delivery, ensuring actions are triggered accurately regardless of GPS precision limitations.
2Adaptability or versatility
If stationary digital cameras are used as reference points for augmented reality, then location-based actions can be triggered, but the system requires stationary reference points and cannot support mobile users
Solution Approach 1:
The patent transitions from stationary reference points to mobile-capable augmented reality by using mobile devices with cameras and GPS receivers. The system dynamically adapts to user movement by continuously tracking location and detecting tags in real-time, enabling augmented reality experiences while walking or moving through physical spaces.
Solution Approach 2:
The mobile device serves multiple functions: it acts as the camera for tag detection, the GPS receiver for location tracking, the processing unit for matching location and tag data, and the display device for presenting augmented reality content. This multi-functionality eliminates the need for separate stationary reference equipment.
3Measurement precision
If only GPS location data is used for triggering actions, then the system is simple to operate, but the location accuracy is grossly inaccurate
Solution Approach 1:
The system merges GPS location data with visual tag recognition technology. The mobile device captures images of physical tags at locations, processes these images to identify tag content, and combines this visual information with GPS coordinates to accurately determine when the user is at a specific location for triggering augmented reality actions.
Data Source
AI summary
A computer-implemented system and method for providing a virtual object based on physical location and tagging are provided. A set of virtual objects are maintained in a database on a mobile computing device. Each virtual object includes an action associated with an identifier and coordinates for one or more physical locations. A physical location of the mobile computing device is tracked and an identification tag within range of the mobile computing device is identified. The mobile computing device's physical location and the identification tag are respectively evaluated against the coordinates and the identifiers for the virtual objects in the database. For each of the coordinates and identifiers matched to the physical location and the identification tag, the action associated with the correspondingly matched virtual object is performed using the mobile computing device.
