Solution Overview
Problem
Current mobile communication systems face challenges in efficiently providing users with location-specific object information without overburdening cellular networks and reducing power consumption, especially in crowded areas where multiple users seek similar data simultaneously.
Innovation Solution
A wireless communication system incorporating a near field communication (NFC) reference device that stores object reference data and images, allowing a mobile device with an NFC transceiver, image sensor, and controller to recognize and overlay relevant data onto a sensed image, reducing data traffic and power usage by leveraging proximity-based communication and image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If object information is delivered through cellular networks, then users can access location-specific data, but data traffic on cellular networks increases and power consumption rises
Solution Approach 1:
The patent introduces NFC reference devices as intermediary elements deployed at physical locations containing objects of interest. These devices store object information locally and enable proximity-based data exchange, serving as mediators between the cellular network and mobile devices. This intermediary approach allows users to access location-specific information without continuously relying on cellular network data transmission, thereby reducing both data traffic and power consumption while maintaining information availability.

3Measurement precision
If NFC reference devices are deployed at multiple locations, then location-specific information accuracy improves, but device complexity and deployment cost increase
Solution Approach 1:
The patent employs a standardized template approach where NFC reference devices are deployed as replicated copies across multiple locations. Each device contains identical core functionality and data structures, storing locally relevant object information in a uniform format. This copying strategy enables consistent user experience across different locations while simplifying deployment, as the same device design and data population process can be replicated systematically without requiring complex customization at each site.

AI summary
A wireless communications system may include a near field communication (NFC) reference device configured to store object reference data for at least one object associated with a geographic location of the NFC device. The wireless communications system may also include a mobile wireless communications device that includes an NFC transceiver configured to communicate with the NFC device based upon proximity thereto, an image sensor, a display, and a controller. The controller may cooperate with the NFC transceiver, the image sensor, and the display. The controller may be configured to determine a sensed image from the image sensor. The controller may also be configured to select object reference data for the sensed image based upon communication with the NFC reference device, and display the object reference data and the sensed image on the display.
