Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for accessing supplemental information related to visual media and controlling devices are cumbersome, often requiring separate codes or tags that interfere with aesthetics and are inconvenient to install due to wired connections or power requirements.
Innovation Solution
A system using near-field communication (NFC) position devices arranged in an array behind visual media, allowing a computing device to obtain position information and transmit it to a networked device to retrieve supplemental information or control parameters, eliminating the need for separate codes or tags and enabling wireless, location-independent control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate codes or tags are used to access supplemental information, then information access is enabled, but visual aesthetics are interfered with and installation becomes cumbersome
Solution Approach 1:
The patent merges the position device functionality directly into the visual media itself. The visual media is divided into multiple portions, each associated with a position device that contains NFC circuitry. This integration eliminates the need for separate codes or tags, as the visual media becomes both the display element and the positioning element, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The visual media serves multiple functions simultaneously: it displays visual content and also contains embedded position devices with NFC circuitry for supplemental information access. This multi-functionality eliminates the need for separate components, reducing installation complexity while maintaining ease of information access.
2Ease of operation
If separate codes or tags are used for control, then device control is enabled, but wired connections and power requirements make installation inconvenient
Solution Approach 1:
The patent replaces mechanical/wired control systems with NFC-based wireless communication. The position devices contain NFC circuitry that enables wireless data transmission and device control without physical connections. This substitution eliminates the need for wired connections and power sources, making installation convenient while maintaining ease of device control.
Solution Approach 2:
The position devices are designed to be self-powered through NFC energy harvesting or passive operation, eliminating the need for external power sources. The visual media portions themselves serve as the control interface, requiring no additional installation infrastructure, thus improving ease of manufacture and installation convenience.
3Adaptability or versatility
If NFC position devices are integrated into visual media, then wireless control and information access are enabled, but the system complexity increases
Solution Approach 1:
The patent divides the visual media into multiple discrete portions, each with its own integrated position device containing NFC circuitry. This segmentation allows each portion to be independently configured and controlled, enabling wireless control capability while managing system complexity through modular design. Each segment can be processed and managed separately, reducing overall system complexity.

AI summary
In general, techniques and systems for retrieving supplemental information associated with visual media are described. In one example, a method includes obtaining, by a computing device, position information from a position device using near-field communication (NFC), wherein the position information identifies a position of the position device in relation to a portion of visual media associated with the position device. The method may also include receiving, by the computing device, supplemental information that is provided by a networked device based at least in part on the position information, wherein the supplemental information comprises additional information related to the portion of the visual media. In some examples, the position device is included within an array of position devices mounted behind the visual media.
