NFC Location Prompting for Hidden Vehicle Display Antennas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
NFC antennas in vehicle cockpits are often deployed inside central display screens with narrow frames, lacking obvious signs, making it difficult for users to locate them for OneHop service operations.
Innovation Solution
A method and device that automatically display prompt information on a display when a preset condition is met, guiding users to the NFC location, ensuring the user can perform OneHop services safely and effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If NFC antenna is deployed inside central display screen to save space, then device integration is improved, but user ability to locate NFC antenna is worsened
Solution Approach 1:
The patent applies visual indication methods such as displaying colored icons, animations, or highlighted areas on the display screen to indicate the NFC antenna location. The display shows graphical elements (e.g., icons, text, or visual effects) that change color or appear/disappear to guide users to the correct tapping position, resolving the contradiction by making the hidden NFC antenna visible through visual signals.
2Shape
If no obvious NFC sign is provided to maintain display aesthetics, then appearance quality is improved, but user guidance capability is worsened
Solution Approach 1:
The system performs preliminary actions by displaying visual indicators, icons, or text information before the user attempts NFC operation. The display shows guidance information in advance (such as icons indicating NFC areas, text prompts, or animated guides) so users know where to tap before they actually perform the NFC action, preventing information loss while maintaining aesthetic design.
3Ease of operation
If prompt information is always displayed to guide NFC location, then user guidance is improved, but display interference with normal use is worsened
Solution Approach 1:
The system uses periodic action by displaying prompt information only at specific moments when needed (such as when the device detects an NFC-capable device is nearby, or when the user attempts an NFC operation). The visual indicators appear temporarily and then disappear, providing guidance only during relevant periods rather than continuously, thus avoiding interference with normal display usage while still guiding NFC operations effectively.

AI summary
Embodiments of this application provide a method and a device. A method is applied to a first device, and the first device is capable of performing near field communication NFC with a second device. The method may include determining whether a preset condition is met, where the preset condition is a first condition or a second condition, the first condition is that the second device establishes a communication connection to the first device, and the second condition is that a distance between the first device and the second device is less than or equal to a first preset distance, and, when determining that the preset condition is met, displaying, on a display of the first device, prompt information indicating an NFC location.
