NFC Controller Displaying Proximity Icons for Contactless Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complications in interacting with wireless devices due to the need for precise proximity in short range wireless communication, such as Near Field Communication (NFC), as they must manually determine the correct location on a display device for swiping their NFC-enabled devices without visual cues.
Innovation Solution
A system and method that utilize a near field communication controller module to access location information of a short range wireless device and display a contactless user interface icon on the display device's viewing surface, guiding users to the correct location for successful communication, enabling intuitive interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If short range wireless communication is used for automatic connections, then connectivity speed is improved, but user interaction becomes complicated due to lack of visual cues for device placement
Solution Approach 1:
The patent introduces an intermediary visual indicator (light-emitting element) that mediates between the wireless communication device and the user. This indicator provides visual feedback about the correct placement location, making the interaction intuitive without slowing down the automatic connection process
Solution Approach 2:
The patent uses color changes or light emission from an indicator element to communicate device location information to the user. The visual indicator changes state (e.g., illuminates or changes color) to guide users to the correct swiping location, improving ease of operation while maintaining fast automatic connectivity
2Device complexity
If manual determination of swiping location is required, then device complexity is reduced, but measurement precision of device location is insufficient
Solution Approach 1:
The system performs self-service by automatically determining and indicating the correct device location through the visual indicator. The display device autonomously provides location guidance without requiring complex user judgment, achieving precise device placement indication while keeping the overall system relatively simple
3Ease of operation
If contactless user interface icon is displayed proximate to short range wireless device, then ease of operation is improved, but device complexity increases due to additional display control mechanisms
Solution Approach 1:
The patent merges the visual indicator function with the existing display device infrastructure. The contactless user interface icon is integrated into the display screen, combining multiple functions (display, indication, guidance) into a single unified interface, improving ease of operation without proportionally increasing device complexity
