1Ease of operation
If traditional data transmission methods (USB, Wi-Fi, Bluetooth, NFC) are used, then data can be transmitted between terminal devices, but the user must perform cumbersome operations and the transmission direction may be incorrectly determined
Solution Approach 1:
The system automatically determines transmission direction based on device relative position and gesture recognition, eliminating the need for users to manually select send/receive roles. The devices self-identify their spatial relationship and execute transmission accordingly, making the system self-configuring and self-determining.
Solution Approach 2:
The patent replaces manual mechanical operations (button pressing, menu selection) with automatic sensing systems including magnetic sensors for position detection and gesture recognition algorithms for intent identification, substituting physical user interactions with automated electronic determination.
2Productivity
If manual transmission mode selection is used, then data transmission can be performed, but the process becomes complex and error-prone
Solution Approach 1:
The patent extracts the complex transmission mode selection process and replaces it with a simplified gesture-based control mechanism. By removing the need for users to navigate through transmission mode menus and make manual selections, the system achieves high transmission efficiency with minimal user input.
Solution Approach 2:
The system changes the control parameter from manual menu selection to gesture recognition. By detecting magnetic field changes and analyzing gesture patterns, the system determines transmission parameters automatically, reducing operational complexity while maintaining transmission efficiency.

Implementation Method 1
The first device monitors a change in magnetic induction signal strength of the first device, and when the change in the magnetic induction signal strength exceeds a preset strength change threshold, determines that the distance between the first device and the second device is less than a distance threshold
Implementation Method 2
The movement manner in which the user holds the first device may be obtained by detecting a change in acceleration of the first device, and the change in the acceleration may be detected by using a component such as a gravity sensor in the device

AI summary
A content transmission method is provided. The method may include: A first device determines that a distance between the first device and a second device is less than a distance threshold. The first device provides a user with a prompt that content transmission can be performed between the first device and the second device. The first device recognizes a gesture operation performed by the user on the first device, and determines transmission content and a transmission direction of the transmission content between the first device and the second device based on the recognized gesture operation. The first device receives the transmission content from the second device or sends the transmission content to the second device based on the determined transmission direction.
