The electronic device incorporates an electromagnetic inductive circuit and a touch screen panel, along with a processor, to identify the position of a wearable device on the user's body and track its movement relative to the display, allowing for dynamic screen changes based on these interactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the electronic device uses traditional touch screen detection methods, then the device can detect basic touch positions, but it cannot accurately identify the position relationship between the display and the user's body for dynamic screen adjustments
Solution Approach 1:
The patent combines electromagnetic inductive circuit detection with touch screen panel detection into a unified detection system. The electromagnetic inductive circuit is integrated within the display structure, allowing simultaneous detection of body contact position and wearable device position through the same physical space, thereby improving measurement precision without proportionally increasing device complexity
Solution Approach 2:
The electromagnetic inductive circuit acts as an intermediary detection layer between the touch screen panel and the user's body. It detects changes in electromagnetic induction caused by the proximity or contact of conductive materials (such as wearable devices on the body), enabling indirect detection of body position relationships that cannot be directly measured by traditional touch screens
2Ease of operation
If the electronic device implements dynamic screen changes based on body position, then user interaction responsiveness is enhanced, but the system requires complex real-time position tracking and screen adjustment mechanisms
Solution Approach 1:
The system implements a feedback loop where the electromagnetic inductive circuit continuously monitors the position relationship between the display and the user's body, and the processor automatically adjusts screen parameters (such as brightness, content, or orientation) based on the detected position changes. This closed-loop feedback mechanism enables responsive user interaction while automating the complexity of screen adjustment decisions
Solution Approach 2:
The patent enables dynamic screen characteristics that automatically adapt to the detected body position relationship. The screen transitions from a static display to a dynamic one that changes its properties in real-time based on user interaction, allowing the system to respond to different usage scenarios without requiring manual configuration or complex mechanical adjustments

AI summary
According to an embodiment, an electronic device includes a display including an electromagnetic inductive circuit and a touch screen panel, memory storing instructions, and a processor. The instructions, when being executed by the processor, cause the electronic device to identify a first position on the display, where the portion of the body of a user is contacted, and identify a second position of a wearable device worn on the portion of the body, with respect to the display. The instructions, when being executed by the processor, cause the electronic device to identify a position relationship between the display and the portion of the body. The instructions, when being executed by the processor, cause the electronic device to identify that a position of the portion of the body which is in contact with the display is changed from the first position to a third position. The instructions, when being executed by the processor, cause the electronic device to change a screen displayed on the display.
