Bluetooth AOA Screen Projection Device Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen projection methods require users to manually select a target electronic device from a list, which can be cumbersome, especially when there are many devices, as device identifiers are often complex and difficult to understand.
Innovation Solution
The method employs Bluetooth Angle of Arrival (AOA) technology to automatically detect and determine a target device's position, allowing for intuitive alignment and projection without manual selection, and adapts the content sent based on the device's capabilities to ensure accurate display or playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual selection from device list is used, then device selection is possible, but operation complexity increases and user experience deteriorates
Solution Approach 1:
The system automatically determines the target electronic device by detecting device positions and identifiers without requiring manual user selection. The first electronic device autonomously completes the device selection process by obtaining device information, determining positions, and automatically identifying the target device based on proximity or positioning data, thereby eliminating complex manual operations for users.
2Loss of information
If device identifiers are displayed in list, then device identification is possible, but user understanding becomes difficult due to complex character sequences
Solution Approach 1:
The system introduces an intermediary mechanism that translates complex device identifiers into easily understandable positional information. Instead of directly presenting users with complex character sequences, the system uses positioning technology to represent devices by their spatial relationships (e.g., direction and distance), serving as a mediator between the raw device identifiers and user comprehension.
3Extent of automation
If automatic device determination is implemented, then operation simplicity improves, but technology complexity increases due to Bluetooth AOA requirement
Solution Approach 1:
The system replaces manual mechanical selection operations with automated electronic positioning detection. Instead of requiring users to manually browse and select devices through interface operations, the system substitutes this mechanical interaction with electronic automation using Bluetooth AOA technology to automatically detect and determine target devices based on their spatial positions.

AI summary
This application provides a screen projection method and an electronic device. The method includes: detecting a position of one or more other electronic devices relative to a first electronic device by using a Bluetooth angle of arrival (AOA) technology (S1601); determining a target device from the one or more other electronic devices based on the position of the one or more other electronic devices relative to the first electronic device (S1602); detecting a screen projection operation (S1603), and sending first information to the target device in response to the screen projection operation, so that the target device displays or plays the first information (S1604). In the method, the electronic device may automatically determine a target electronic device from a plurality of electronic devices, and then project a screen on the target electronic device, to facilitate operations and improve user experience.
