Automatic Screen Projection via Device Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current screen-projection solutions require manual operations to project images from a display screen of an electronic device onto a large-screen device, which is inconvenient and hinders a seamless user experience.
Innovation Solution
A display control method that enables automatic screen-projection by determining the position and association of devices within a preset range, establishing a direct connection channel, and sending data from a first device to a second device for display without manual intervention, using sensors and processors to detect and manage the connection based on predefined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operations are used to project images from a display screen to a large-screen device, then the projection process can be controlled, but the user convenience and operation simplicity deteriorate
Solution Approach 1:
The system automatically detects the first device within preset range, determines its position through sensors, establishes connection channels, and transmits data without requiring manual user operations. The projection system serves itself by autonomously completing the entire projection process from detection to display.
Solution Approach 2:
The system performs preliminary actions by pre-determining device positions, pre-establishing association relationships, and pre-setting connection channels before the actual projection is needed. This prepares the system in advance so that when projection is required, it can occur automatically without manual intervention.
2Ease of operation
If automatic screen-projection is implemented by detecting device position and establishing direct connection, then operation simplicity improves, but device complexity increases
Solution Approach 1:
The sensor system and processor are designed to perform multiple functions: detecting device positions, determining association relationships, establishing connection channels, and controlling data transmission. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The patent combines the detection function, association determination function, connection establishment function, and data transmission function into an integrated system. The sensor and processor work together as a unified system to handle the entire projection process, merging multiple functions into a coordinated workflow.
3Productivity
If direct connection channel is established between first device and second device for data transmission, then transmission efficiency improves, but connection management complexity increases
Solution Approach 1:
The system introduces an intermediary mechanism (the processor and association relationship system) that manages the direct connection between the first device and second device. This intermediary handles the complexity of connection establishment, maintenance, and termination, while the actual data transmission occurs directly between the devices for high efficiency.

AI summary
A display control method applied to a first device includes: determining a first position of the first device, when it is determined that a second device is located within a preset range of the first device and the second device is an associated device of the first device; and sending, when the first position of the first device meets a condition and based on a direct connection channel between the first device and the second device, data of the first device to the second device to display the data on the second device.
