Video Call Switching Between Communication Device and Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication devices have small screens, making it inconvenient to view multiple participants during video calls, and switching video calls between devices is complex due to the lack of portability and video call functionality in larger display devices.
Innovation Solution
A method that determines the proximity of a display device with a larger screen to a communication device, allowing automatic switching of video calls by transmitting communication information and launching network communication software to enable seamless call transfer between devices.

Engineering Contradiction Analysis
1Area of stationary object
If the user switches video call from communication device to display device, then the screen size increases and image clarity improves, but the operation process becomes complicated and time-consuming
Solution Approach 1:
The system pre-establishes wireless connection protocols and device pairing mechanisms between communication devices and display devices. When a video call is initiated, the system automatically detects available display devices in proximity and prepares the handover process in advance, so that when the user wants to switch screens, the transition can occur rapidly without manual configuration or complex operations.
2Area of stationary object
If the user manually switches video call between devices, then the call can continue on larger screen, but the switching process takes too much time
Solution Approach 1:
The system continuously monitors the proximity and connection status between communication devices and display devices during video calls. When a display device enters the predetermined distance range, the system automatically triggers the handover process. This feedback mechanism ensures that the switching occurs at the optimal moment without requiring user intervention, thereby minimizing switching time while maintaining seamless call continuity.
Solution Approach 2:
The system performs automatic device detection, connection establishment, and call transfer without requiring user intervention. The communication device autonomously identifies available display devices, initiates the handover process, and completes the transition of video call resources. This self-service capability eliminates manual operations and reduces switching time to nearly instantaneous.
3Area of stationary object
If display device is used for video call, then image quality improves, but the display device must be portable and have video call function
Solution Approach 1:
The system creates a universal communication platform where display devices without native video call functions can still participate in video calls through wireless connection to communication devices. The communication device acts as a bridge, relaying video call data between the network and the display device. This multi-functional approach allows any display device with a screen to serve as a video call interface, expanding compatibility beyond devices with built-in communication capabilities.

AI summary
A method for switching a call with video or at least one image between a first communication device and a display device is disclosed. The method includes the first communication device determining whether the display device is within a predetermined distance from the first communication device; if the display device is within the predetermined distance from the first communication device, the first communication device obtaining functional information from the display device; the first communication device transmitting communication information corresponding to a second communication device to the display device; and the display device launching network communication software and making a first call to the second communication device according to the communication information.
