Portable Device External Display Input Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable electronic devices lack the capability to control the display screen of external devices when mirroring or extending displays, limiting user input functionality.
Innovation Solution
A method and apparatus that detect user input events to switch between controlling the display screen of the portable electronic device and the external device, allowing the portable device to process inputs as commands for either its own screen or the external screen, using a communication unit, processor, and memory to manage the switching between modes.

Engineering Contradiction Analysis
1Area of stationary object
If the portable electronic device displays an image via an external device, then the display capability is improved, but the ability to control the external device's display screen is lost
Solution Approach 1:
The portable electronic device acts as an intermediary between the user and the external display device. It receives user inputs through its own input interfaces (touchscreen, buttons, etc.) and transmits control signals to the external device to modify its display screen, thereby enabling indirect control of the external device through the portable device as a mediator.
Solution Approach 2:
The portable electronic device is designed to perform multiple functions: it serves as both a standalone computing device and a remote control for the external display device. By integrating display output capability and control signal generation, the portable device becomes a universal tool that can both display content and control the display parameters of external devices.
2Device complexity
If the portable electronic device only provides display function via external device, then the device complexity is reduced, but the functionality for controlling external device screen is insufficient
Solution Approach 1:
The portable electronic device dynamically switches between different operational modes: when connected to an external display device, it transitions from a simple display output mode to a control mode where it can send commands to modify the external device's screen. This dynamic adaptability allows the device to maintain low complexity in normal operation while gaining enhanced functionality when needed.

AI summary
A method and an electronic device thereof for controlling a user input includes detection of a connection of the electronic device and an external display device. An application selected by a user control is executed and an execute image is provided to the external display device. Whether an event for controlling a user input occurs is detected. When the event for controlling the user input occurs, the user input is processed as an input for the selected application being displayed on the external display device.
