Trigger Event Mapping for Cross-Device Projection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When content is projected from a source electronic device to a target electronic device, the target device cannot recognize or process input operations not supported by the source device, leading to inconvenience for users.
Innovation Solution
A control method and apparatus that monitors and maps trigger events from the target device to recognizable information, allowing the source device to transmit this information to the target device to perform intended operations, thereby enabling recognition and processing of unsupported input operations.

If content is projected from source electronic device to target electronic device, then display capability is improved, but operation compatibility deteriorates
Solution Approach 1:
The patent introduces an intermediary mapping mechanism that translates operations from the target device into equivalent operations the source device can recognize. When the source device projects content to the target device, the target device's operations are intercepted and mapped to corresponding source device operations through a translation layer, enabling compatibility without requiring the source device to natively support target device operation modes.
Solution Approach 2:
The patent changes the parameter representation of operations by mapping trigger events from the target device to equivalent trigger events the source device can process. This involves transforming operation parameters (such as keyboard shortcuts, touch gestures, or command structures) into a format that the source device's operating system can recognize and execute, thereby resolving the compatibility issue while maintaining display projection functionality.
2Ease of operation
If target electronic device uses native operations, then operation convenience is improved, but source device recognition capability deteriorates
Solution Approach 1:
The mapping mechanism serves as an intermediary that allows users to continue using familiar target device operations while enabling the source device to recognize and process these operations. The translation layer converts target device-specific operations into source device-compatible commands, maintaining both user convenience and system recognition capability simultaneously.
Solution Approach 2:
Instead of requiring the source device to adapt to target device operations, the patent inverts the approach by having the target device operations translated into source device language. This reversal allows the source device to maintain its original operation recognition capabilities while still responding to target device input methods, solving the contradiction between convenience and recognition.

AI summary
A control method and a control apparatus are provided. The method includes: monitoring whether a first trigger event is generated when a first electronic device outputs, based on display data, a first display content via a first display unit coupling the first electronic device, wherein the display data is transmitted to the first electronic device by a second electronic device and corresponds to a second display content of the second electronic device, wherein the second display content is same as the first display content; mapping the first trigger event to first information that can be recognized by the second electronic device, if it is detected that the first trigger event is generated; and transmitting the first information to the second electronic device, to instruct the second electronic device to perform a first operation. An electronic device is further provided.
