Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-device collaboration scenarios across different operating systems, shortcut key operations on peripheral devices are not recognized and responded to, leading to reduced operating efficiency and user experience.
Innovation Solution
An event processing method and apparatus that converts shortcut key events between different operating systems by detecting events on an input device, determining the current focus device, generating event information with a mapping relationship, and transmitting it in a predefined format for recognition by the target operating system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If shortcut key operations are used on a peripheral device connected to one operating system, then the operation can be recognized and responded to by that operating system, but the shortcut key operation cannot be recognized and responded to on a device with a different operating system
Solution Approach 1:
The patent introduces an event processing apparatus that acts as an intermediary between the input device and different operating systems. This apparatus detects input events, determines the current focus device, converts event information based on mapping relationships between different operating systems, and transmits the converted events to the appropriate device. This mediator resolves the contradiction by enabling cross-operating system compatibility while maintaining reliable shortcut key recognition through systematic event conversion.
2Adaptability or versatility
If event conversion between different operating systems is implemented, then shortcut key operations can be recognized across different operating systems, but the system complexity increases
Solution Approach 1:
The event processing apparatus is designed with multi-functional capabilities to handle events from different operating systems through a unified framework. It can detect events from various input devices, determine focus devices across multiple systems, perform conversions based on mapping relationships, and transmit to different targets. This universal design reduces overall system complexity by consolidating multiple specialized components into a single multi-functional apparatus.
3Productivity
If shortcut key events are converted and transmitted between different operating systems, then operating efficiency is improved, but the processing time and system resources increase
Solution Approach 1:
The patent establishes mapping relationships between different operating systems in advance, storing the correspondence between event types and their equivalents in other systems. When an input event occurs, the event processing apparatus can quickly determine the appropriate conversion based on pre-configured mappings, rather than performing complex real-time analysis. This preliminary preparation significantly reduces the time required for event conversion and transmission, balancing productivity improvement with time efficiency.

AI summary
An event processing method and apparatus of an input device are applied to the field of electronic technology. The method includes: detecting, by a first electronic device, a first event of an input device; determining a focus device; generating event information based on an event type of the first event and a first mapping relationship when the focus device is a second electronic device, where the event information includes a key scan code and a first event type, and the first mapping relationship includes a correspondence between the key scan code and a first key code; and transmitting event information to the second electronic device, where the event information is used for converting the first event into an event under a second operating system.
