Wireless Pointer Switching via Display Changeover Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In computer systems that use Bluetooth communications, external input devices like mice and keyboards require repetitive processes of separation, recognition, and installation when switching between connected devices, leading to inefficiencies in device control and user experience.
Innovation Solution
A computer system and control method that utilize a display unit, a wireless communications module, and a pointing processing unit to allow a single external input device to control multiple devices without repeated recognition and installation processes, by setting up changeover areas on the display and converting input signals to enable seamless device switching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single external input device is used to control multiple computers, then device versatility is improved, but device complexity increases due to the need for multiple connection interfaces and switching mechanisms
Solution Approach 1:
The external input device is designed with multiple connection interfaces (first connection interface and second connection interface) that enable it to connect to different computers (first computer and second computer). This multi-functionality allows a single device to serve multiple purposes and control multiple systems, directly improving device versatility while managing complexity through standardized interface design
2Adaptability or versatility
If the external input device switches between multiple computers, then adaptability is improved, but operation complexity increases due to repetitive recognition and installation processes
Solution Approach 1:
The system performs preliminary recognition and installation of the external input device when it first connects to a computer. The computer stores recognition information about the device, so when the device switches between computers, the newly connected computer can quickly retrieve this pre-stored information rather than performing full recognition and installation procedures each time, significantly reducing switching operation complexity
Solution Approach 2:
The system implements a feedback mechanism where recognition information about the external input device is stored by the computer after initial connection. This stored information is then fed back when the device reconnects or switches, allowing the computer to automatically retrieve and use the previously stored recognition data, eliminating the need for repetitive manual configuration and simplifying the switching process
3Reliability
If recognition and installation processes are repeated for each computer connection, then connection reliability is improved, but time consumption increases
Solution Approach 1:
The computer performs recognition and installation of the external input device in advance when it first connects, storing the recognition information for future use. This preliminary action ensures that when the device switches between computers, the newly connected computer can quickly retrieve the pre-stored recognition information, maintaining connection reliability while dramatically reducing the time required for switching operations
Solution Approach 2:
Instead of discarding recognition information when the external input device switches computers, the system recovers and reuses this information. The recognition data stored by the first computer is retrieved by the second computer, eliminating the need to perform complete recognition and installation procedures again, thus reducing switching time while maintaining reliable connections

AI summary
A computer system including a display unit to display a display area of the computer system, a wireless communications module to interface with at least one external device, a pointing processing unit to move a pointer indicated on the display unit in correspondence to a first radio signal input through the wireless communications module, and a controller which controls the wireless communications module to output a second radio signal, which corresponds to the first radio signal, to the external device when the pointer points to a changeover area of the display area of the display unit for a predetermined time.
