Synchronized Touch Device Operation via USB Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile touch devices have limited screen size and connectivity issues with electronic facility hosts, making it difficult for users, especially the elderly and visually impaired, to perform complex operations like file editing and transfer, and existing solutions require hardware modifications or complex interfaces.
Innovation Solution
A synchronized operation system that connects a mobile touch device to an electronic facility host via a USB interface, allowing synchronized image displaying, keyboard operation, and cursor control, enabling users to perform touch operations on the host's display and transmit results back to the mobile device without modifying hardware, using cabled or wireless connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If the screen size of mobile touch device is reduced to make it compact and light-weighted, then portability is improved, but the area of screen for displaying images, texts, or virtual keyboard is limited and reading becomes difficult
Solution Approach 1:
The patent merges the mobile touch device's display with the electronic facility host's display system. The touch screen images are transmitted to and displayed on the host's larger display device, effectively combining the portable input device with a stationary large-area display to overcome the screen size limitation while maintaining device portability.
Solution Approach 2:
The patent extends the display area from the two-dimensional limited touch screen to the larger two-dimensional host display device. By transmitting touch screen images to the host system, the effective display area is expanded without increasing the physical size or weight of the mobile device itself.
2Adaptability or versatility
If conventional file transfer connection is used between mobile touch device and computer host, then connectivity is established, but the operation process becomes complicated requiring complex man-machine interface and screen operations
Solution Approach 1:
The patent implements self-service automation where the system automatically detects the connection state between mobile device and host, automatically transmits touch screen images to the host display, and automatically enables synchronized operation. This eliminates the need for users to manually configure complex interfaces or screens, making file transfer operations simple and intuitive.
Solution Approach 2:
The patent performs preliminary actions by pre-establishing the image transmission and synchronized operation framework before file transfer operations begin. The system proactively configures the display synchronization and operation mapping in advance, so when users need to transfer files, the complex setup is already complete and only simple operations are required.
3Loss of information
If user operates touch screen of mobile touch device to identify operation results, then operation feedback is obtained, but the user cannot watch the progress of transfer or monitor operations on the touch screen simultaneously
Solution Approach 1:
The patent merges the operation feedback display with the host system's larger display device. Both the touch screen images and the operation results are displayed simultaneously on the host display, allowing users to monitor file transfer progress and operation results while maintaining the ability to interact with the mobile device's touch screen.
Solution Approach 2:
The patent creates an additional display dimension by transmitting touch screen images to the host system's display. This provides a parallel viewing area where users can simultaneously see operation progress and results without blocking the interaction with the mobile device's touch screen interface.
4Ease of operation
If existing solutions are implemented to enable synchronized operation, then operation functionality is improved, but hardware structure modification is required which reduces portability and industrial utilization
Solution Approach 1:
The patent uses software-based copying of the touch screen display output to the host system's display device. Instead of modifying hardware structures, the solution creates a software layer that captures and transmits the touch screen images and operation signals, enabling synchronized operation through firmware or software implementation that maintains hardware compatibility.
Solution Approach 2:
The patent creates a universal solution that works with existing mobile touch devices and electronic facility hosts without requiring hardware modifications. The synchronized operation framework is designed to be compatible with standard USB connections and common display interfaces, making it applicable to various device types and maintaining industrial utilization.

AI summary
A system and method for synchronized operation of touch device has a mobile touch device which includes a USB transmission interface and a touch screen and an electronic facility host. The USB transmission interface connects to the USB interface of the electronic facility host and synchronizes image displaying, synchronized keyboard operation, and cursor operation so an image of the touch screen of the mobile touch device synchronously opens an image displaying zone on the display device of the electronic facility host and the keyboard and the cursor device directly simulate and synchronously operate touch display operation functions of the mobile touch device in the image displaying zone, operation of file duplication, writing, deletion, and edition between the facility host and the mobile touch device with at least one window of the operation platform of the electronic facility host.
