Key Operation Conversion for Touch Screen App Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Application programs developed for touch screens are incompatible with non-touch screen terminal units, leading to a decline in software development for these devices as developers are unwilling to create separate programs.
Innovation Solution
A conversion method and device that detects click actions on non-touch screen terminal units, acquires ID information, searches for corresponding position information in a preset profile, and generates a touch screen event at the specified position on the display screen, effectively converting key operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If application programs are developed specifically for touch screens, then the user interaction experience is improved, but the compatibility with non-touch screen terminal units deteriorates
Solution Approach 1:
The patent introduces a conversion device as an intermediary layer between the touch screen application program and the non-touch screen terminal unit. This conversion device translates touch screen operations into equivalent non-touch screen operations, allowing applications to run on both types of devices without modification. The conversion device mediates the interaction by detecting operations on the non-touch screen terminal unit and generating corresponding touch screen events that the application can understand.
2Adaptability or versatility
If developers create separate application programs for non-touch screen terminal units, then the compatibility is improved, but the development time and cost increase
Solution Approach 1:
The conversion device provides universal functionality by enabling a single touch screen application program to operate on both touch screen and non-touch screen terminal units. Instead of requiring developers to create separate applications for different device types, the conversion device makes one application universally compatible with multiple device types, eliminating the need for separate development efforts.
3Ease of operation
If touch screen technology is used exclusively, then the man machine interaction simplicity is improved, but the universality of terminal units deteriorates
Solution Approach 1:
Instead of requiring non-touch screen devices to emulate touch screen functionality, the patent inverts the approach by enabling non-touch screen devices to generate and process touch screen events through the conversion device. This allows the system to maintain the simplicity of touch screen interaction while extending universality to non-touch screen devices through the reverse conversion process.

AI summary
Provided is a conversion method for key operations on a non-touch screen terminal unit, involving the steps of: detecting a click action on a target key on the terminal unit, and acquiring the ID information of the target key; searching position information corresponding to the ID information in a preset profile according to the ID information; and, generating a touch screen event at the position indicated by the position information on the display screen of the terminal unit. With the present method, application programs developed for touch screens can run on non-touch screen terminal units compatibly, and thereby the compatibility of the terminal units is improved.
