POS Terminal Remote Control With Physical Button Simulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote POS terminal control systems limit operations to screen synchronization only, preventing physical navigation buttons from being activated, such as shutting down the POS terminal remotely.
Innovation Solution
A method and device that generate a two-dimensional menu based on physical navigation buttons of the POS terminal, stitching it with the screen image to create a stitched image, allowing remote control of these buttons through a second terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen synchronization is implemented between remote terminal and POS terminal, then remote viewing of POS screen is enabled, but physical navigation buttons cannot be operated remotely
Solution Approach 1:
The patent merges the POS terminal screen image with a two-dimensional menu representing physical navigation buttons into a single stitched image. This combination allows the remote terminal to simultaneously display both the POS screen content and the controllable button representations, enabling comprehensive remote operation including physical button simulation.
Solution Approach 2:
The stitched image serves as an intermediary between the POS terminal and the remote terminal. It combines visual information from the POS screen with interactive button representations, allowing the remote terminal to control POS functions without direct physical contact with the POS hardware.
2Adaptability or versatility
If only screen content is synchronized, then simple operations are limited, but comprehensive control including physical buttons is not achieved
Solution Approach 1:
The patent segments the control interface into distinct components: the POS screen image area and the two-dimensional menu area representing physical buttons. This segmentation allows each component to be independently processed and displayed, then combined into a unified stitched image that provides comprehensive control functionality.
Solution Approach 2:
The patent adds a dimensional layer by superimposing the two-dimensional menu representation of physical buttons onto the POS screen image. This creates a multi-layered interface where button control functionality is integrated alongside the original screen content, expanding operation scope without completely redesigning the display.
3Adaptability or versatility
If physical navigation buttons are integrated into remote control, then comprehensive POS control is enabled, but system complexity increases
Solution Approach 1:
The patent creates a visual copy or representation of the physical navigation buttons as a two-dimensional menu overlaid on the stitched image. This copy allows the remote terminal to interact with button functions through the display interface without requiring direct integration of physical button hardware, managing complexity while enabling comprehensive control.

AI summary
A terminal control method, an electronic device, and a storage medium are provided. The method includes: in response to receive a control request from a second terminal, and the first terminal has at least one physical navigation button, obtaining a two-dimensional menu according to the physical navigation button; obtaining a stitched image according to the two-dimensional menu and a screen image of the first terminal; and receiving operation data of the second terminal according to the stitched image, generating and responding to an instruction corresponding to the operation data.
