Portable Terminal Screen Switching via Positional Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for portable terminals fail to easily change screens from a portable terminal to an operating panel of another apparatus, making it cumbersome to use the portable terminal as a remote operating panel, especially when the user needs to extend the screen or change the display orientation.
Innovation Solution
A portable terminal equipped with a display unit, operating unit, detecting unit, and display changing unit that automatically changes the screen when the terminal is positioned correctly relative to the other apparatus, allowing the portable terminal to function as a remote operating panel by detecting proximity, orientation, and wireless communication capabilities.

Engineering Contradiction Analysis
1Ease of operation
If a user presses a specific operating button to change the screen, then the screen can be changed from a portable terminal screen to an operating panel screen, but the operation becomes troublesome and complex
Solution Approach 1:
The system performs preliminary detection of the terminal's position and orientation relative to the operating panel before the user needs to change screens. When the terminal is brought into the correct positional relationship with the operating panel, the system automatically detects this state and triggers the screen change without requiring the user to press any buttons, thus simplifying the operation.
Solution Approach 2:
The system uses the terminal's own detection capabilities (position and orientation detection) to automatically determine when a screen change is needed. The terminal self-services by monitoring its own state and autonomously initiating the screen change process when the predetermined positional relationship with the operating panel is detected, eliminating the need for manual button pressing.
2Extent of automation
If the terminal is positioned close to the operating panel, then automatic screen changing can be enabled, but the system needs to detect position and orientation accurately
Solution Approach 1:
The system introduces a camera as an intermediary detection device to capture images of the operating panel from the terminal's perspective. By analyzing the captured images, the system can determine the terminal's position and orientation relative to the operating panel without requiring direct complex sensing. The camera serves as a mediator that translates physical spatial relationships into detectable image data that can be processed to determine positional relationships.

AI summary
A portable terminal includes: a display unit; an operating unit; a detecting unit configured to detect a position of the terminal; and a display changing unit configured to change a screen displayed on the display unit of the terminal to a screen displayed on an operating panel of a predetermined other apparatus, when the display changing unit detects that the position of the terminal detected by the detecting unit and a position of the predetermined other apparatus have a predetermined positional relationship.
