Multi-Touch HMI Trend Graph Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Human-Machine Interfaces (HMIs) in industrial environments require users to operate cumbersome input devices like keyboards and mice to manipulate graphical displays of trend data, making it inefficient for users to quickly alter or manipulate these displays.
Innovation Solution
A multi-touch enabled HMI system that allows simultaneous user inputs on a surface to process and display changes in trend data, enabling users to zoom, expand, compress, or remove sections of graphical representations directly on a touch screen interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional input devices (keyboard and mouse) are used to manipulate graphical displays, then the HMI system can be operated, but the operation becomes slow and inefficient
Solution Approach 1:
The patent replaces traditional mechanical input devices (keyboard and mouse) with a multi-touch sensitive display surface that directly responds to finger touches. This substitution eliminates the need for intermediate mechanical devices, allowing users to manipulate graphical displays directly with their fingers, thereby increasing operation speed and reducing cumbersomeness
Solution Approach 2:
The multi-touch sensitive display surface acts as an intermediary between the user and the HMI system. It captures multiple simultaneous touch inputs and translates them into corresponding manipulations of graphical displays, enabling intuitive and efficient interaction without requiring traditional input devices
2Productivity
If single touch input is used on the display surface, then the interface is simple to operate, but the capability to manipulate trend graphs efficiently is limited
Solution Approach 1:
The system dynamically adapts its input processing capability based on the number of touches detected. When multiple touches are detected, the system activates enhanced manipulation modes that allow simultaneous control of multiple graph elements or parameters, thereby increasing operational efficiency without requiring permanent complex hardware
Solution Approach 2:
The patent adds a temporal dimension to touch input processing by detecting and processing multiple touches that occur simultaneously or in rapid succession. This allows the system to interpret sequences of touches as composite commands, enabling complex graph manipulations through simple sequential finger movements

AI summary
A Human-Machine Interface (HMI) system comprises a machine interface, a processing system, and a user interface. The machine interface receives operational data associated with an operation of a machine. The processing system processes the operational data associated with the operation of the machine to determine a trend in the operational data. The user interface displays a graphical representation of the trend, and receives a first user input and a second user input simultaneously on a surface of the user interface. The processing system processes the first user input and the second user input to determine a change in the trend. The user interface displays a graphical representation of the change in the trend.
