Custom Development Example of Human-Machine Interface Components

In today's digital age, the customization and development of Human Machine Interfaces (HMIs) are crucial for enhancing user experience, meeting specific business requirements, and enabling innovative functionalities. The following is a case study detailing the process of customizing a particular HMI component to demonstrate practical applications of this approach.

I. Project Background

A medical device manufacturer plans to launch a brand new smart monitor, which needs to display real-time vital signs data of patients and allows healthcare professionals to set parameters and manage records through the interface. To achieve these functions, the manufacturer has decided to customize the development of human-machine interface components.

II. Demand Analysis

During the requirement analysis phase, the development team engaged in in-depth communication with engineers from medical device manufacturers and healthcare professionals, clarifying the following requirements:

Display real-time vital signs data of patients, including heart rate, blood pressure, and oxygen saturation.

Provide a clear and easy-to-understand graphical interface that enables healthcare professionals to quickly identify and understand data.

Supports parameter setting function, allowing medical staff to adjust the working parameters of the monitor according to the specific conditions of patients.

Provides record management functions, including viewing historical data, exporting reports, etc.

III. Design Phase

During the design phase, the development team designed the following interface components based on the results of the requirements analysis:

Data Display Component: This component is responsible for real-time display of patients' vital signs data. By designing clear charts and numerical displays, medical staff can quickly understand the patient's health status. At the same time, this component also supports data refresh and zoom functions to meet different viewing needs in various scenarios.

Parameter Setting Component: This component enables healthcare professionals to adjust the working parameters of the monitor according to the specific conditions of patients. By designing intuitive interactive elements such as sliders, switches, and input boxes, this component allows healthcare professionals to easily complete parameter setting operations. In addition, it provides parameter saving and restoring functions, facilitating quick adjustments of parameters when switching between different patients.

Record Management Component: This component is responsible for viewing historical data and exporting reports. By designing a clear timeline and filtering conditions, medical professionals can quickly locate the data they need to view. At the same time, this component also supports multiple data export formats (such as PDF, CSV, etc.), making it convenient for medical professionals to use the data for subsequent analysis and report creation.

IV. Development Implementation

During the development implementation phase, the development team uses front-end frameworks (such as React, Vue, etc.) and back-end technology stacks (such as Node.js, databases, etc.) to build interface components. They follow modular and component-based development principles, encapsulating each interface component into an independent module so that it can be reused and extended in subsequent development and maintenance processes.

During the development process, the development team also focused on communicating and collaborating with engineers from medical device manufacturers and healthcare professionals. They regularly held review meetings to evaluate and improve the functionality, performance, and user experience of interface components. At the same time, they actively collected user feedback and demand changes, promptly adjusting the development plan and design scheme.

V. Testing and Optimization

After the development was completed, the development team conducted a comprehensive testing and optimization of the interface components. They simulated various scenarios of user operations and data input to ensure that the interface components could run normally and meet user needs. At the same time, they also used automated testing tools to perform performance tests and stability tests on the interface components to ensure that they could operate stably in various environments.

The issues and defects discovered during the testing process were promptly repaired and improved. The development team also further optimized and refined the interface components based on user feedback and demand changes. For example, they optimized the chart display effect and interactive experience of the data presentation component; added custom options and save-and-restore functions for the parameter setting component; and improved the data export format and filtering conditions of the record management component, etc.

VI.De Deploy and Go Live

After testing and optimization, the interface component was successfully deployed in the smart monitor and went live for use. Medical staff can use this interface component to view patients' vital signs data in real-time, perform parameter settings, and manage records. The customized development of this interface component not only enhances user experience and satisfaction but also improves the intelligence level and market competitiveness of medical equipment.
