Product quality has become synonymous with customer satisfaction and competitive differentiation in this age of innovation-driven exponential growth. Product quality is not restricted to software performance; it applies to all products with human-machine interfaces (HMI).
AI-powered test automation is changing how manufacturers and engineers improve product quality for various HMI-driven products, including mobile devices, car infotainment systems, medical devices, smart devices, consumer electronics and flight cockpits.
This blog discusses how AI-powered test automation can improve product quality by maintaining consistency, efficiency, and a better user experience across many industries.
What Is AI-Powered Test Automation?
AI-powered test automation employs machine learning algorithms and advanced analytics to conduct tests, recognize patterns, foresee issues, and fine-tune testing approaches. While traditional test automation is based on scripted and scenario-driven inputs, AI-based systems adapt in real-time to changes in the product and development driven by actual data.
In the case of HMI-driven products, AI-powered test automation observes user interactions with the interface, identifies potential failure points, and anticipates possible misunderstandings or failures. Thus, engineers can effectively deal with problems moreover AI & LLM can speed up the process of test case generation.
Why Product Quality Matters for HMI Systems?
Human-machine interfaces (HMI) are the intermediaries between humans and machines. Performing quality tests on HMI-driven products is crucial as these products are functional and interact directly with the user.
Poorly developed HMI products can result in product recalls, accidents, or dissatisfaction among users, especially when deployed in safety-sensitive applications such as automotive systems, medical devices, or aircraft cockpits. If a product’s quality goes bad in these scenarios, the consequences range from mere inconvenience to serious hazard.
AI integration in testing the quality of HMI products has transformed a cumbersome process into a well-structured and automated process that maintains quality benchmarks.
For instance, SGBI’s robotic automation technology helped a leading player in the energy sector test a massive number (4,500) of smart meters. The robotic automated solution accurately performed different test actions, like single- and multi-button pressing, meter reading using high-resolution cameras, and toggling switches. This solution reduced the testing time by 95% and decreased operational costs by 70%.
Key Benefits of AI-Driven Test Automation for HMI Products
AI-driven test automation provides unparalleled accuracy, efficiency, and scalability in testing HMI products. Here are some more benefits of AI-driven test automation for HMI products:
1. Improved Accuracy and Precision
AI-driven test automation ensures consistency in accuracy and minimizes human error to provide more accurate test cases. Products that feature HMI have complex user interactions, and manual testing for each scenario leaves a wide gap for undiscovered bugs or inconsistencies. AI-based systems can find those flaws that are often overlooked and enhance overall product quality with increased fidelity to the actual user experience.
The Quaco Robots are aided by an AI vision validation system. Equipped with multiple cameras, these robots constantly monitor and verify each action, preventing errors and complications.
2. Efficiency and Scalability
AI-enabled testing scales naturally with increasing complexity, which is why it is particularly useful for multi-component systems. Once a test framework is set up, AI executes repetitive tests, observes the output, and optimizes the approach for maximum test coverage with minimal human involvement to guarantee faster releases with consistent quality.
For instance, SGBI’s Quaco Studio AI can generate complex test scenarios without writing a single line of code. It generates test cases based on your requirements and accelerates the testing process.
3. Enhanced Predictive Maintenance
Predictive maintenance is essential for HMI products where reliability and safety are paramount. AI algorithms analyze data from previous test results for predictions on where points of failure may occur. This enables manufacturers to solve problems before they surface in the final product. Such proactive testing helps avert major safety risks like automotive or medical devices.
4. Reduced Testing Costs
AI-powered automation optimizes resources by conducting all the complex, high-volume testing in a fraction of the time that manual processes would take. This helps manufacturers save on post-release bug fixes or recall costs by detecting and correcting issues early. Moreover, AI automation provides significant cost savings for devices such as smartphones or wearables requiring extensive testing in multiple environments.
For instance, Tesla recalled 130,000 vehicles due to touchscreen issues, which led to an average additional cost of $12 million. While the manual testing processes are slow and error-prone, robotic-aided automated infotainment testing provides a more robust and efficient approach. For instance: SGBI’s Quaco Pro D with Quaco Studio AI revolutionizes test case creation and assists in testing user interactions comprehensively.
How to Implement AI-Powered Test Automation for HMI Product Quality?
AI-powered testing of HMI products ensures unmatched quality and reliability, meeting the highest standards in the industry. Here’s how to implement AI-powered test automation for HMI product quality:
1. Define Clear Quality Objectives
Start by defining the quality metrics relevant to your HMI product. Whether it’s latency, responsiveness, or interaction accuracy, having clear objectives will help guide your AI model in understanding what is related to a “pass” or “fail” outcome.
2. Select Appropriate AI Models and Tools
Choose an AI-powered test automation tool that fits your product’s unique needs. Some features to consider are machine learning capabilities, predictive analytics, and adaptability to changing user interactions. Well-known options include TensorFlow, Selenium with AI plugins, and custom models for specific devices. However, if you are interested in end-to-end automated testing, then robotic-aided testing, like Quaco Robotic Platform, can help. These robotic testing platforms can work 24/7 and can test the HMI products for over 8760 hours annually.
3. Train AI Models on Real-World Scenarios
The best AI-enabled testing solutions take advantage of the real usage data. When you train your model on real-world interactions, you ensure it learns to adapt to a wider variety of use cases. This minimizes the possibility of unusual bugs appearing long after the product goes live.
4. Conduct Continuous Testing and Refinement
HMI products must be updated continuously due to changes in user interaction and system updates. Implement continuous testing as part of the development process so that product iterations will match or surpass the quality standard. This is critical for products intended for highly regulated industries, like automotive or medical. SGBI’s Quaco Studio gets seamlessly integrated into your existing pipelines to help you adapt the CI/CD approach. This enables automated testing, which leads to quicker feedback loops and accelerated time-to-market.
5. Implement Predictive Maintenance Measures
Leverage the predictive capabilities of AI to pinpoint potential failure hotspots and proactively address them before they impact the end-user experience. Early identification of such risks enables your team to make better decisions regarding changes in the interface or underlying components for improved durability and reliability.
The Quaco Studio AI provides detailed analytics and reports on performance metrics. The platform can identify bottlenecks and suggest actionable recommendations to optimize the testing process.
