Advancing Game Controller Quality through High-Precision Automated Testing

Project Highlights

• Proprietary calibration algorithms and ASF (Automatic Sensory Feedback) tactile testing module

• Full data integration with SCADA for complete traceability and zero manual intervention

• Modular ASF platform enabling one automated line to test multiple controller models

Overview

In the competitive gaming hardware space, controller precision and tactile consistency are key factors shaping user experience. For this global brand’s next-generation controller, achieving uniform quality across worldwide markets required a testing solution far beyond the capabilities of traditional manual methods. High-volume production demanded greater reliability, stability, and efficiency.

Solution

Building on extensive experience in consumer electronics assembly and testing, Primax engineered a fully automated test line dedicated to game controller verification.

The system incorporates:

• High-precision force-sensing modules

• Dedicated joystick angular-deviation measurement structures

• High-frequency response monitoring systems

These technologies simulate real gameplay interactions and deliver comprehensive testing for joystick behavior, D-pad response, and all function buttons—evaluating tactile consistency, positional accuracy, and action feedback with high repeatability.

Multi-Model Testing Challenge

A core requirement was the ability for a single line to support multiple controller models. This included:

• Automatic recognition of fixture types

• Automatic adjustment of test parameters

• Rapid station and probe changeovers

Primax addressed this with the modular ASF Testing Platform, enabling automated mechanical switching and test configuration. Complemented by a self-developed data acquisition and analytics system, every button’s force curve and feedback profile is captured, classified, visualized, and stored for downstream quality analysis.

Results

After implementation:

• Automation rate exceeded 95%

• Throughput increased by 38%

• Labor input was significantly reduced

• Full compliance with customer quality and operational requirements was achieved

This solution successfully eliminated the bottlenecks of manual testing and ensured consistent, high-precision performance monitoring across all controller variants.

Impact

This case showcases Primax’s strong capabilities in high-precision automated testing, especially in environments requiring:

• High-mix product compatibility

• Fast line changeovers

• Intelligent, algorithm-driven calibration

• Scalable modular test architectures

By transforming the testing stage into a data-driven, unmanned process, Primax helps customers uphold their brand promise—delivering reliable, high-quality products at scale.

Primax continues to enhance its automation solutions to help clients achieve the optimal balance of quality, efficiency, and long-term manufacturability.
