| Key Feature | Electronic strike zone + swing analysis (dual-purpose) |
| Deployment | Taipei Dome, Taichung Intercontinental Stadium, Tianmu Stadium |
About the Exhibit
The Karma Zone (also referred to as Taiwan Hawk-Eye) represents Taiwan’s fully homegrown electronic strike zone system. While countries like the UK and US have similar systems, Taiwan developed this independently to serve the specific needs of the CPBL and national training programs .
Unlike traditional systems that only track pitch location, the Karma Zone is designed as a dual-purpose tool: it automates ball/strike calls while also providing detailed swing analysis for batters . This dual functionality makes it a unique asset in the global baseball technology landscape.
How It Works
The system uses an array of high-speed cameras strategically positioned around the stadium to triangulate the ball’s position in real-time.
| Component | Function |
|---|---|
| 6 High-Speed Cameras | Track ball trajectory and location within <1cm accuracy |
| Real-Time Processing | Displays ball speed and location within 1 second |
| Swing Analysis | Captures batter swing mechanics and bat path |
| 3D Modeling | Reconstructs pitch trajectory and batter positioning |
Unique Advantage: Beyond strike zone detection, the system provides swing analysis for batters, offering insights into bat path, contact point, and timing—making it a dual-purpose training and officiating tool .

Deployment in Taiwan
The system has been rolled out across Taiwan’s major stadiums, significantly upgrading the accuracy of officiating and training data.
| Stadium | Status |
|---|---|
| Taipei Dome | Fully operational |
| Taichung Intercontinental Baseball Stadium | Fully operational |
| Taipei Tianmu Baseball Stadium | Fully operational |
| Xinzhuang Stadium | Operational |
| Douliu Stadium | Operational |
Technical Milestones:
- Target Accuracy: Currently <1cm margin of error, with plans to reduce to 5mm
- Export Ambitions: Developers have expressed intentions to export the technology to Japan and US (minor league/grassroots levels)
- Cost Advantage: Positioned as a lower-cost alternative to Trackman/Hawk-Eye for developing baseball nations

Comparison: Karma Zone vs. Global Competitors
| Feature | Karma Zone (Taiwan) | Hawk-Eye (UK) | Trackman (US/Denmark) |
|---|---|---|---|
| Strike Zone Accuracy | <1cm (targeting 5mm) | <3.6mm | <5cm |
| Swing Analysis | Included | Separate system | Included |
| Primary Market | CPBL / Asia | MLB / Global | MLB / College |
| Cost | Lower (MIT advantage) | High | Very High |
Why This Matters
For BILA and the “Country Innovation” narrative, the Karma Zone proves that Taiwan is not just a consumer of baseball technology—it is a developer capable of producing world-class systems that compete with established Western brands . Its low-cost, high-accuracy design makes it ideal for exporting to other developing baseball nations, spreading Taiwan’s influence in global sports tech.
