Coolso

Coolso develops wearable gesture-recognition technology. Using patented sensing that detects muscle-vibration signals processed through its own AI model, Coolso recognizes individual finger movements and strength levels with low-latency response, from a wrist-worn device or an ordinary smartwatch's accelerometer and gyroscope without dedicated hardware. Founded by Sheng-Kuei Hsu, Wei-Lin Lee, and Jack Wu and based in Cambridge, Massachusetts, the seed-stage company is backed by 500 Global and Alchemist Accelerator and targets AR/VR interaction, with potential expansion into medical rehabilitation and sports equipment. Coolso publishes no public API, SDK, or developer portal at this time.

Coolso is profiled on the APIs.io network. Tagged areas include Company, Wearables, Gesture Recognition, Artificial Intelligence, and Sensors.

Coolso’s developer surface includes engineering blog, support, and 2 more developer resources.
