About U-BRAIN Ring TOP ↑
  Revolution of wearable devices  
We require a complex system equipment in order to visualize the position and posture of the three-dimensional space. In a compact housing, and Because it is equipped with a battery and a wireless unit and the CPU and sensors, "U-BRAIN Ring" does not require any equipment other than (or smartphone or tablet) PC.
  Output format that is easy-to-use application  
  This ring-type motion sensor, so we signal processing in advance internally, it can be used without application to post-process the data terminal receives. It is a sensor for the application.  
  Data easy to handle  
  The combination of a 15 axis sensor (gyroscope, acceleration, geomagnetism, light, sound, temperature, etc.) and a radio unit realizes integrative package control and measurement.
Moreover, since firmware mounting of the patent acquisition technology is carried out into CPU, high-speed and easy signal processing is possible.

     Development Kit

The ring type motion sensor "U-BRAIN Ring" can control various applications carried in PC, a tablet, etc. through API by using middleware "U-BRAIN DSM."

You can develop applications by using a development kit that set of ring-type motion sensor as "U-BRAIN Ring" middleware "U-BRAIN DSM".We offer to the target (wearable developers, mobile device developers, video producers, CG creators, such as VR / AR system producers, for example) towards state-of-the-art ITC many areas, this development kit.
