The sensor that detects the movement of the trackball is equipped with a gaming-grade high-performance optical sensor, and the optimization of the new high-performance lens and surrounding optical design has achieved outstanding pointer tracking. The use of a large artificial ruby with a diameter of 2.5 mm for the support ball improves the feel of the ball. In addition, the larger diameter of the support ball makes it less likely to become buried in dirt such as hand grime, reducing the frequency of maintenance. The design focuses on the six bones and muscles of the hand that come into contact with the device during operation, and takes into account the depressions and bulges, achieving a new "feel" that is easy to operate, as if the shape of the palm of the hand is reflected as it is.
