7.0   COVVI Hand Features

The thumb has powered rotation so automatically switches between non-opposed and opposed positions. 

But it also has a novel thumb tap which is a quick, intuitive way to change grips or tables. Laterally tap the side 

of the thumb to trigger the rocker switch and activate the powered rotation without the need for a myo-input. 

The thumb will rotate between non-opposed and opposed positions depending on which grip is assigned next.
