iKey's rugged AK-39 keyboard is designed to be worn on the arm, providing a simple, compact data-input solution that does not restrict the user's arm movements.

The AK-39's small-footprint design features essential components for military and public safety applications, including an integrated Force Sensing Resistor^TM (FSR) pointing device with left- and right-click functionality, and adjustable green LED backlighting that is also available in a night vision (NVIS) compatible configuration. Designed with gloved users in mind, the AK-39's snap-on faceplate eliminates accidental key strokes and can be easily removed to clean the pad
