The iKey KYB-170-OEM wrist keypad is an updated version of the iKey AK-39 keypad. Both meet military specifications and can be integrated to control computers worn on your wrist. The KYB-170-OEM features a 17 button keypad, an integrated micro Force Sensing Resistor (FSR) pointing device and can be manufactured with any available color of LED lighting for use in dark environments.
The only problem is that you can’t unleash your secretary-grade typing speed on it because this updated version operates like a cellphone, meaning you’ll have to press “7” four times to get the letter “S”. If you’re using this for military applications, that’s probably not what you want to be focused on in the heat of battle.
