A wearable computing system can comprise a device attachment mechanism and a push to talk actuator. The device attachment mechanism can include a device coupler and a body affixer. The device coupler can detachably couple a portable computing device to the device attachment mechanism. The body affixer can detachably affix the device attachment mechanism to a forearm of a user positioned between a wrist of the user and an elbow of the user. The push to talk actuator can be activated by the user utilizing at least one of an arm, a hand, a wrist, and a finger movement. The push to talk actuator can be coupled to an actuator attachment mechanism that is wearably attached to the user in a hands-free fashion.
