A thumb-actuated button emergency alert communicator includes a housing having a top surface, a bottom surface, a front surface, a rear surface and first and second side surfaces. A position calculation unit is disposed within said housing. A switch is disposed on the top surface of said housing proximate to a first side surface, the switch preferably including a thumb actuated button. The thumb-actuated button is further positioned such that, when communicator is grasped in the palm of the hand, the thumb actuated button is disposed below the user's thumb and adjacent to the fingers such that the thumb actuated button may be triggered by a simple, natural downward motion of the thumb. When the thumb actuated button is triggered, the position calculation unit generates a position signal including data identifying the present position of the hand held personal emergency alert device. The communicator further establishes a communication path between itself, the application server and an emergency alert operator.
