Abstract: A mobile communication device includes at least one processor to display a user interface on a touch screen, the user interface comprising a button to receive a touch event, determine that the touch event is currently being received by the button and enter an alarm armed state, determine that the touch event ends and enter an alarm active state, and after a particular period of time in the alarm active state, trigger a communication to an emergency responder.

Abstract: A personal security system includes: a mobile electronic device including a processor and a user input mechanism, wherein the processor is adapted to provide an alarm trigger, wherein the processor is further adapted to: receive a command from a user to provide an armed alarm condition; initiate the armed alarm condition by receiving a continuous user command through the user input mechanism, wherein the continuous user command requires an active physical touch from the user; and when the user ceases to provide the active physical touch required to maintain the continuous user command, trigger an alarm condition. In some embodiments, in response to triggering the alarm condition, the processor communicates geo-location information to a remote server, wherein the geo-location information identifies the geo-location of the mobile electronic device at the time the alarm condition is triggered.
