The disclosure generally relates to systems and methods for allowing a person to activate a distress signal via a portable device, such as a mobile phone, without having to physically look at the portable device. For example, if a victim is being held hostage, and cannot use their mobile phone in plain sight of the hostage-takers, the present invention allows the victim to silently activate a distress signal that can be sent to various third-party response providers, such as a 911 dispatch center, a private security/monitoring service and a friends and family network. The distress signal is activated through various software and/or hardware based tactile mechanisms and buttons provided on the portable device. |
