Abstract: A wearable security system integrates sensors, such as optical and acoustic sensors, a decision engine processor, a communications device, such as a cellular telephone, a location determination device, such as a GPS system, a device controller, and user feedback. A method of wearable security operates the wearable security system so that a user is aware of and able to control and interact with his or her environment, such as providing notice of potential threats or taking protective actions.
