Every 98 seconds, a person in the United States is sexually abused. Every 16 hours, a woman in the United States is murdered by her romantic partner or ex-partner. Sexual abuse, assault, and harassment are regarded as some of the most common human rights violations in the world by the United Nations. Our work examines methods to prevent sexual assault, from pre-historic times to latest technologies, to inform contemporary designs. In this thesis, we investigate multiple methods to detect initial signs of assault and develop methods for communication and prevention of assault. We also explore olfactory stimuli as a potential means to prevent sexual assault in real-time.
