The UC3M4Safety team is composed of five research groups in the Carlos III University of Madrid (UC3M) and one group in the Polytechnic University of Madrid (UPM). The UC3M provides a high degree of interdisciplinary research for international research projects where Social and Human Sciences must connect and collaborate with Information and Communications Technologies, for improving the quality of life of people. Four departments in the Polytechnic School face the problem of preventing and combating the violence from a technological point of view. Signal Theory and Communications Department, Telematics Engineering Department, Mechanical Engineering Department and Electronic Technology Department apply their knowledge to use the most recent smart sensors, recognition algorithms and security in wireless networks in a proposal that protect victims. On-line detection of human moods, dangerous objects or aggressors, with a "transparent" wearable system, would allow victims to prevent and combat new episodes of violence. Of course, this system is assessed by the Gender Studies Institute (Social Sciences Faculty) thanks to its large knowledge in violence against women and protecting victims. Additionally, researchers from Center of Industrial Electronics, (UPM-CEI), experts in Wireless Sensor Networks will provide their expertise in machine learning algorithms for multi-sensor data treatment.
