Abstract

In today’s world, the safety of women and children are getting worse. The crime rates against them increase at a rapid rate. The current GPS trackers or safety monitoring systems are not comprehensive enough to solve the problems. Although they can perform GPS tracking and contain other features such as pulse rate detection or SOS, however, they are unable to detect dangers and threats accurately as they are unable to differentiate exercise and Fight-or-Flight response. Besides that, as they are unable to detect threat, they will also not take any actions automatically when there is threat or danger. The method to trigger SOS, which is by using emergency button, is also not user-friendly for disabled people with hand deformity. Therefore, a women and children safety monitoring system is proposed. The research focuses on the design and development of a safety monitoring system that can monitor the safety of user, differentiate exercise and Fight-or-Flight response and send SOS message by a hand movement recognition. The safety monitoring system can monitor the safety of the user by tracking the locations of the user in real-time manner through GPS tracking. Besides that, the exercise and Fight-or-Flight response are differentiated by pulse rate sensor and gyro accelerometer sensor. Anomaly detection is applied to the system to enable the system in detecting abnormal pulse transit time (PTT) readings and hand tremor automatically when there is danger. When abnormal PTT readings and hand tremor are detected, the safety monitoring system will send SOS signals to guardians. Besides that, a hand movement recognition is also applied in the system. The wearer can send SOS message to the predefined user by performing predefined hand movement instead of pressing emergency button.
