Many vehicle accidents are caused by driver fatigue. Systems to monitor driver fatigue can contribute to a decrease in fatalities. This paper describes the development of a multi-sensor system for driver fatigue detection. The system achieves this by monitoring eye closure and wheel steering movements, and is able to alert the driver of any detected anomalies. Various techniques are suggested for...
Biometric systems are important for access control and authentication in various application scenarios. Single biometrics can be selected for authentication, but a multimodal approach is typically more reliable. In this paper, a multimodal biometric authentication system is developed. It consists of wireless sensor nodes equipped with accelerometers and infrared cameras, which enable analysis of gait...
This paper describes a monocular vision system for humanoid robots designed and built to compete in the Robo Cup Humanoid Kid Size League. The proposed vision system allows the robots to track a ball, identify goals, field lines, team mates and opponents, providing information such as distances and estimated location for the robots simultaneously, using threads. With experiments using the real robots...
Telemonitoring is a tool with proven results demonstrating clinical benefits in reducing mortality and hospi-talizations. In this context, heart rate and rhythm are vital signs of utmost importance for monitoring a patient's condition. Recent advances in mobile technologies have allowed smartphones to be of great usage in this scenario, given its processing power, connectivity capabilities, sensor...
