Photoplethysmography (PPG) is one of the simple and non-invasive heart rate (HR) sensing methods, but when applying it to a person during exercise, the output is contaminated with motion artifact (MA). Furthermore, when the pressure to stabilize the sensor on the skin surface is lower, extremely large values referred to as "outliers" are often observed in the sensed heart rate. To cancel...
Real-time vital sensing for persons during exercises is important for effective physical training, healthcare and injury/disease prevention. We have developed a vital sensor node which can sense heart rate (HR), energy expenditure (EE) and body temperature (BT), and furthermore can transmit the sensed data by wireless in real-time, just by hanging itself with the clip at the rim of undershorts. The...
Cameras are embedded in many mobile/wearable devices and can be used for gesture recognition or even sign language recognition to help the deaf people communicate with others. In this paper, we proposed a vision-based gesture recognition system which can be used in environments with complex background. We design a method to adaptively update the skin color model for different users and various lighting...
Artificial skin systems support human-robot interactions through touch. The interpretation of touch modalities indeed represents a crucial component for the future development of robots that can properly interact with humans. Independently of the specific employed transducer, one of the key issues is how to process the massively complex and high-dimensional tactile data. In this paper, machine learning...
The research on human-robot interaction (HRI) has been an emerging topic of interest for both basic research and customer application. The studies specially focus on behavioral and cognitive aspects of the interaction and the social contexts surrounding it. HRI issues have long been a part of robotics research because the goal of fully autonomous capability has not been met yet. One of the most challenging...
The emerging field of medical robotics is aiming in introducing intelligent tools to perform medical procedures. In particular, robotic researchers have been proposed advanced medical training systems to enhance motor dexterities of trainees. An efficient medical training system should be designed to simulate real-world conditions and to assure their effectiveness as the representation of the motor...
It is believed in oriental Chinese medicine that some special points called acu-points, and meridians connecting such acu-points, are existing in the human body. The acupuncture is accordingly such a medical treatment to cure the illness or to keep the human body healthy by stimulating related acu-points particularly those on a meridian. Acupuncture was originated from ancient China with the typical...
