Several drowsiness detection technologies have been developed to combat traffic accidents. Drowsiness evaluation has been attempted using the time‐series changes in nasal skin temperature. However, constructing a detection model based on this has ...

In human-machine system, human and machine need to recognize each other’s state with continuously, quantitatively and real-time property. Facial skin temperature could be measured with these properties by infrared thermography. The non-contact pro...

Previous studies have demonstrated that emotional arousal is evoked by visual feedback of a selfie. This selfie was subjectively evaluated as having a good face and a good psychological state. However, the causality between emotional arousal due t...

Hypertension is one of the leading risk factors for several diseases. Measurement and monitoring of blood pressure anytime and anywhere are important to lower blood pressure and prevent pathogenesis of diseases. Non-contact blood pressure measurem...

In automated driving at Level 3, drivers constantly need to allocate attention to the driving environment to react immediately to a take-over request. However, the amount of attention of drivers to the driving environment has not been quantified. ...

Hypertension is one of the leading risk factors for cerebrovascular, cardiovascular, and chronic kidney diseases. Regular measurement and monitoring of blood pressure is important to decrease or prevent pathogenesis of diseases. Contactless measur...

Selfies may have an effect on the psychophysiological state. The objective of the present study was to evaluate the psychophysiological state by providing feedback for selfies. The effect of the time period was also investigated. The period from t...

An imbalance of the circadian rhythm due to an irregular lifestyle leads to autonomic dystonia. The long-hour variations of the physiological indices such as core temperature and heart rate variability, associated with the autonomic nervous activi...

The amount of mental work using information equipment has been increasing because of a rapid growth of an information society. Accumulation of short-term mental work can cause various stresses and a disturbance of circadian rhythm and lead to fati...

Microelectrode array (MEA) based-drug screening with human induced pluripotent stem cell-derived cardiomyocytes (hiPSCM) is a potent pre-clinical assay for efficiently assessing proarrhythmic risks in new candidates. Furthermore, predicting sympat...

The number of patients with lifestyle‐related diseases has increased because of irregular dietary life, which is attributed in part to social issues. For maintaining a regular dietary life, managing the dietary history and information is needed. T...

Extra-high-quality audio devices, which is reproducible sound of broadband, have appeared in recent years. Such audio devices of broadband can feel like a deeper sense of realism as an air field by feeling the vibration of the air with entire body...

Broadband audio devices appear to give a deeper sense of realism as an air field by making one feel the vibration of the air through the entire body. The application of the new media of information transfer and content of sense presentation is exp...

Drowsiness is one of the leading causes of traffic accidents. A technique for fast and easy measurement of the level of drowsiness is desirable. The objective of the present paper is to evaluate the dynamics of forehead skin temperature (FHT) unde...

Human error is one of the leading causes of industrial accidents at modern manufacturing production sites. An adaptive asynchronous human–machine system (Async-HMS) was previously proposed as a new mechanism for preventing the reduction of cogniti...

It is still unclear how the activity of sympathetic and parasympathetic neurons influences the activity of cardiomyocytes in culture. We developed a device for co-culturing sympathetic neurons, parasympathetic neurons, and cardiomyocytes using mic...

The sympathetic neurons (SN) and the parasympathetic neurons (PN) have important roles in regulation of the cardiac activity. Imbalance of the SN and the PN activities results in abnormal cardiac electrophysiology and can cause several diseases su...

The magnetic stimulation is the way of stimulating the nervous and muscle tissue with the electric field induced by the stimulation coil and is widely used in the evaluation of the nervous system and the field of the exercise physiology. The focal...

The magnetic stimulation is the way of stimulating the nervous and muscle tissue with the induced eddy current induced by the stimulation coil and is widely used in the evaluation of the nervous system and the field of the exercise physiology. It ...

Vital sign monitoring in daily life is very important for the early detection of hypertension, which causes cerebrovascular and cardiovascular diseases. A non-contact vital sign sensing is essential for vital sign monitoring in daily life. Our pre...
