EOG is a biosignal which occurs during eye activities such as eye movement and blink. EOG has a linear relationship with gaze distance. Detection object position in 3-dimensional area using gaze motion was proposed in this research. To calculate the distance of gaze motion in pixel unit, affine transform method was developed. The homogeneous matrix from five geometry processes: transformation-1...

Many odorants related to manufactured explosives have low volatilities and are barely detectable as odors. We previously reported that zinc metal nanoparticles increased rat olfactory epithelium responses, measured by electroolfactogram (EOG), to several odorants. Here, we report that nanomolar concentrations of zinc metal nanoparticles strongly enhanced olfactory responses to the explosives re...

This paper reports the results of experiments that were conducted with five subjects to determine the reliability of the use of Electro-ocular gram (EOG) for controlling computers. Experiments included vertical and horizontal eye motion. Consideration was given to identify a relationship between the angle of the gaze and signal that could be applied to cover all test subjects and generate the r...

The identification of EOG activity from the electroencephalogram (EEG) recorded from the parietal occipital region is analysed. The occurrence of ocular biosignals from scalp EEGs is mandatory for both the automated and visual analysis of underlying brainwave activity. The most prominent eye-induced artefacts are caused by the potential difference between the cornea and retina, which is quite l...

Driver sleepiness due to sleep deprivation is a causative factor of many road accidents. Reducing the extent of the sleepy driving problem by developing a countermeasure device that will monitor the sleepiness level of the driver is crucial to improve the safety of the roads. Among numerous physiological measurements, the electroencephalographic (EEG) signal seems to be the most sensitive to de...

Estimates of the cardiac field artifact were obtained for each EEG/EOG channel of all-night sleep EEG/ECG recordings by heartbeat-related averaging of the EEG. These estimates – so-called templates – can be used for minimization of the artifact, e. g. by heartbeat-synchronized subtraction of the template. The 3-dimensional nature of the cardiac field artifact is demonstrated by constructing vec...

This paper presents a low-noise inverter-based current-mode instrumentation amplifier with tunable gain and bandwidth for electromyogram (EMG) electrooculogram (EOG) biopotential signals, targeting low input noise while maintaining power consumption. The tuning method is based on pseudo-resistors, whereas the due to varactor system that controlled by same control voltage tunes gain. circuit was...
