OBJECTIVE Covert aspects of ongoing user mental states provide key context information for user-aware human computer interactions. In this paper, we focus on the problem of estimating the vigilance of users using EEG and EOG signals. APPROACH The PERCLOS index as vigilance annotation is obtained from eye tracking glasses. To improve the feasibility and wearability of vigilance estimation devi...

BACKGROUND AND PURPOSE New-onset headache in elderly patients is generally suggestive of a high probability of secondary headache, and the subtypes of primary headache diagnoses are still unclear in the elderly. This study investigated the characteristics of headache with an older age at onset (≥65 years) and compared the characteristics between younger and older age groups. METHODS We prospe...

This paper presents a technical solution that analyses sleep signals captured by biomedical sensors to find possible disorders during rest. Specifically, the method evaluates electrooculogram (EOG) signals, skin conductance (GSR), air flow (AS), and body temperature. Next, a quantitative sleep quality analysis determines significant changes in the biological signals, and any similarities betwee...

The aim of this work was to model electro-oculogram (EOG) to find optimal electrode positions for wearable human-computer interface system. The system is a head cap developed in our institute and with it we can measure EOG and facial electromyography (fEMG) and those can be used to control the computer interface: gaze direction moves the cursor and muscle activations correspond to clicking. In ...

Electric potentials are generated across the Cornea and Retina of the eyes as a result of the movement of eyeballs within the conductive environment of the skull. This is referred to as the Cornea-Retinal Potential (CRP) and is the source of the Electrooculogram (EOG) signal. Since the occurrence of DC drifts and numerous artifacts along with power-line interference had made the EOG signal quit...

This paper proposes a new approach to real-time robot controlling by integrating an Electrooculography (EOG) measuring device within humanrobot interaction (HRI). Our study focuses on controlling robots using EOG for fulfilling elementary robot activities such as basic motor movements and environment interaction. A new EOG-based HRI paradigm has been developed on the specific defined problem of...

Routine examinations with an electroreiinogram (ERG) were performed on a large number of patients. The results are discussed in those areas where the ERG aided in diagnosis, contributed to the understanding of a disease, or assisted in following the course of a disease. The electro-oculogram (EOG) as an adjunct to the ERG is also discussed. Mention is made of the few diseases which may be detec...

Peripheral signal modulation plays an important role in sensory processing. Activity in the vertebrate olfactory epithelium may be modulated by peptides released from the terminal nerve, such as gonadotropin releasing hormone (GnRH). Here, we demonstrate that GnRH modulates odorant responses in aquatic salamanders (axolotls, Ambystoma mexicanum). We recorded electrical field potentials (electro...
