Can Sleep Apnea be Detected by Heart Sounds?
Yildiz, Metin; Tabak, Zeynep; Yetkin, Sinan (2017)Objective: It has previously been shown that there are morphological changes in hearth sounds during respiration and holding breath. In this study, for the first time in the literature, it was investigated whether sleep ... -
Computer Based Eye-Writing System by Using Eog
Ulkutas, Hesna Ozbek; Yildiz, Metin (2015)The aim of this study is to suggest a faster method that would also have better accuracy rate in coding eye movements into characters compared to previously developed by EOG visual writing techniques and to develop a system ... -
Development of Computer Based Ballistocardiography System
Ozturk, Nurhan; Yildiz, Metin (2014)Ballistocardiography is a measurement method which monitors physiologic parameters such as heart rate and respiration through measuring the vibrations caused by heart beat. In this study, a computer based system which ... -
Effect of Spontaneous Saliva Swallowing on Short-Term Heart Rate Variability (HRV) and Reliability of HRV Analysis
Yildiz, Metin; Doma, Serian (2018)The effects of effortful swallowing and solid meal ingestions on heart rate variability (HRV) have been examined previously. The effects of spontaneous saliva swallowing on short-term HRV and reliability of HRV analysis ... -
Eye Gaze Location Detection Based On Iris Tracking with Web Camera
Yildiz, Metin; Yorulmaz, Muhammet (2018)In recent years, there has been an increased interest in human computer interaction systems where web cameras are used as input devices. In this study, a system developed to distinguish eye gaze locations on the screen by ... -
A Feasibility Study of Communication with Cold Stimulations
Budak, Erdem Inanc; Yildiz, Metin (2014)Some part of available sytems which requires surgery (kohlear implant) for communication of completely deaf people, other parts just heal for one side hearing impaired people (soundbite technologies). Thus, there are lot ... -
Feasıbility of Heart Rate Variability Analysis With Heart Sounds
Yildiz, Metin; Turkoglu, Zeynep (2014)Heart rate variability (HRV) analysis, which is providing information about the autonomic nervous system with non-invasive method, performed with using digitized electrocardiogram records. In this study, whether HRV analysis ... -
Gaze-Controlled Turkish Virtual Keyboard Application with Webcam
Yildiz, Metin; Yorulmaz, Muhammet (2019)In this study, an easy-to-use and inexpensive system aimed at solving the communication needs of people with disabilities such as ALS by writing with their eyes was introduced. The performance of the system are measured ... -
Issues related to reliability of HRV analysis and effect of spontaneous saliva swallowing on HRV
Yildiz, Metin; Doma, Serian (2017) -
A New PC-Based Text Entry System Based on EOG Coding
Yildiz, Metin; Ulkutas, Hesna Ozbek (2018)ome disadvantages of optical eye tracking systems have increased the interest to EOG (Electrooculography) based Human Computer Interaction (HCI). However, text entry attempts using EOG have been slower than expected because ... -
The Source of Heart Rhythm Changes Caused by Swallowing
Yildiz, Metin; Domaz, Serian (2020)Swallowing can lead to the development of syncope in people who have difficulty swallowing during food intake. It has shown that even spontaneous saliva swallowing can change heart rate variability (HRV). Recently, it has ...
