The comparative effects on blood ejection and perfusion between supine and elevated supine postures with upper body elevations were investigated in this study. Blood ejection and perfusion were measured by electrical bioimpedance and laser Doppler flowmetry techniques respectively in normal human subjects. Using hardware and software, electrical bioimpedance based blood ejection from heart were calculated...
Recording and processing physiological signals from real life for the purpose of affect detection presents many challenges beyond those encountered in the laboratory. Issues such as finding the proper baseline and normalization take on a time dependent meaning. Physical motion also becomes an important factor as these physiological signals often overwhelm those caused by affect. Motion also has an...
