The spectral analysis of Heart Rate Variability (HRV) can be used for assessing the autonomic nervous activities and further the physiological conditions of subjects. This study intended to explore whether or not people would have fatigue, faintness and other kinds of uncomfortable conditions after watching a 3D film by using HRV measures as the objective physiological indices, in addition to other...
In this research, the diffractive blazed grating was proposed to produce the stereoscopic effects that were traditionally generated by barrier grating through parallax barrier method. Three wavelengths, 596nm, 554nm and 450nm, were chosen as the main light waves for three sub-pixels, RGB. Because the diffractive optical element was directly attached to the color filter of a MPEG-4 player (Motion Picture...
This research is to design a microprism array optical film which can be attached on 2.2-in. liquid crystal displays. The sizes of the base width of the microprism and the sub-pixel of the panel were corresponding. After the selection of the appropriate vertex angles, two images could be delivered to left and right viewing zones of the panel. This research also used flexible material polydimethylsiloxane...
