Abstract:
Provided is an image display device configured to display a free viewpoint image that tracks a movement of observer's head and trunk. The line-of-sight direction and trunk orientation of the user are individually oriented in a free viewpoint space displayed on a display device 500 based on posture information of the user's head and trunk, which are respectively obtained from a head motion tracking device 200 and a trunk motion tracking device 300. A behavior that is natural in real space can be represented by moving a line of sight to a front direction of the trunk on a space in a state where the line of sight does not match the front direction of the trunk. An unnatural UI that goes straight to the line-of-sight direction is prevented regardless of orientation of the trunk.

PROBLEM TO BE SOLVED: To provide a new device and a method for evaluating blood quality.SOLUTION: As a result of obtaining and analyzing ultraviolet-visible light absorbing spectra of erythrocytes, it has been found that multiple spectrum patterns are detected corresponding respectively to spectra of heme and its decomposable organisms biliverdin and bilirubin for different erythrocytes or the same erythrocyte at different time points. Consequently, a blood analyzer is provided including an analysis unit which compares a measured spectrum obtained for an erythrocyte with a standard spectrum of the heme, the biliverdin, and the bilirubin, to attribute the measured spectrum to one of them. By using the blood analyzer, and depending on whether the measured spectrum obtained for the erythrocyte matches any one of the standard spectra, a decomposition degree of the heme in the erythrocyte is evaluated to be used as an indicator of time degradation of the erythrocyte.

PROBLEM TO BE SOLVED: To provide a new device and a method for detecting echinocytes contained in blood.SOLUTION: As a result of obtaining and analyzing visible absorption spectra of erythrocytes, it has been found that echinocytes exhibit a characteristic spectrum pattern accompanying an absorption peak in a wavelength region of 450-490nm between a Sorbet band and a Q band. Consequently, a blood analyzer is provided including an analysis unit for detecting the absorption peak of the visible absorption spectrum obtained for blood. By using the blood analyzer, the echinocytes contained in the blood can be detected based on the absorption peak.
