Abstract: The flow rate of light scattering fluid is measured more easily and at a higher speed.
A flow rate measuring method according to the present disclosure includes: generating two or more speckle images by continually imaging light scattering fluid to be measured, while defining time shorter than spatial correlation disappearance time corresponding to time in which spatial correlation between speckle patterns generated by the light scattering fluid disappears as exposure time, at a time interval shorter than the spatial correlation disappearance time; and calculating direction and speed of flow of the light scattering fluid from time variation of the speckle patterns between the two or more speckle images, in which the speckle images are imaged by using an imaging device mounted with an area sensor and a pixel group of a part of the area sensor or by using an imaging device mounted with a line sensor.

Abstract: [Object] To simplify a procedure of an action between users in a virtual space. [Solution] Provided is an information processing device including: a display control unit configured to display an image of a virtual space in which a first user acts; an action information generation unit configured to generate action information indicating an action from the first user to a second user in the virtual space; and a light modulation control unit configured to control modulation of light for displaying the image of the virtual space according to the action information. There is provided an information processing device including: a captured image acquisition unit configured to acquire a captured image including a screen of a device displaying a first image; an action information extraction unit configured to extract action information from modulation of light in a part of the screen of the captured image; a response processing unit configured to perform a process in which the second user responds to the action; and a display control unit configured to display a second image of the virtual space in which the second user acts according to a result of the process.
