Abstract: [Object] To provide an information processing device, an information processing method, and a program, which are capable of causing a device which is desirable to the user among a plurality of devices to give a response. [Solution] An information processing device including: an input unit configured to obtain information related to a voice of a user and device information of each of a plurality of devices; and a selecting unit configured to select a device from the plurality of devices on the basis of an aspect specified by at least one of the information related to the voice and the device information obtained by the input unit and the device information.

Abstract: [Object] To process an image captured by a camera mounted on a moving object device or a user to be suitable for display on an image display device fixed to the head or face of the user. [Solution] The image rendering processor 1042, in the beginning, corrects the user's head posture angle qh using the camera posture angle qc (F1421), and clips a display angle of view depending on the corrected user's head posture angle qh* from the captured image to render a free viewpoint image (F1422). Then, the image processing device 1040 transmits the free viewpoint image rendered by the image rendering processor 1042 to the display device 1020 via the communication unit 1041, and the image is displayed on the display device 1020 (F1430).

Abstract: There is provided an information processing apparatus, including a first information acquisition section which acquires priority action information, a second information acquisition section which acquires biological information related to a body clock of the user at a present time, a state setting section which sets an ideal state of the body clock corresponding to the priority action, a state estimation section which estimates a present state of the body clock at the present time, a third information acquisition section which acquires set action information related to a set action, and a display control section which displays a state of the body clock in the schedule on a display section.

Abstract: A wide angle image to be displayed on a screen fixed on the head or the face of a user is processed. When a display view angle reaches a boundary of an original wide angle image 701, an indicator 703 indicating reaching the boundary is added to a free viewpoint image 702. The indicator 703 is apart of the free viewpoint image 702 which is in contact with a boundary 704 of the wide angle image 701 or protrudes from the boundary 704 and is displayed as a black-painted frame. By observing such the indicator 703, the user can intuitively understand that the display area reaches the limit of the wide angle image.

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.

Abstract: There is provided an information processing apparatus, including a first information acquisition section which acquires position information related to a present position of a user and time information which shows a present time at the present position, a second information acquisition section which acquires body clock information related to a body clock based on biological information of the user, and a display control section which displays a map image on a display section. The display control section identifies and displays a location corresponding to a time difference between the present time and a time of the body clock, with respect to the present position, on the map image.

Abstract: Dialkyl-trisulfides having a minimum grade of copper-strip corrosivity which are suitable as extreme-pressure additives, are produced at high selectivity by reacting alkyl-mercaptans and sulfur at a quantitative ratio in a range of 0.5 to 1.0 gram atom of sulfur to 1 mol of alkyl-mercaptan in the presence of magnesium oxide as catalyst.
