Abstract: An information processing apparatus includes a receiving unit that receives an operation, using a character string that is specified by multiple messages included in a predetermined topic selected by a user, from the user to register a task that involves one or more users, and a display controller that displays, as information on the task registered when the receiving unit receives the operation from the user, the information that is a combination of the specified character string and a predetermined character string that is identified based on the specified character string or the messages.

Abstract: An information processing apparatus includes a display that displays messages received from other information processing apparatuses, and transmission messages from the information processing apparatus, in a display region in a time sequence, a receiving unit that receives a transmission message responsive to a received message displayed on the display, and a transmission instruction of the transmission message, and a controller that, if a second received message different from a first received message as a message received from a link destination to which the transmission message is directed is displayed in the display region before the receiving unit receives the transmission instruction of the transmission message, controls the display such that the transmission message indicating an association with the first received message is displayed on the display region.

Abstract: An information processing apparatus includes a processor configured to, when a second message specifying a portion of an original image included in a first message and having a link information associating the second message to the first message is received, display the portion of the original image specified in the second message with the original image based on the link information that identifies the first image being associated with the second message.

Abstract: An information processing apparatus includes a conversation presentation unit that present conversation contents in a conversation, which is performed by plural persons, in time series, a reception unit that receives a request, an urging presentation unit that presents urging of a response to the request, and a shifting unit that shifts a screen so as to be capable of presenting a conversation content before or after the request is made, in a case where the response is made.

Abstract: An information processing apparatus includes a feature extraction unit that analyzes a video to extract a feature element, a discriminating unit that, based on a difference in the feature element for each of multiple portions of the video, performs discrimination that discriminates between an explaining scene and an explained scene, the explaining scene being a scene providing explanation, the explained scene being a captured scene of what is explained in the explaining scene, and a categorizing unit that categorizes each portion of the video based on a result of the discrimination.

Abstract: A notification apparatus includes a registration unit that registers plural participants for each work, a positional information acquisition unit that acquires pieces of positional information of the participants, and a notification unit that notifies at least one participant out of the participants when a positional relationship between the participants is a predetermined positional relationship based on the pieces of positional information of the participants.

Abstract: An information processing apparatus includes a display that displays a message, and an association unit that associates a first message including an image with a second message that includes a character string that is entered in a state that an original image of the image is displayed via the image on the display.

Abstract: An information processing apparatus includes a receiving unit that receives an operation, using a character string that is specified by multiple messages included in a predetermined topic selected by a user, from the user to register a task that involves one or more users, and a display controller that displays, as information on the task registered when the receiving unit receives the operation from the user, the information that is a combination of the specified character string and a predetermined character string that is identified based on the specified character string or the messages.

Abstract: An information processing apparatus includes a receiving unit that receives an operation that, using a character string that is specified by multiple messages about a predetermined topic, registers a task that involves one or more users, and a display controller that displays, as information on the task registered when the receiving unit receives the operation, information that is a combination of the specified character string and a predetermined character string that is identified based on the specified character string or the messages.

Abstract: An information processing apparatus includes a processor. The processor is configured to associate plural terminals with a service, the plural terminals being registered for the service and located within a predetermined range, set, based on use statuses of the plural terminals located within the predetermined range, priority levels for the plural terminals, and transmit a notification regarding the service to a terminal with the highest priority level.

Abstract: In a telepresence scenario with remote users discussing a document or a slide, it can be difficult to follow which parts of the document are being discussed. One way to address this problem is to provide feedback by showing where the user's hand is pointing at on the document, which also enables more expressive gestural communication than a simple remote cursor. An important practical problem is how to transmit this remote feedback efficiently with high resolution document images. This is not possible with standard videoconferencing systems which have insufficient resolution. We propose a method based on using hand skeletons to provide the feedback. The skeleton can be captured using a depth camera or a webcam (with a deep network algorithm), and the small data can be transmitted at a high frame rate (without a video codec).

Abstract: An information processing apparatus includes a storage section that stores artwork information related to each of plural artworks and a connection relationship among the plural artworks, a specifying section that specifies an artwork in the connection relationship with an artwork selected by a user among the plural artworks from the relationship stored in the storage section, and a presentation section that ranks an artist of the artwork specified by the specifying section and presents a result of ranking.

Abstract: A height calculation system includes a capturing section that captures an image, a detection section that detects a specific body part of a human in the image captured by the capturing section, and a calculation section that calculates the height of the human based on the size of the part when the one part detected by the detection section overlaps with a specific area present in the image.

Abstract: A hand-raising detection device includes a converter and a detection unit. The converter performs conversion of a predetermined space including a person into an overhead view image by using a result of three dimensional measurement performed on the predetermined space. The detection unit performs detection of a hand-raising action by using a silhouette image of the person in the overhead view image resulting from the conversion performed by the converter.
