Abstract: A terminal apparatus includes a communication interface, a transparent panel configured to display an image and accept a drawing, a display superimposed on the transparent panel, an imager disposed near the display and configured to capture an image of a user, and a controller configured to communicate using the communication interface. The controller is configured to receive, from another terminal apparatus, information for displaying a model image representing another user who uses the other terminal apparatus based on a captured image of the other user, and information on a drawn image drawn by the other user using a drawing tool on a transparent panel of the other terminal apparatus, and to display the model image on the display of the terminal apparatus and a hand image of a hand of the other user holding the drawing tool and the drawn image on the transparent panel of the terminal apparatus.

Abstract: A terminal apparatus includes an input/output screen including a rectangular input/output area configured to accept touch input and display an image, a communication interface configured to communicate with another terminal apparatus including the input/output area having a different longitudinal direction, and a controller configured, upon input of an image to the input/output area of the terminal apparatus, to transmit to the another terminal apparatus an output image that contains the image and corresponds to a first square area having one short side of the input/output area as one side and to cause the another terminal apparatus to display the output image in a second square area having one short side of an input/output area of the another terminal apparatus as one side. The controller is configured to set an area other than the first square area in the input/output area of the terminal apparatus as a new input/output area.

Abstract: A transmission apparatus includes a communication interface configured to communicate with a reception apparatus, and a controller configured to acquire a depth image obtained by at least one depth camera measuring distances to a subject within a measurement range, identify, with reference to the acquired depth image, a window corresponding to a position of the subject from among a plurality of windows set within the measurement range and aligned in a depth direction, transmit a window identifier identifying the identified window to the reception apparatus via the communication interface, and for each pixel of the depth image, convert a measured distance into a relative distance within the window and transmit a resulting converted value as pixel data to the reception apparatus via the communication interface.

Abstract: An education support apparatus, which is configured to support online education conducted by connecting, via a network, respective terminal apparatuses used by an instructor and a plurality of students who are present in spaces separate from each other, includes a communication interface configured to communicate via the network, and a controller configured to receive, via the communication interface, a plurality of individual images including an image of the instructor and an image of a second student different from a first student among the plurality of students, generate, using the received plurality of individual images, a composite image representing the second student as being present in the same space as the instructor, and control a terminal apparatus used by the first student to display the generated composite image.
