Provided is a display device including an input detector that detects input information input to an input surface by input devices, an input number determiner that determines, based on the input information detected by the input detector, an input number indicating the number of the input devices of which an input operation on the input surface is enabled, and a display processor that displays an attribute setting object in which an attribute of each of the input devices is settable, based on the input number determined by the input number determiner, in a specific region of the input surface.

Information processing device, information processing method, and recording medium

An image display apparatus includes a display unit displaying an image, a touch detecting unit detecting a touch operation by a touch pen, a control unit executing a process allocated to the detected touch operation, and a communication unit receiving an ID transmitted from a touch pen when the touch pen is detected to be held by a user. In response to the communication unit receiving the ID, the display unit displays a partial image indicating a state of settings related to the process allocated to the touch operation by the touch pen, and in response to a touch to the partial image, the display unit displays a menu allowing a change of settings. Thus, the user can easily confirm the state of settings related to the touch operation, and can easily change the settings.

Image display apparatus having touch detection and menu erasing

A display control device includes an identification information reception unit that receives identification information from an input device, an input unit that can receive a handwriting input through the input device, an object generation unit that generates an object from the handwriting input, and a display control unit that performs control of displaying the object on a display area, in which the object generation unit generates a tag object or a drawing object from the handwriting input based on the identification information.

Display control device and recording medium

A touch operation input device that allows input by a touch operation to a display screen, has a touch operation detector for detecting a touch operation; an operation processor for performing a process by determining operated content based on a detection result of the touch operation detector; a menu processor for performing a menu displaying process and a process of a menu item, based on a determination result of the operation processor; an image processor for performing a process of generating a drawn image on a touched portion when in a drawing mode; and a display controller for performing control of display on a display screen. When the operation processor has determined the touch operation as an operation for a menu process, the image processor performs a process of erasing the drawn image drawn by the touch operation even in the drawing mode.

Touch operation input device, touch operation input method and program

A multi-display system provided with display devices arranged to form a rectangular video display screen as a whole includes: distributors to which video signals are input; CPUs for detecting the number of input video signals; arrangement determining units for determining a display layout on the video display screen by looking-up a pre-set look-up table using the number of input video signals detected by the CPUs; and display units for displaying an input video image or images on the video display screen, in accordance with the determined display layout and the arrangement of display devices. Thus, the display layout of the multi-display system can automatically be changed in accordance with external environment.
