Abstract: An information processing apparatus includes a processor configured to: accept an operation performed by a user in a contactless manner for each of items displayed on a screen; and control a confirmation time for each of the items including a first item and a second item to set a confirmation time for the first item to be shorter than a confirmation time for the second item, wherein the confirmation time for each of the items is a time that is taken from when an operation performed by the user on the item is detected to when it is confirmed that the operation is selection of the item on which the operation has been detected.

Abstract: An image reading apparatus includes: a reading unit that reads an image of a document placed on a platen for placing documents; and a display unit that displays part of the image of the document read by the reading unit in a range adjacent to a range, in which the document is placed, of the platen.

Abstract: A display apparatus includes: a reading unit that reads information; and a display unit that, in response to an operation of moving a medium closer to a display surface or placing the medium on the display surface, displays on the display surface guidance information that guides a position, at which information associated with the medium is readable by the reading unit, on the display surface.

Abstract: A display apparatus includes: a display surface that displays information; and a display unit that, in response to a motion to move or place a mobile information terminal closer to or on the display surface, displays a first operation in which a first image is moved from the mobile information terminal to the display surface and displayed on the display surface, or a second operation in which a second image displayed on the display surface is moved from the display surface to the mobile information terminal.

Abstract: A display apparatus includes: a display surface that displays information; and a display unit that, in response to a motion to move or place a mobile information terminal closer to or on the display surface, displays a first operation in which a first image is moved from the mobile information terminal to the display surface and displayed on the display surface, or a second operation in which a second image displayed on the display surface is moved from the display surface to the mobile information terminal.

Abstract: A display apparatus includes: a reading unit that reads information; and a display unit that, in response to an operation of moving a medium closer to a display surface or placing the medium on the display surface, displays on the display surface guidance information that guides a position, at which information associated with the medium is readable by the reading unit, on the display surface.

Abstract: A display apparatus includes: a first display unit that displays a plurality of display elements on a first display surface, the first display surface being not touch-sensitive; and a second display unit that displays a specific display element on a second display surface, the specific display element being selected from the plurality of display elements displayed on the first display surface, by an operation performed on the second display surface.

Abstract: An icon display processor for use in a computer permits a user to intuitively recognize sub-data embedded in, or linked to, main data while a main icon symbolizing the main data is being displayed. When data B and C are embedded in document A, if a main icon is displayed, sub-icons corresponding to the embedded data are displayed behind the main icon. Thus, the user can intuitively recognize the sub-data contained in the document A. A sub-icon is displayed for each item or kind of sub-data. The user can directly process the sub-icons.
