An electronic apparatus and a method of controlling the same, the electronic apparatus including: a display; and a processor configured to: receive a writing input for user authentication, identify writing content of the writing input and pen attribute of the writing input, perform the user authentication based on whether the identified writing content of the writing input and pen attribute of the writing input match writing content and pen attribute obtained in association with authentication data of a user registered prior to the writing input being received, and control the display to display an image based on the writing input according to which the user authentication has been performed.

A method may include presenting an image capture user interface on a display device of a multipurpose device including a live view portion configured to display a live view of image data currently sensed by an image capture device of the multipurpose device and a recall portion configured to display a thumbnail preview of stored image data most recently captured by the image capture device; receiving an indication of a first touch input on the display device, the first touch input starting at a first position on or near the recall portion of the user interface; receiving an indication of a swiping gesture from the recall portion to a second position with contact being maintained of the first touch input; and in response to the first touch input, displaying an enlarged preview of the stored image data, the enlarged preview being larger in size than the thumbnail preview.

An electronic device and a method are adapted to identify window control commands in a multi-window system. The electronic device displays multiple windows each respectively having a title bar on a touch interface. The electronic device executes the method to identify a window control command according to a touch gesture from a movement of a touch point detected on the title bar of one of the windows. The user can easily touch the title bar to operate a certain window.

A production plan display system for a shaped article includes a display unit configured to display a screen showing production plans for shaped articles of a plurality of types. On the screen, information on the shaped articles of each type is displayed in accordance with priority rankings for changing the production plans. The priority rankings are determined in accordance with information on a production deadline of the shaped articles of each type, information on a stock of the shaped articles of each type, and information on a production status of the shaped articles of each type.

A method includes receiving, a request to display a set of application views. In response to receiving the request to display a set of application views, a set of application views is displayed. The set of application views includes a first application view that corresponds to a first application that is not in an active session, and the set of application views are arranged in an order of application views. Displaying the set of application views includes: displaying a second application view that corresponds to the second application before the first application view in the order of application views in accordance with a determination that a second application is in an active session; and displaying the first application view in a first position in the order of application views in accordance with a determination that there are no applications in an active session.

A system and method for aligning a screen protector to a cell phone comprises a screen protector with an alignment liner disposed over the screen protector; alignment indicia disposed on the alignment liner; and a display source configured to enable display of alignment indicia on the display screen of the cell phone. The alignment indicia of the display screen correspond to the alignment indicia of the alignment liner so that the alignment indicia of the alignment liner is capable of being aligned over the alignment indicia on the display screen to properly align the screen protector with the display screen when the screen protector is positioned above the display screen.

A projector includes a first acquisition unit, a detection unit, a second acquisition unit, and a display control unit. The first acquisition unit acquires a captured image of a range containing a display surface by a camera. The detection unit detects a first bright point and a second bright point corresponding to reflected lights of a first light and a second light radiated substantially parallel to the display surface by a pointer from the captured image. When a distance between a position of the first bright point and a position of the second bright point is less than a first threshold, the second acquisition unit acquires a third position determined based on the first bright point and the second bright point. The display control unit displays a display image containing a drawn image by the pointer in the third position.

A projector includes a first acquisition unit, a second acquisition unit, a first determination unit, and a display control unit. The first acquisition unit sequentially acquires a first captured image and a second captured image on a display surface. The second acquisition unit acquires a first brightness value and a first position of a bright point contained in the first captured image and a second brightness value and a second position of a bright point contained in the second captured image. The first determination unit determines whether the second brightness value is larger than the first brightness value by a first threshold or more and the second position is closer to a camera than the first position. The display control unit displays a display image containing a drawn image showing a drawn line by a pointer when a determination result is negative, and displays a display image not containing the drawn image when the determination result is positive.

A method may include presenting an image capture user interface on a display device of a multipurpose device including a live view portion configured to display a live view of image data currently sensed by an image capture device of the multipurpose device and a recall portion configured to display a thumbnail preview of stored image data most recently captured by the image capture device; receiving an indication of a first touch input on the display device, the first touch input starting at a first position on or near the recall portion of the user interface; receiving an indication of a swiping gesture from the recall portion to a second position with contact being maintained of the first touch input; and in response to the first touch input, displaying an enlarged preview of the stored image data, the enlarged preview being larger in size than the thumbnail preview.
