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.

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 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.

Methods and systems are provided for presenting a plurality of shared calendars in a single electronic display frame or window where each of the plurality of shared calendars is displayed in a common view mode relative to other displayed shared calendars. Users may select one or more shared calendars to be displayed in the same display frame or window as their own calendar. Upon selection of a shared calendar to be displayed alongside a first calendar, an aggregate view object is called to control and coordinate all shared calendars selected for display in the common window or frame. The aggregate view object determines the view data object, including view mode (hourly, daily, weekly, monthly) and other calendar display settings of the first or active calendar displayed in the common view of shared calendars.

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.
