A predetermined process is executed in accordance with a state of a detection target which has been detected through short range communication with the detection target. In a case where a control device (100) has determined that a location of an NFC tag (30) detected by a display device (10) had changed, the control device (100) causes the display device (10) to transmit predetermined information to the communication terminal (20) via an NFC antenna (11).

A transaction medium comprises a non-e-paper portion and a passive e-paper display portion to display a first expression of an authentication element in a secure representation. The first expression is related to a second expression of the authentication element, wherein a comparison of the first expression and the second expression determines authentication.

Briefly, a method for verifying the visual perceptibility of a display is provided. An intended message is written to a bistable display. Pixels that comprise portions of the message are measured and evaluated to determine if the message actually displayed on the bistable display was perceptible by a human or a machine. In some cases, information regarding the message actually perceivable from the display may be stored for later use. Responsive to determining that a message is perceivable or not perceivable, alarms may be set, one or more third parties notified, or additional display features may be set.

Systems, apparatus, methods and computer program products are described below for rendering a graphical user interface by selectively compositing display contents. In general for each of one or more content producers, where each content producer is associated with content storage containing display content, display content for output is identified depending on the content consumer to which the graphical user interface is being rendered.

A method for determining the color depths of the video data for a selected frame in High-bandwidth Digital Content Protection (HDCP) video data transmitted over a High Definition Multimedia Interface (HDMI), in which (a) the beginning of the selected frame is marked with a vertical synchronization (VSYNC) signal and (b) a mark in a window of opportunity (WOO) for the selected frame indicates whether or not that frame is encrypted. The method detects, for the selected frame, the length of the interval between a VSYNC signal and the location of at least one of (i) the start of the corresponding WOO and (ii) the mark indicating whether or not the selected frame is encrypted, and then determines the color depth of the video data for the selected frame based on the detected length.

A system and method of adaptively sharing at least one portion of a web page between computing devices by a processor may include: associating an identification of at least one first client computing device with an identification of one or more second client computing devices; receiving at least one client property of the one or more second client computing devices; receiving an indication of an event relating to presentation of the at least one web page portion on a screen of the first client computing device; adapting, in real time, at least one presentation property of the at least one web page portion, based on the event indication and on the at least one client property; and presenting the at least one web page portion on a screen of the one or more second client computing devices, based on the association of identification, and according to the adapted presentation property.

A head mounted display which enables a user to visually recognize a virtual image includes: an image display unit that causes the user to visually recognize the virtual image; a processing unit that processes display information, which is information displayed to the user as the virtual image, in the image display unit; and a transmission unit that transmits the processed display information to an image display apparatus which is connected to the head mounted display.

An electronic certificate and a display method therefor are disclosed. The electronic certificate includes an electronic certificate body, a display screen and an IC. The display screen is disposed on the front side of the electronic certificate body and is used for displaying project information of the electronic certificate. When the display screen is in a locked state, the display screen does not display any project information. The IC is connected to the display screen and is used for controlling a display function of the display screen.

A method of managing a control authority over a digital signage includes, if a search request for a digital signage is received from a first user device, providing, to the first user device, information upon at least one digital signage over which the first user device is capable of making a request to have a control authority; and if a request for a control authority over a first digital signage is received from the first user device, determining the control authority over the first digital signage to be assigned to the first user device with reference to context information regarding at least one of the first user device, a user account related to the first user device and the first digital signage.

According to embodiments of the invention, apparatuses and devices are directed towards a modular electrofluidic display. The electrofluidic display may be capable of displaying imagery both on a front side and a rear side of a display. This is carried out by adding a fourth oil layer to a display panel which traditionally may have employed two or three oil layers. In a traditional display mode, the color of the oil on the fourth layer may serve as the background color of the pixel. Light from the rear is blocked by the fourth oil layer. In a mode where both sides of the display are required to display images, the oil in the background layer may be displaced with a voltage applied so that light can traverse to all the colored oils from both front end as well as the back end of the display.
