What is the digital signage?

The digital signage is the electronic advertisement medium which uses the computer for display and communication. With its communication function, it can obtain and display the new information all the time as well as control from the distance. The advertisement movie can be freely changed and you do not need to go to the place where the poster is posted and change it any more. Moreover, as this system is controlled by computer, the information such as the contents and layout can be automatically changed based on the situation.

Available for various mediums

The digital signage system is available for various mediums such as the information terminal and wall display including normal display, multi-display system, multi-media station. The multi-display system provides the special effect by displaying a movie on multiple screens and displaying different movies on each screen. The digital signage systems in different places can be controlled and managed together, and it is easy to display the same advertisement in many different places and integrate the contents of each display. It enables the advertisement medium to move autonomously by the combination with the robot such as ALSOK An9-PR. It is expected the effective display of advertisement due to the free control function which allows the switching of advertisement contents based on the place and time, and the special news flash services in an emergency situation. Currently, this system has been used for not only for advertising but other purposes such as the navigation board and news flash.

Interactive digital signage

The interactive digital signage is the digital signage system which enables to change the displayed movies and contents based on the human behavior by the interactive operation. The human behavior is detected by the touch panel and RGB camera sensor, and the displayed contents are changed based on its movement. In the case of advertisement, the detailed information is displayed, and the special effects such as wind and vibration are added to the movie. One of the actual examples is REACT by ITTOCAN (Figure1). The REACT is the drawing engine of the video installation for the space creation using RGB camera sensor. The special effect is added based on the human behavior such as waving the hands and walking in front of the camera. The cluster system is structured by PC built-in display, and it can be displayed on multiple screens. The Intel digital signage end cap is one of the interactive digital signage (Figure2). It is the shopping terminal using RGB camera and infrared depth sensor. With the facial recognition technology, the product appropriate for the person is displayed by the assumption of the gender and age from the face. In addition, it is possible to select and purchase the products without touching the screen by detecting the human movement with infrared depth sensor.   Figure1(Above) REACT by ITTOCAN (Exhibition booth of Digital Signage Japan 2011) Figure2(Right) Digital signage end cap by Intel (Exhibition booth of Digital Signage Japan 2011) *Digital Signage Japan 2011 URL:http://www.f2ff.jp/dsj/

Intuitive operation and multi-screen synchronism display using infrared depth sensor

FORUM8 has developed the Multi-Cluster digital signage system using the infrared depth sensor. Currently, the 6 screens of cluster signage is settled in the showroom in the Tokyo head office (Figure3, 4 5). Figure4 Overview of Multi-Cluster digital signage system with infrared depth sensor Figure3 6 screens of cluster signage Figure5 Display image The infrared depth sensor allows the intuitive operation. In addition, the Multi-Cluster system enables the synchronism display on 6 screens. The infrared depth sensor is setup at the bottom of display. The intuitive operation is available by using it, without touching the display and computer. This infrared depth sensor is scheduled to use Kinect(TM) sensor or XtionPRO (Figure6). The effective range of both sensors is about 3.5m, and the digital signage system can be freely controlled within that range (Figure7). Kinect(TM) sensor XtionPRO Figure6 Infrared depth sensor (Kinect(TM)､XtionPRO)  Figure7 Kinect(TM) infrared depth sensor Only the infrared depth sensor is mounted on XtionPRO, and the system can be downsized. Kinect(TM) sensor has the camera and microphone additionally so that you can operate with the voice.

Multi-Cluster system similar to 8DOF DS

The Multi-Cluster system uses the system similar to the very large type of DS system, 8 DOF (8 Cluster Driving Simulator) (Figure8). The Multi-Cluster system uses multiple machines to generate the movie, therefore, it can keep the high frame rate while the highly-loaded image process. In addition, the display property can be set by the machine on control side, and you don't need to touch individual machine separately.   Figure8 8DOF Multi-Display system In 6 screens of cluster signage system, RGN camera will be settled at the upper side of display to register the the operational movement. The acquired information from RGB camera is transferred to the development team as feedback so that it is expected to be used for the improvement of the operability (*1). *1)Acquisition and use of data is performed only after getting the permission.
