At the Digital Signage Japan 2011 exhibition, NEC showed a trial digital signage solution called Multi-Touch Wall, which can smoothly display high-volume content on a large multi-display.
This system is controlled by a single computer using Windows
Embedded Standard 7, NEC Display Solutions’ MultiSync displays, and Intel processors.
“We set up eight extremely thin-bezel 46-inch LCD displays, and used an infrared sensor to make the front surface into a touch panel. The special feature is the ability to simply operate so many screens interactively.”
The resolution of a single display is 1,366 by 768 pixels in WXGA mode, so the eight displays have a resolution of 5,464 by 1,536 pixels. Ordinary glass is used for the surface, and currently multi-touch can be detected at two points using infrared.
“We want to promote this to corporate showrooms and product promotion booths, as well as in situations where people want to show content much more realistically by being able to enlarge and shrink images. The system can also be used as an interactive education tool, allowing students to write on the right half of the screen and images and text to be shown on the left side.”“Actually this product is being installed in Microsoft’s new showroom. Right now, it is in exhibit form for display, but we are already finishing custom products. We will offer it to particular customers as a solution to match their needs in the future.”
