Microsoft Create Magic Multi-Touch Wall

After Microsoft Surface and its use for a BMW, then Microsoft will be demonstrating its multi-touch computer and interface is the new magic, called TouchWall at the Microsoft CEO Summit in Redmond.
TouchWall more referring to the ability of touchscreen hardware setup itself, plus software that will run TouchWall, which was built in the standard version of Vista, called Plex.
TouchWall and Plex almost the same as those used in Microsoft Surface, a multi-touch table computer that was introduced in 2007 and became a commercial item in the store AT & T.

In his demo, Microsoft Office Labs GM Chris Pratley, and Director of Envisioning Ian Sands said that the two products, Microsoft Surface and TouchWall are different things.
Surface is a multi-touch and vision system that uses cameras to sense what is on the table, where, and what can be done at the table.
For example, when the phone is placed on the table, and then interact with what's on the table in various ways, such as pulling photos into the phone.

However, TouchWall is a simple mechanical system, and cheap to produce.
Surface required for the production costs of $ 10,000, because the hardware must be transformed into a multi-touch interface.
While for TouchWall, according to Sands, only a few hundred dollars needed for its production.
TouchWall has three infrared lasers that can scan the surface.
A camera will record when something broke the line of laser and provide information back to the Plex software.
According to Pratley and Sands, a prototype is made very simple.
A projector used to show the Plex interface on the cardboard screen prototype.

Sands also explained the activities that can be done with TouchWall, such as zooming in and out, play the media, even using a drawing tool for drawing the entire screen like a whiteboard.
The only limitation is the projector is used, which means that actually the whole wall can be a multi-touch interface.
Microsoft was too early to say it will not sell TouchWall.
This is caused by Pratley, computer experience in the future is the absence of a monitor, keyboard, mouse and more to a table architecture,
with user input directly on the screen and via voice commands, with keyboard and mouse input only for entering data or typing editing.
