Transcribed Image Text: The Boeing Company (www.boeing.com) is a U.S.-based multinational corporation that designs,
manufactures, and sells airplanes, rotorcraft, rockets, and satellites globally. The company is the
second-largest defence contractor in the world, behind Lockheed-Martin
(www.lockheedmartin.com).
Boeing designed its Collaboration Center in its Arlington, Virginia, regional headquarters
to provide new ways of engaging with the company's global customers. The Center enables
Boeing to present its capabilities in an immersive, visual environment that encourages close
collaboration with its customers. Boeing's intent is to deliver a customer engagement experience
unlike any that its customers have previously seen. In addition, the Center wants each customer
to have a customized experience.
The Center consists of 7,500 square feet of multi-use spaces. Customers first see a 27-by-
8 foot Entrance Feature. This large screen offers an audiovisual presentation of Boeing's diverse
capabilities. The screen is composed of Christie MicroTiles. The tiles are modular, rear-
projection cubes that can be placed to form a large vidco wall-stylc display. Customers are then
greeted at the Welcome Wall. This 3-by-3 array of Samsung 55-inch multitouch displays
communicates customized messaging and includes the objectives for the meeting, agenda details,
and concierge features, which can include real-time flight arrival and departure information as
well as a 100-year history of Boeing.
A pair of Collaboration Rooms feature Cisco videoconferencing systems and 90-inch
Sharp displays that include touch interfaces that create comfortable, flexible spaces that are ideal
for effective collaboration. These rooms can be configured in different ways. Alternatively, they
can be combined into one large working environment.
Next to the Collaboration Rooms is the Launch Window, which offers sofa seating in
front of a 90-inch interactive Sharp display screen. This screen can present three-dimensional
content to showcase Boeing products and touch-enable simulations.
The Global Presence Wall features a 3-by-3 array of Samsung 55-inch multitouch
Transcribed Image Text: displays with custom content about Boeing's global presence, featuring supplier information,
economic impact, and corporate citizenship initiatives. Customers can drill down and see details
by country and by global location.
The highlight of the Collaboration Center is the One Boeing Wall, a display consisting of
18 Samsung 55-inch monitors. The Wall has audio and video conferencing capabilities as well as
a multitouch capability that enables multiple customers to explore and cross-reference Boeing
products and services at the same time. After a collaboration, documentation annotated on the
Wall can be saved and sent to customers for follow-up.
The same application supporting the One Boeing Wall also supports two multitouch
interactive table displays that are located at opposite ends of the Collaboration Center. Each table
contains two embedded 42-inch multitouch computers that feature object recognition. Boeing
staffers and customers can place an object, such as carbon fibre or a product model, on these
tables to obtain a deeper understanding of the object's capabilities.
In the Centers' Horizon Theater, customers experience presentations, webcasts, and flight
simulations. Customers can also engage in two-way video and audio conferences with remote
participants such as Boeing executives or subject matter experts dispersed throughout the world.
The Theater is an immersive environment with digital surround sound and three high-definition
projection images on a 180-degrec curved screen. In the Theater, the visual and audio experience
of a flight simulation is so realistic that Boeing installed steady bars for customers to balance
themselves.
Interestingly, as impressive, and state-of-the-art as the Collaboration Center is, Boeing
does not think the Center will look the same in three years. The aerospace giant is already
anticipating how augmented reality and virtual reality technologies will impact the firm's
collaboration with its customers.
