The LED sign placed in our group’s entrance sparked conversation.

Casual displays are displays meant to integrate information into the common areas of our workplace environments rather than personal or desktop workspace. Casual displays include such things as scrolling LED signs and spoken background audio. When placed in common areas, these displays can also serve as a modern "water cooler" by stimulating group communication about their contents.
We have built a prototype server that automatically takes information from a variety of sources such as Lotus Sametime, Notes group calendars, mail-in message databases, and Web sites and displays it on several casual display devices. One such device, a scrolling LED sign shown below, was located in our main entrance. During the course of the summer, the information on the ticker frequently prompted new discussions.
The Casual Display server is implemented in the Java programming language and runs on the Sun Microsystems JRE 1.3. The architecture is designed to be scalable and has been tested with a variety of display devices, including WAP-based cell phones, speech synthesizers using VoxML, and Palm Pilots with infrared beaming capability in addition to programmable LED signs. The underlying requests are represented with XML, and the server uses XSL to convert the requests for the individual displays.
At this time, we are investigating deployments of such displays in customer organizations, both internal and external, to analyze how people use them.
