Digital Signage, that is the use of elelctronic screens for advertising and information, is becoming common in public places. LCD screens are now big, bright and cheap enough to put up to display notices. There are specialist hardware and software products for driving the screens, or a small general purpose computer can be used. The content can be delivered over the Internet. One LCD screen has been put up at the entrance of the ANU Computer Science and Information Technology (CSIT) Building which will be driven by experimental software. Some of the content will be automatically extracted from the web, to reduce the need to manually maintain the content.
One of the hardest parts of installing digital signage is finding somewhere to put the sign. The sign needs to be somewhere easily seen, but not where it will be in the way. It also needs mains power and data communications cables (unless wireless data is used).
