Digital signage is a form of dynamic communication that generally comprises replaying digital media as slideshows and short films on digital display screens such as TVs, touch screens or projectors in public venues. It can be used for advertising, education or to provide information and, nowadays, is seen everywhere – from estate agents' windows to doctors' surgeries to shopping centres. This has been driven primarily by the falling price of digital screens. In this article, Keith Barrand describes the practical aspects of setting up and running simple digital signage in the practice waiting room, and suggests how to make your content relevant, lively and interesting.
