Museum signage not only requires careful editorial and design skills, the placement and lighting is important as well. Sometimes the content is multilingual and usually a stop number is visible for an audio tour. Changing the object's location, temporary removal or discovering a typo requires the label to be removed and recreated. Also a revised audio tour also might have consequences for the signage. And all these changes don’t come cheap.

That’s why I was triggered by the introduction of a signage device based on low power electronic ink that could be programmed as much as you like. The text could be managed by the museum staff remotely by a web based CMS, or linked to the audio tour management system. It has APIs for this.
