I was flying through the Greenville, SC airport a few weeks ago when I noticed some Flight Information Displays with an unusual static sign on them – “Do Not Touch Screen”.

This tells me not only has the public embraced digital signage, but they want to interact with it.   The advancements in touch screen technology from personal communication devices such as iPhones and Blackberries have trained us how to interact with content and as a society we have come to expect every LCD display to be respond to our touch.

As interactivity becomes more common it will be less about the content and more about the experience.  Just telling your client about your latest promotions or programs won’t be enough.  They will want to touch it, resize it, make it larger, zoom in, or move on to something that is of more interest to them all of this while providing an experience that is fun and cool.

The inevitable trend for 2009 and beyond is interactivity, so if you are considering digtial signage you should investigate making it interactive.
