I have been searching for Augmented Reality use on exhibition stands for some time now…here is a good link and example of its use for those not initiated in this form of tech use http://twurl.nl/hhnffo
“A webcam was built into the stand to detect the customised marker. The marker itself was printed on the back cover of the event guide, embedded within the hat of the model, with visitors being directed to the stand to ‘see inside the mind’ of the consumer.
Once at the stand, the guide was held up to the webcam, and the visitor saw a number of animated facts relating to the consumer spring from the guide on the plasma screen directly in front of them. As you can see, from the video (above), it got a great response!”
