We created a stand of 60 square meters: it was small but packed full of activities. We also co-ordinated local suppliers of audio and video technology for several symposia. For the stand we have created a “virtual tree” – a multimedia installation formed from 10 iPads which 110 users interacted with. We even set up an augmented reality corner. The iPad application was designed to visualize the results of a satisfaction questionnaire in real time. After answering a questionnaire the user could check how their feedback related to that of the nine other participants. The interaction was handled by a local server which controlled the iPads via wi-fi. Meanwhile, augmented reality was used with two iMacs and two printed books displaying scientific content. The pages of the books were fitted with electronic tags. Two web cams were installed into a pair of table lamps that shone on the books. The user could browse the book and when the web cam read a tag, its content appeared on the computer monitors as a 3D animation. The stand also featured two 55″ monitors, where related content could be accessed and controlled using an iPad. The backdrop of the stand was dedicated to medical topics with monitors displaying videos and questionnaires.
