Multiple attendees can interact with the wall at once. To identify themselves, attendees need only to touch their festival badges to the screen—each badge is embedded with a radio-frequency identification (RFID) tag.
Check back later this week for more on user interface design and interactive marketing shop Schematic and the wall's potential for advertisers.
For those of you at the festival, the touchwall is located on Level 1 of the Palais des Festivals, between the entrances to Debussy Theater and Grand Auditorium. Let us know what you think of it.
