Anonymity

The participants can retain their anonymity with respect to the other participants and the outside world until they decide to participate to the live evaluation. Although they may use a pseudonym, they need to provide a valid email address so the organizers can communicate with them. To enter the live evaluation and compete for prizes, they will have to reveal their true identity. Participation requires registering by signing up to the Google group gesturechallenge. This requires having a Google account.
