Greetings AoIR 2016 attendees, As part of our Carnival of Privacy and Security, we are inviting interested attendees to participate in a fitness tracker swap that will take place on Wednesday, Oct. 5th. The swap will entail exchanging your tracking device with another participant along with contact information to correspond with other participants to retrieve your personal trackers. The organizers of the panel will be participating in the swap as well, and we have a couple extra devices if you would like to participate and do no have your own device. We hope the swap will encourage rich discussion around issues of the privacy and security of trackers during our session on Friday, when we will finish the swap experiment and return devices to their owners. If you are interested in participating, please email Jason Archer ( jarche2@uic.edu) and Nathanael Bassett (nbasse2@uic.edu) so we can contact you with further details about the exact time and location of the swap. We anticipate doing the swap immediately following the last workshop sessions on Wednesday but still need to finalize a meetup location. We trust that as a member of the AoIR community all participants, understanding that participation is voluntary, will apply an ethics of care and act in good faith to take care of others' personal devices, which includes doing nothing to compromise the functioning or security of the device, and with the promise of retuning devices either during our Friday session or making other arrangements if you will be unable to attend. If you are not interested in participating in the swap, we hope you still consider attending our session on Friday to enjoy the other Carnival acts we have in store. Looking forward to seeing you all soon, Jason Archer and Nathanael Bassett
