== Data Mining/Analysis Contest == '''In addition, it It is proposed that the raw collected data be made available in real-time to the attendees, and that a contest be held for the most interesting use of that data by the end of the conference''' (such as: mapping attendee travels; heat-mapping sessions; doing fine-grained user location to determine who interacted with who at the conference; determining how many people left in the middle of each session; calculating the number of trips to non-session areas such as the break room, Tim Horton's, or the registration desk; mapping when people gave feedback on a presentation; calculating tardiness; figuring out which presentations ran overtime; etc...) The data set for the conference will likely consist of:* about 42000 samples, each of which will consist of about 10 access point strength indications, GPIO button indications, the MAC address of the device, the approximate physical location, and the battery status* reference data, which will include floorplans of the event, the talk schedule, and reference AP strength indications at select locations throughout the conference
