Requirements
Requirements
Design a wristband to do:
• Access control
• Location
• Profiling / feedback
• Crowd monitoring
• Integrate with 3rd party applications
• Something that adds to the UX
11/17/1410
Access control
• Should always work
• Should be secure
…simplicity is essential: Passive RFID
11/17/1411
Location
• Ability to locate individuals
• Ability to locate security personnel
11/17/1412
Profiling / feedback
• How do the visitors behave?
• What acts are popular?
11/17/1413
Crowd monitoring
• Find hotspots in the flow of people
• Dashboard for security personnel

UX
• UX is key
• Comfortable
• Match the festival
• Suitable for non-nerds

The plan
The setup
• Set up base stations around the terrain
• Wristbands will report status
• The base stations triangulate and consolidate the data
• Visualize and push the data to other applications
• Use regular passive RFID for access control11/17/14

Something cool
• LED lights on the wristbands, integrated with the light show
• A button to send Facebook friend requests
11/17/1418
The protocol
• Time slotted protocol
• All base stations synchronise with each other
• Visitor bracelets send every few minutes
• Staff bracelets send every few seconds

Hardware
Hardware
• One 3V battery for 3 days
• Leather
• Branded for the festival
• < $10 per bracelet
