Increased accessibility of these mobile technologies, including smartphones, personal digital assistants and touch pads (ultraportable computers), has made them more feasible for use by consumers for selfmonitoring but also by researchers and health care service providers for monitoring health behavior, compliance and effectiveness. Mobile technologies can be used in a cocreation mode where users provide input and actively participate in the cocreation of service, care and best practice. The presentation illustrates some of the new technologies and give examples of how they can be applied to the study of behavioral nutrition.

Requirements

z cost‐effective and easy to doz should not rely on any active actions from participants, like for example checking‐in with cards or RFID transponders

z it should not put the privacy of participants at risk

First ideas

z we thought about RFID dongles – but they must be carried at all times... and require participants to check‐in

z almost all students have a smartphone

Why not track them using their WiFi signals?

Tracking

z Trackers are 100% passive – do not work as a rogue AP

z Capturing MAC addresses (Layer 2) that are available in the “air”

z MAC address on the device are filtered before things are being sent to the central server

Hardware

z Heart of the system: BeagleBone Blackz WiFi: atheros based regular USB wifi cardz Antennas: from 2dBi omni for small locations up to 5dBi directional antennas to cover larger areas/pickup weaker signals

z Hardware cost? Very small!z Can be reused in different projects? YES!

Software

z the board runs Linux debianz the main software running on the board is custom‐written (in Python)

z control and data backend is a web application with regular web‐based interface 

z we are using specially configured Kismet installation on each board to passively capture WiFi beacons 

Why it works?

z Smartphones with enabled WiFi send periodically beacon frames to force nearby Access Points to “reveal themselves quicker”. 

z This way the user can get the list of WiFi networks much quicker. 

z In our experiment we were counting on these beacons being sent every now and then

z It should be stated – the method is not perfect – but it is good addition to other means of testing. 

Security

z The FST tracks MAC addresses; in order to keep high morale standard we have implemented special filtering – that means –we were saving presence only for MACs defined in our database

z The list is obtained by each board automatically from the server. In case of theft there is no data on the device itself

z Everything is sent over encrypted channel

Additional functions

z we had a mapping of MAC <‐> telephone number – therefore we could send “action SMSes” to participants (depending on their location)

z as a by product we discovered “privacy friendly phones” that heavily restrict their beacon sending :) 

WiDetect panel WiDetectz since the panel is “just a website” ‐ it could be operated from any place in the world

z it works out of the box with tablets and mobile phones (responsive design)

z SMS functionality, mapping etc. is realized via the WiDetect application itself
