For the past few years you've been working on the Transborder Immigrant Tool, which sounds like it's really going to chafe the asses of millions of people--civilians and government entities alike. What was the impetus for this project?
My research lab at Calit2 is called BANG Lab, which stands for Bits, Atoms, Neurons, and Genes. One of the areas I've focused on since I've been in San Diego is developing what we call border-disturbance technologies.
What is the device, exactly?
We looked at the Motorola i455 cell phone, which is under $30, available even cheaper on eBay, and includes a free GPS applet. We were able to crack it and create a simple compasslike navigation system. We were also able to add other information, like where to find water left by the Border Angels, where to find Quaker help centers that will wrap your feet, how far you are from the highway--things to make the application really benefit individuals who are crossing the border.
Are you worried that you're going to rile anti-immigration militias?
One of the first things we did at BANG Lab was to interfere with the Minuteman Project in 2005. They were quite angry because not only were we committing public actions against them, but Calit2 and the UCSD system were also supporting it. They're well aware of who we are and what we do. Once they get full knowledge of the Transborder Immigrant Tool--and we're very transparent about it--I'm sure they'll be quite critical.
