GPS has been around for a while, but is now starting to get cheap enough that the average person can start using it – for tracking people, vehicles or pretty much anything else. The TrackStick is a battery-powered USB device that stores GPS location data at preset intervals, which can then be uploaded to a computer in a variety of formats. The implications of this technology for privacy and surveillance issues are immensely complex, but as usual the technology is here before any sort of legal framework is in place. It also take us another step closer to spimes.
