In a move likely to be popular among parents and unpopular among kids, Verizon Wireless today launched a new mobile phone service called Chaperone.   The service uses Global Positioning System (GPS) data to let parents track the whereabouts of their offspring—as long as they’re using an LG Migo phone.   High-tech industry research firm ABI predicted that Verizon’s launch of Chaperone could help popularize GPS-based tracking services.   “By combining tracking and cellular technologies, wireless carriers could jumpstart what has been, to date, a sluggish segment of the GPS market," ABI analyst Ken Hyers said in a statement to the press.   Hyers cautioned, though, that “vendors will need to set realistic expectations for their customers. In many cases, this will mean educating the public on the real-world availability and accuracy of cellular A-GPS.” Chaperone provides two main tracking options:Child Locator – Lets parents use a GetItNow-enabled Verizon Wireless phone, or a Web-based account, to locate a child’s Migo handset.Child Zone – Lets parents use a Web-based account to construct a geographical zone within which their child can move with a Migo handset; when the kid leaves that zone, parents are notified with a text message.
