An anonymous reader writes "Japanese researchers unveiled yesterday a pocket-size telepresence robot called Elfoid. The device, which looks like a little ghost, transmits voice and motion over a 3G network to convey a person's 'presence' to a remote location. It's a creation of Hiroshi Ishiguro, a professor at Osaka University who is known for his lifelike teleoperated androids. The Elfoid has a limited range of motion, but its creators are planning to equip it with mini-actuators so it can imitate the movements of the person on the other end of the line. With vaguely formed features, the device is designed to be a surrogate of people of any age or gender."

suraj.sun writes with this excerpt from the Orange County Register: "Frustrated by students habitually skipping class, police and the Anaheim Union High School District are turning to GPS tracking to ensure they come to class. The six-week pilot program is the first in California to test GPS. Seventh- and eighth-graders with four unexcused absences or more this school year are assigned to carry a handheld GPS device, about the size of a cell phone. Five times a day, they are required to enter a code that tracks their locations – as they leave for school, when they arrive at school, at lunchtime, when they leave school and at 8 p.m."

tad001 writes "The Japanese phone giant KDDI has developed a way to track users' movements in fine detail. It works by analyzing the movement of accelerometers, found in many handsets. Activities such as walking, climbing stairs, or even cleaning can be identified, the researchers say. The company plans to sell the service to clients such as managers, foremen, and employment agencies."

Be careful just how you vent online is the lesson from this story pointed out by reader kungfugleek, from which he excerpts: "A University of Minnesota student has been banned from the Twin Cities campus after three of her instructors felt threatened by some of her Facebook postings. Amanda Tatro was patted down and questioned by campus police when she got to class Monday. The 29-year-old mortuary science student had posted comments on her Facebook page after breaking up with her boyfriend. She told her Facebook friends she wanted to stab a 'certain someone in the throat' with an embalming instrument. Tatro said she was 'looking forward to Monday's embalming therapy.' When the instructors learned of the postings, they contacted police." The Star-Tribune's account offers more detail.
