The Whereabouts Clock

Microsoft Research Cambridge has come up with a new device that is reminiscent of the Weasley’s family’s clock in the Harry Potter books – dubbed the Whereabouts Clock – which lets you see whether family members are at home, work, or school. What makes it science and not magic, though, is that the device uses cell phone data to get each family members location. Basically, when you arrive at a location that you want the software to recognize, you input that location and the software searches for the nearest cell towers and uses them to get a general fix. That data is then associate with work or home or whatever. Right now the Whereabouts Clock is only a research prototype, but there are plans to test a home version in selected households in the Cambridge area.
