Life Microscope

Hitachi Life MicroscopeHitachi’s Life Microscope is a watch-like device the user wears around the wrist. It makes use of accelerometers to detect the user’s activity levels. Hitachi unveiled the new device at an exhibit in Tokyo this week, according to a report in Akihabara News.

At the time of its unveiling, Medgadget wondered if the wristworn device would be as accurate as others on the market since it’s attached to a limb: It “raises the question whether arm movements can fool the device into thinking that the whole body is moving.” That applies to a number of the devices on this list.
