Itsy Pocket Computer
Encyclopedia
The Itsy Pocket Computer is a small, low-power, handheld device with a highly flexible interface. It was designed at Digital Equipment Corporation
's Western Research Laboratory to encourage novel user interface development—for example, it had accelerometer
s to detect movement and orientation as early as 1999.

Accelerometer
An accelerometer is a device that measures proper acceleration, also called the four-acceleration. This is not necessarily the same as the coordinate acceleration , but is rather the type of acceleration associated with the phenomenon of weight experienced by a test mass that resides in the frame...
