Itsy Pocket Computer
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 accelerometers to detect movement and orientation as early as 1999.
