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 in Palo Alto to encourage novel user interface development—for example, it had accelerometers to detect movement and orientation as early as 1999.^[1]^[2]

The Itsy prototype has a 200-MHz StrongARM SA-110 microprocessor, a hi-res LCD touch screen, an audio codex, and 64MB of memory and runs on a pair of AAA batteries. But don't look for the Itsy in stores. It's strictly a research platform, designed to encourage collaboration and development of next-generation computing appliances and software...
