The ZYPAD is a wearable computer developed by military contractor Parvus and Eurotech. It works similarly to a standard laptop even though it is worn on the wrist. The device works through touchscreen control like a Smartphone and some models come with a pen that can be detached from the device itself. The ZYPAD can run either Linux or Windows CE. It can also sense motion, allowing for possibilities such as going into standby mode when the user lowers his/her wrist.
