Consider the most common uses for a tablet. Now, think about each one assigned to an individual device you wear on your wrist. In 2004, that’s what HP researchers did, and some. As outlined in this document, the proposed line of smart wristwatches included the Info Watch, which offered web access, the Digital Wallet, which provided mobile banking, the Family Awareness Watch, a creepy GPS tracking system, and the Web Cam Watch, which provided streaming real-time video playback on a wristwatch. Perhaps the most impressive was the Shop Watch, which boasted ahead-of-its time RFID scanning and Shazam-like capabilities for tagging music or bookmarking advertisements for reminders later on. The only problem was the smartphone soon did all the same without the need to wear five watches at the same time.
