Apple‘s U.S. Patent No. 8,787,006 for a “Wrist-worn electronic device and methods therefor” describes a wearable touchscreen device that can be docked into a wrist strap, turning it into a smartwatch. One illustration names it “iTime”.
The device connects to an iPhone, iPad or computer to access information and receive alerts. Its strap could contain haptic mechanisms, various sensors, biometric components, GPS modules, NFC antennas, Bluetooth packages, and/or proximity detectors. Arm movement gestures could be used to control the watch, eliminating the need to touch the screen.
