Today at Google I/O we got a chance to play with Meta Watch, Fossil's wearable development platform, which allows developers to extend the interfaces of devices and applications to the wrist. Both watches -- one analog / digital with a traditional dial plus two small OLED displays, the other digital with a larger memory-in-pixel LCD (a highly reflective, always-on, ultra low-power screen) -- feature Bluetooth for communication, along with a vibration motor, three-axis accelerometer, and ambient light sensor. The devices are built around Texas Instrument's super efficient MSP430TM microcontroller and CC2560 Bluetooth radio and will run seven days on a charge. A set of contacts in the back allow the watches to interface with a debugging clip for charging and JTAG programming. The hardware is paired with an SDK which allows a tablet or smartphone running Android to register button presses and receive sensor data from the watches, and then respond by sending text or triggering th...
