Microsoft Shifts Smart Watch Prototype Testing to Surface Hardware Team
The move to the Surface group underlines a recent organizational change at Microsoft that aligns Xbox hardware and Surface hardware into a single division, with former Windows chief Julie Larson-Green now responsible for all of Microsoft's hardware efforts.
In addition to a potential Surface connector that could allow a smart watch to interface with existing Surface tablets, Microsoft is also said to be testing smart watches that have 1 1.5-inch display, a heart rate monitor, and are running a modified version of Windows 8.
As Microsoft experiments with its smart watch, it appears Apple is in the prototype stages as well. According to a report yesterday, Apple has begun "aggressively" hiring new employees to help with the smart watch, which is now expected to be released in late 2014. Apple's own smart watch is expected to run the full version of iOS and could include a heavy focus on biometrics and health related applications.
Along with Microsoft and Apple, both Google and Samsung are said to be working on smart watches of their own. At this point in time, it seems all companies are in the testing phases with no indication of which smart watch might hit the market first.
