iPhone 4S + Siri + Bluetooth 4.0 = Awesome Smart Watch Josh Smith10/07/2011 The iPhone 4S is the first Bluetooth 4.0 phone to arrive on the market. Bluetooth 4.0 is a new version of the popular Bluetooth standard that allows you to connect a variety of devices to your smartphones and notebooks. Bluetooth 4.0 brings several new features to smart phones, accessories and computers. Here are a number of reasons why you should be excited to know that the iPhone 4S has Bluetooth 4.0. If you thought Siri sounded like science fiction, how’s this new smart watch sound? What’s new in Bluetooth 4.0? One of the biggest differences between Bluetooth 4.0 and earlier Bluetooth standards is that the new version of Bluetooth uses less power, but thats not all that you get. The most exciting art of Bluetooth 4.0 is that the new standard can wake up devices on command. This new standard helps make a whole host of smart connected devices possible — like smart watched and health monitoring devices. There is also a new no-code pairing system that will simplify the connection process, and some argue could give Bluetooth the chance to pull of NFC type activities such as sharing information with another phone or even making payments.Advertisement Why I’m Excited for Bluetooth 4.0 Smart Watches Metawatch The iPod Nano is appealing because it can be turned into a watch that does more than tell time. With the addition of 16 new watch faces I think Apple will sell more of the Nano. Perhaps we’ll see a new iPod Nano in 2012 that has Bluetooth 4.0 and smart watch features, but until then I am most excited about devices like the Metawatch. The Metawatch is able to connect to devices over Bluetooth and receive push notifications for things like email, texts, caller iD and more. Right now there is no iPhone support, and the watch doesn’t appear to use Bluetooth 4.0 technology, but I expect to see this device or similar takes on it arriving in the next year with Bluetooth 4.0 and iOS support. Siri + SmartWatch = Awesome This product doesn’t yet exist, but it might sound like the Dick Tracy Watch everyone is trying to make. Imagine a Bluetooth 4.0 powered watch that rarely needs charge, can have the display awakened when you get a new notification, support for apps and customizable display functions.Advertisement Awesome.Advertisement Now add in support for Bluetooth voice connectivity. Not to make calls, but instead to control the new Siri assistant app that is launching with the iPhone 4S on October 14th. Instead of taking your phone out of your pocket or relying on a Bluetooth headset, you could just raise your wrist to your mouth and ask Siri to do something. In addition to convenience, you get to pretend you are a secret service agent. I know that I would buy this watch in a hearbeat, which is something it could also monitor. While we’re at it, build in some fitbit type software and someone make me a Bluetooth 4.0 door lock that I can undo with my watch. I hope this Bluetooth connected future gets here sooner rather than later.
