Blocks wants to make the perfect wearable with a modular smartwatch

The idea is actually pretty interesting. It would essentially make each link in the watch band into a computing module. These modules could be swapped out with a ton of different options, like a camera, GPS, heart rate monitor, microphone, SIM card, and more. You would also be able to choose between a touchscreen, eInk display, or non-touch LED. This means you could make the smartwatch into whatever you want, like a fitness tracker, or a more business-centric device with gesture controls and a fingerprint scanner. 

Of course, while the idea sounds great, we do see one major issue with it in reality - the customization of the Blocks watch is limited by your wrist size. With Project Ara, if you want more customization options, you get a bigger phone. It may be a bit tough to use with one hand, but it would still be fine. However, with Blocks, no one is going to add more items to the band past the size of their wrist, because then the device just falls off. Blocks doesn't apparently see this as a problem, but if relatively basic wearable blocks like GPS and accelerometer are separate, and you have small wrists, you could run out of options fairly quickly. 

Still, the overall idea looks like a tinkerer's dream. You can build the smartwatch that you want, upgrade it as necessary, and even choose the materials. And, it would be an open platform, so anyone could build modules for it. The only question left over is what the software would look like. Blocks says there would be apps for calling, email, Twitter, fitness, navigation, voice commands, media, and more. More than likely, it would be running proprietary software. 

No word on when Blocks might become a reality, but is supposedly "in production" right now.
