Ever since the Pebble Smartwatch got millions in funding from Kickstarter, other companies have been coming out of the woodwork in hopes of getting a smartwatch on your wrist. The Martian smartwatch is a slightly different take on the concept, though. These devices would be based mostly on voice commands over Bluetooth.
The video is clearly using a lot of Siri commands, which Android devices won't support. Since this is essentially a fancy Bluetooth device, all the voice commands that work through a regular Bluetooth headset on your phone will be available with Martian. If you've got S Voice or Google Now you should have a fair number of functions, but it's not going to be consistent across devices.
