I think an interesting player to keep an eye on is Augmate. They were an original Google Glass partner, and they develop wearable IoT control devices (such as glasses), as well as the platform that other companies can use to develop their own applications.
They use their own coin and block chain technology to allow their IoT wearables to work with different supply partners, without an intermediary.
