Unity applications do not function in the same way that standard Android applications do, so WearHF is not able to interpret them in the same way out of the box.
However, we have developed a plugin that enables speech commands to work in Unity applications with a small amount of development.
The Unity Plugin is RealWear's official solution to accessing the WearHF Voice Service running on the HMT-1 from inside a Unity Application.
For information on how to develop your Unity Application for the HMT-1, please see our Unity Plugin page.
