Development Environments


unity-150x150Unity 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 solution to accessing the WearHF Voice Service running on the HMT headset from inside a Unity Application.

There are 2 files required by your Unity application to access the WearHF service: a native Android plugin and a managed C# plugin. A Unity project will use the managed plugin to add and remove voice commands to the WearHF service.


The Unity plugin can be downloaded as a zip file which can be extracted and imported into your project.
