The Unity plugin package comes with an example app that shows the plugin being used inside an Android Unity App.
Install the example app on a HMT following the install instructions.
When the app is run the device camera feed is displayed full screen with the RealWear logo pulsating in the top left corner.
There are 2 on-screen buttons. One pauses the camera feed to produce a still image of whatever was being viewed and the other re-activates the live feed when paused.
The 2 buttons have been voice enabled using the plugin using the technique described in the tutorial.
