Is there a way to insert the "ok, glass" trigger into an immersion activity on Glass? I want to make the launch of my application as seamless and quick as possible. Making an immersion application seemed to be the way but I can not find a way to bring up the "ok, glass" footer trigger within my activity to launch my application menu to be navigated hands free. Any clue as to how this works?
Note: I have a voice trigger to launch the app from the Glass home screen.
I'm not creating a card but rather just using an XML layout as I'm changing text on the screen dynamically to user interaction using an AsyncTask. Any advice would be great.
Contextual voice commands are not yet supported by the platform, feel free to file a feature request in our issues tracker.
UPDATE: as mentioned in the comments and the other answer, contextual voice commands are now part of the platform for Immersion: https://developers.google.com/glass/develop/gdk/voice#contextual_voice_commands
As of XE18.1 and GDK Preview 19, contextual voice commands are available in the GDK. Documentation is available at https://developers.google.com/glass/develop/gdk/voice.
