Detecting whether Glassware was launched via voice command or the touch menu

[GoogleCodeExporter]

We would like to have different behaviors when a glassware is launched via "OK 
Glass" voice command vs touch menu. 
Specifically we are trying to prompt voice recognition if the glassware is 
launched via "OK Glass" voice command, otherwise go direct to the glassware if 
it is launched from the touch menu.

My Use case:
Data in my app can be entered by either accepting voice input (via the 
recognizer intent) or by browsing and selecting stuff. If the user has entered 
the app via touch, it would probably mean he/she prefers to browse (and not 
talk) and can be sent directly to the browsing experience.

Use case: To keep from surprising the user, provide an indication about how a 
Glassware application was launched (e.g. via voice, touch, or other). The 
launched application could then be sensitive to "preferred" user interaction 
style.

Use case: In my app I would like to have two ways of selecting the data do be 
displayed: Using voice input or browsing the touchpad. So, if the user uses 
voice input, the app would launch the final activity, otherwise the user would 
have to go through a couple of screens to select the data to be displayed. 
Similarly to what happens with "Play a game with...".
