The action button control, found in the My Controls menu, allows an HMT user to change the result of a single press of the Action Button.
By default the Action Button control is present in My Controls and set to Home Screen mode, meaning that pressing the Action Button will return the user to the Home Screen. This has been the sole function of the action button since the first release of the HMT.
Saying “ACTION BUTTON” while in My Controls will activate a selection for the HMT user. “HOMESCREEN” and “NOISE CAPTURE” are the two options and the text below the ACTION BUTTON command shows the current setting. In the example above, the current state is HOMESCREEN and the command “NOISE CAPTURE” may be selected.
When set to Noise Capture mode pressing the Action Button will alternatively disable or enable the noise cancellation ability of the HMT, allowing external noise to be captured in video/audio transmission and recordings. A single press of the Action Button enters Noise Capture mode (and disables noise cancellation); this displays a warning on the screen while active and voice commands will not be recognized. Another single press of the button reinstates noise cancellation and restores voice command ability. Voice commands are disabled because non-noise captured sound will usually launch unwanted commands.
