TalkBack enables any device to act upon queued commands. For example, if you have a door that is outfitted with Wi-Fi and a motion sensor, you can queue up commands to open and close the door. When the door senses someone nearby, open the door. After a specified period of time, close the door. If there are no more commands in the TalkBack queue, the door does not open when the next person approaches.
Create a TalkBack using the web interface. After you create the TalkBack, use the web interface to control the TalkBack queue, or TalkBack API test.
