Abstract
A system and method for selecting a target device out of a larger group of candidate devices for rendering a response from a virtual assistant to an end-user is disclosed. The system determines that a same trigger phrase included in an utterance has been received by multiple devices that are in proximity to one another at around the same time. These candidate devices can collect attention data, such as user gaze toward a device, to select the device that was most likely the intended recipient of the utterance. The system is configured to control the virtual assistant to render a response solely via the selected device.
