A device and method with query device allocation. The method includes receiving, via a user interface of an electronic computing device, a user query, obtaining an initial result and determining a cognitive load of a user of the electronic computing device based on a characteristic from a sensor. The method further includes comparing the cognitive load to a cognitive load threshold, transmitting the initial result to an operator device when the cognitive load exceeds the cognitive load threshold, receive, from the operator device or another device, a revised result and outputting the revised result via the user interface.
