Technologies for managing cognitive assistance provided to a user of a cognitive assistance system include a cognitive assistance system to determine a cognitive state of the user based on sensor data generated by one or more biosensors of the cognitive assistance system. The cognitive assistance system determines whether the user requires assistance based on the determined cognitive state of the user and identifies, in response to determining the user requires assistance, a trusted mobile computing device within a vicinity of the cognitive assistance system based on a trust relationship previously established between the cognitive assistance system and the trusted mobile computing device. The cognitive assistance system further communicates with the trusted mobile computing device to notify a remote user of the trusted mobile computing device that the user requires assistance.
