This is eerily similar to the concept of a 'cookie' seen in the Black Mirror episode, White Christmas. (Spoiler Alert)

A cookie is a device "that is inserted under the clients head by the brain and kept there for a week, giving it time to accurately replicate the individuals consciousness. It is then removed and installed in a larger, egg shaped device which can be connected to a computer or tablet (to automate their smart house controls as if the house was knew their personal preferences moving from room to room.)"
