A new patent from IBM could bring new meaning to instant coffee. The patent describes a drone that could detect when a person is tiring and fly over with a cup of coffee on demand—so no need to worry if yours is the one street corner without a Starbucks.
In its patent, IBM imagines a drone, or unmanned aerial vehicle, flying over a group of people and:
“scanning the people, using one or more sensors connected to the UAV…which identifies an individual among the people that may have a predetermined cognitive state, based on sensor data and flying the UAV to the individual that may have a predetermined cognitive state to deliver the drink.”
In other words, the drone would be able to detect barometers of a person’s energy such as blood pressure, pupil dilation, and facial expressions, and then give them a caffeinated boost as a result. These metrics could be tracked through a Fitbit-style device or even a person’s digital calendar, noting when their appointments are during the day.
