It would know when you need a caffeine boost and fly over with your fancy coffee.
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.
IBM's scenario offers multiple options for coffee delivery. The coffee drone could be also be summoned by a hand motion, for example. There are also multiple options for delivering the coffee itself. One hypothetical has coffee poured directly into a person's mug, while another offers a full service approach by delivering coffee in a sealed bag to protect the recipient from getting poured on from above.
