Wearable drones concepts

Wearable drones may be buzzing on the horizon. As drones become increasingly sophisticated, they will soon take on the roles currently performed by smart phones, tech futurist and designer Adam Pruden argued in a talk at the South by Southwest Interactive Festival on Saturday (March 14 2015). The future may hold wearable drones that interact with users, other people and objects in public space; as the skies fill with drones, they may even get their own superhighways and charging stations to go long distances, he speculated. Pruden and industrial designers at the firm frog tried to envision how these wearable flyers would work, and came up with conceptual designs for four different wearable drones. because of these things future works may be very easy.
you can get some idea about wearable drones from following picture.

wearable drones are used in many applications.

Breath

The Breathe is a small plastic drone that sits on the shoulder when not in use. The plastic lung is constantly sensing pollution levels in the immediate vicinity, with air filtering in thanks to a small propeller hidden in the base.

Air filter

When levels of pollution get too high, the propeller launches the drone into the sky, where it flits in front of the user's face and filters pollution form the air that they breathe.

Flying umbrella

The drone is filled with humidity and temperature sensors that can detect exactly when the weather takes a turn for the worse. If ultraviolet radiation levels get too high or rain is on the way, the drone's propellers launch it upwards and form a large disk that constantly adjusts its position to protect the user from the environment.

playmate

When a user launches the scout, the propellers expand and the scout can climb up a sheer rock wall, identifying a climbing route that is the perfect challenge for the climber's skill.

Tour guide

When the user wants to find something, such as a good ice cream shop, he or she simply gives verbal commands, and flicks their wrist to deploy the drone. The drone flies up to scout the environment and hovers a several feet in front of its owner, guiding the person through a city. 

Drone cameras

when user want to get a selfie, the drone fly around you, to take a photo.
