Waving to control the plane

One day unmanned aerial vehicles would be as simple as the arm waving, scientists say.

Newscientist reported Yale Song and colleagues at the Massachusetts Institute of Technology in the US have found a way to control the aircraft on the runway automatically by the arm movement.

Unmanned aerial vehicles are now able to land on aircraft carrier aircraft, but humans still have to control them in the course of running on the ship's plane. With human-powered airplanes, technicians use predefined movements to command pilots to perform tasks, such as opening a weapon compartment.

To check whether the computer recognizes these hand movements, Song's team writes a computer-aided algorithm that analyzes a three-second video of the hand movements of those who signal the machine. fly. The computer records the positions of the body, arms, wrists and fingers and analyzes. The results show that it accurately determined 76% of the number of movements in the video.

The team says they are continuing to improve the algorithm to increase the accuracy of the computer.
