　　该团队能够确定果蝇如何使用眼球运动来快速协调它们的翅膀以响应它们所看到的。由于苍蝇的眼睛固定在头部，研究人员跟踪头部运动来推断苍蝇在看哪里。稳定凝视是大多数生物都能做到的普通现象；例如，人类无缝地移动他们的眼睛、头部和/或身体来扫描房间。

　　虽然该领域之前的大部分研究都集中在机翼运动上，但了解像苍蝇这样的动物如何使用主动眼球运动来控制飞行可以大大增强机器人技术。目前，大多数机器人都有固定传感器，保持传感和运动分离。但是，通过能够在身体上移动的视觉传感器的协调，更好地模拟眼睛和大脑，机器人的飞行控制可以大大改善。

　　为了支持这一理论，研究人员确定果蝇的眼睛的反应速度比动物的身体或翅膀快四倍。这些反应也紧密耦合，表明苍蝇严重依赖眼球运动来协调它们的翅膀运动。通过减少运动模糊，他们的眼睛可以比最初想象的更好地控制和稳定他们的视力。

　　此外，他们发现，当苍蝇小心地将胶水涂在头上，然后在虚拟现实飞行模拟器中进行记录时，它们头部运动的限制对飞行性能产生了巨大的影响。发现的一个重要原理是，苍蝇的眼睛减慢了进入大脑的视觉运动，这个过程增强了它们的飞行行为。在这项工作中，研究人员相信解开生物世界的秘密可能会对技术产生广泛的影响。

　　The team was able to determine how fruit flies use eye movements to quickly coordinate their wings in response to what they were seeing. Since fly eyes are fixed to the head, the researchers tracked head movements to infer where the flies were looking. Stabilizing gaze is an ordinary phenomenon that most living things can do; for example, humans seamlessly move their eyes, head, and/or body to scan a room.

　　While much of the previous research in this area has focused on wing movements, understanding how animals like flies use active eye movements to control flight could greatly enhance robotics. Currently, most robots have stationary sensors, keeping sensing and movement decoupled. But by better emulating the eyes and brain through the coordination of visual sensors capable of moving on the body, the flight control of robots could be vastly improved.

　　To support this theory, the researchers determined the eyes of the fruit fly were able to react four times faster than the body or wings of the animal. These reactions were also tightly coupled, demonstrating that flies rely heavily upon eye movements to coordinate their wing movements. Their eyes can control and stabilize their vision better than originally thought by reducing motion blur.

　　In addition, they found that when the flies had glue carefully applied to their heads and then recorded in the virtual reality flight simulator, the restriction of their head movements had a dramatic impact on flight performance. An important principle discovered was that fly eyes slow down visual motion that goes into the brain and this process enhances their flying behavior. Demonstrated in this work, the researchers believe unlocking the secrets of the biological world could have broad implications for technology.
