A gimbal is an important piece of technology that makes for some smooth video. It's the device that stabilizes the camera so you can get that cinematic look in your shot. It removes the vibration and shake. The gimbal's motors keep the camera level as the camera operator moves it. Drones use them, the DJI Ronin is basically a large gimbal, and the DJI Osmo is the latest handheld gimbal that DJI brought to market.
Simply put, a gimbal rapidly moves in the opposite way you're moving in to remove the shaking motion as much as possible. Gimbals were first used in ships to stabilize the ovens onboard, but the electronic gimbal is used a lot in photography and video production today. Wikipedia explains it as follows: "With the guidance of algorithms, the stabilizer is able to notice the difference between deliberate movement such as pans and tracking shots from unwanted shake. This allows the camera to seem as if it is floating through the air, an effect achieved by a Steadicam in the past."
And the same stabilization technology can be applied in other industries where it is needed. Liftware is a company that has developed a utensil for people with Parkinson's Disease who struggle to get the spoon to their mouth when they eat. The utensil reduces shake by up to 70 percent. We know creative ideas can occur when two or more concepts of totally different origin or industry are combined. For me, this is one of those. We are living in the future.
