Designed by Japanese tech firm Adplus, the Elephant Steady latches onto the back of an iPhone 4S or higher (or 5th-gen iPod touch) using a built-in holder. It also has a hard-wired 3.5-mm plug, that goes into the phone’s headphone jack.
Once the Elephant Steady is powered up and its accompanying app is launched, the iPhone’s own processor and gyroscope come into play. As soon as any slight tilts or side-to-side movements of the phone are detected by the gyro, the processor instantaneously responds by triggering the Elephant’s motor to move the phone correspondingly in the opposite direction, thus canceling out the initial movement.
